Why this matters: PEX is the backbone of modern residential and light commercial water distribution. Choose the wrong system—or buy the wrong-grade fittings from a random supplier—and you’ll inherit callbacks, leaks, and code headaches. I’ve spent 25+ years installing, repairing, and specifying PEX on everything from mid-rise apartments to custom homes. Here’s the straight talk you won’t get at a big box aisle.
Crimp vs. Expansion: The Decision That Shapes Your Whole System
When we talk PEX joining methods, we’re primarily comparing two ASTM pathways: F1807/F2159 crimp (including stainless cinch F2098) vs. F1960 expansion. Both meet ASTM F877 for SDR9 PEX tubing. Both are code-approved under IPC and UPC. But they behave differently on the job.
- Crimp (copper rings) and Cinch (stainless clamps) compress a fitting barb into the tube. Tools range from pocket-friendly hand sets to ratcheting heads. Visual gauge checks confirm sizing. Expansion stretches the tube with an expander cone; the tubing’s memory shrinks back to seal on the fitting and expansion ring. It’s elegant, especially in cold climates or tight manifolds.
Which is “better”? Depends on budget, labor, water chemistry, pressure/temperature, and who’s holding the tool. I’ll map it out, brand by brand, detail by detail, so you can buy once and install right.
Pro tip: If you’re mixing systems across phases—for example, crimp in units, expansion for mains—standardize on an inventory plan early. We help contractors build a SKUs-by-building spreadsheet so you’re never short a 3/4 x 1/2 reducing tee at 5 p.m.
Understanding the Materials: PEX-a, PEX-b, PEX-c and Why It Matters
PEX tubing types often get oversimplified. Here’s the real-world version:
- PEX-a (peroxide method—think Uponor/Wirsbo, REHAU) is most elastic, ideal for F1960 expansion because it recovers quickly. Great freeze tolerance. PEX-b (silane method—Viega, SharkBite, Apollo) is stiffer, economical, and excels in F1807/F2159 crimp or F2098 cinch. PEX-c (electron beam) sits in the middle on flexibility; fewer mainstream North American lines but still valid in many crimp setups.
All three must meet SDR9 dimensions and F877 performance: commonly 160 psi at 73°F, 100 psi at 180°F, 80 psi at 200°F. Chlorine resistance and UV limitations vary by brand—no PEX likes sunlight; keep exposure under manufacturer limits (often 30–60 days). In high-chloramine cities, verify the CLS (chlorine) rating on the spec sheet. We stock those sheets at the counter—ask for them.
Insider secret: On multifamily jobs using recirculation, confirm the hot return loop’s PEX brand is rated for the continuous temp you actually run—140°F continuous can stretch the wrong line to failure over time.
Crimp and Cinch: Simple, Fast, and Budget-Friendly
If you want dead-reliable and affordable, F1807/F2159/F2098 is your friend.
- Tooling: A good copper crimp set runs $60–$150. Stainless cinch tools fall in the same range. Look at Milwaukee 48-22-6307 or RIDGID 43853 for ring crimpers; Oetiker and Apollo for cinch. Fittings: Brass (F1807) or polymer (F2159). Union tees and 90s from Viega PureFlow, Apollo, and NIBCO are contractor staples. Ball valves: Apollo 94ALF series lead-free. Verification: Use a go/no-go gauge—takes 3 seconds and keeps inspectors happy. Speed: A practiced tech can rough a 2-bath home in 6–8 hours with a two-person crew using manifolds and homeruns.
Where it shines:
- Budget-sensitive projects Service work (keep a small bin of rings and fittings in the truck) Small diameters (3/8 to 1 inch) with many drops
Potential pitfalls:
- Over-crimping ovalized tubing—always cut square and re-round if needed Mixing brand rings/fittings outside spec—stick to the listings
We see crimp/cinch materials tally 20–35% lower material cost than expansion on typical single-family builds.
Expansion (F1960): Flow, Freeze Performance, and Premium Fit
F1960 expansion uses an expander tool with stepped cones; the ring goes on the pipe, you expand the assembly, then slip it onto the fitting. Milwaukee M12 ProPEX Expander Kit 2432-22 and the M18 2633-22, plus Uponor’s EP fittings and ProPEX rings, are the workhorses. REHAU EVERLOC+ is a similar high-performance expansion-compression hybrid with great pull-out strength.
Why pros pick expansion:
- Larger internal diameter at the fitting. With PEX-a, you typically gain a size in effective ID vs. crimp at the joint. That helps with fixture unit counts and hot water delivery. Cold-weather installs: the elastic recovery bites down even in lower temps. Visual confidence: if the ring is seated and marked, you know it’s home.
Tooling cost is higher: $350–$650 for a cordless expander kit. Fittings and rings can run 10–25% more than crimp equivalents. Labor time is comparable after a week of crew learning curve—call it even for experienced teams.
My rule of thumb:
- Custom homes, long hot runs, or boutique multifamily: I lean F1960. Bread-and-butter tract or service: crimp/cinch wins the math and speed.
Brand-by-Brand Setup: What We Stock and Why It Works
At Plumbing Supply And More (PSAM), we carry vetted lines because I’ve installed them, broken them, frozen them, and pressure-tested them.
- Uponor PEX-a and ProPEX (F1960): Tubing in 1/2–1 inch coils and 20-foot sticks, EP fittings, brass ball valves, and multiport tees. Tooling: Milwaukee M12/M18 kits and Uponor expanders. Viega PureFlow PEX-b: Strong F1807 brass and F2159 polymer fittings, press-sleeve options for specific projects. REHAU EVERLOC+: Excellent pull-out resistance—particularly popular with high-end builders. Apollo and SharkBite for F1807/F2159/F2098: Reliable, widely specified, service friendly. Manifolds: Sioux Chief and Viega options—home-run designs speed finish work and simplify balancing.
We also cross-stock adapters to integrate legacy copper (press or sweat), CPVC, and threaded systems. Need a transition from 1-inch PEX to 3/4 copper press? plumbing supply and more We’ll hand you a Viega ProPress adapter that plays nice with your rough-in pressure test.
Bold truth: Unlike generic big box retailers, Plumbing Supply And More stocks professional-grade components that match ASTM and NSF listings without cutting corners.
Common Jobsite Scenarios: What I Recommend and Why
- Cold-climate cabin with risk of freezing: Expansion with PEX-a. I’ve seen ProPEX joints survive freeze-ups that would split a crimped interface. Multifamily hallway mains with many tees: Expansion or REHAU EVERLOC+ to keep pressure and flow balanced. Tight chase service work: Cinch rings (F2098) can be simpler with one-handed tools in cramped spots. Water with elevated chloramine: Stick with brands with proven CLS ratings; we’ll pull the data sheet at the counter.
Pricing realities:
- 2-bath single family (crimp/cinch with manifold): Materials commonly $450–$800 depending on valve count and fixture spread. Same house with expansion: $650–$1,050, largely due to fittings and rings. Tools: Service tech crimp/cinch kit under $200; expansion kit $400–$600.
Install time:
- Speed ties to planning. Precut drops, label manifolds, and pre-assemble stub-outs. A two-person crew gains 1–2 hours simply by staging fittings per bathroom on a color-coded sheet.
Code, Inspection, and Quality Control—Don’t Lose a Day Over the Small Stuff
Every week I help contractors smooth approvals. A few points:
- Follow the standard: F877 for tubing; F1807 (metal crimp), F2159 (poly crimp), F2098 (stainless cinch), F1960 (expansion). Strap and support: IPC Table 308.5 equivalent—generally 32-inch vertical, 6-foot horizontal intervals for 1/2-inch and up; confirm locally. Firestopping: Use listed devices where penetrations require it; we stock STI and Hilti systems compatible with PEX. Testing: We advise 100 psi air or water test per local AHJ for 15 minutes minimum—more in some jurisdictions. Manifold labeling: Inspectors love clearly labeled hot/cold home-runs. It’s five minutes that saves you 20.
Need submittal sheets? Ask the counter. We’ll email a PDF pack with model numbers and standards so your inspector signs off without a second trip.
Why contractors switch to us: Compared to standard plumbing supply houses, Plumbing Supply And More offers unmatched technical support—real plumbers at the counter who can answer code questions before you roll a truck.
Tooling and Maintenance: Keep Your Connections Tight for the Long Haul
- Crimp/cinch: Keep jaws clean; verify calibration monthly. Replace worn gauges. Rings must be square to the fitting; I like a light Sharpie witness mark to confirm full seat before crimp. Expansion: Lube cones sparingly with manufacturer-approved lube. Rotate expansions for uniform stretch (Milwaukee auto-rotating heads help). In cold weather, warm rings in a pocket to speed recovery. Cutting and reaming: Use sharp PEX cutters. Burrs and oval cuts are the silent killers of perfect joints. Pressure and temperature: Respect continuous temp limits. Don’t run recirc past the tubing’s rating; mix down at the water heater if needed.
We host quick tool bench-checks at our counter—bring your expander or crimper in, we’ll test on scrap and gauge your connections.

FAQ: PEX Choices, Tools, and Specs
Q: Which is more reliable: crimp or expansion?
A: Both are reliable when installed to spec. Expansion (F1960) excels in freeze-prone areas and for better flow at fittings. Crimp/cinch (F1807/F2159/F2098) is cost-effective and fast for service and tract. The failure mode I see most is poor workmanship—improper cut, ring misplacement—not the method itself.
Q: Can I mix brands—say, Viega PEX-b with Uponor expansion?
A: Don’t mix across joining standards. PEX-b with crimp/cinch? Fine with listed compatible rings/fittings. Expansion needs PEX-a with listed F1960 rings/fittings (e.g., Uponor ProPEX). Always follow listings and your AHJ’s interpretation.
Q: What tools should a small shop start with?
A: For service and light remodel, a stainless cinch kit plus a copper crimp head for 1/2 and 3/4 covers 90% of calls for under $200. Add a compact expander kit when you start seeing expansion jobs—Milwaukee M12 2432-22 is an excellent entry.
Q: Are push-to-connect fittings okay behind walls?
A: Many are listed for concealed use and meet code (e.g., SharkBite EvoPEX), but I treat them as targeted solutions—great for service and tight retrofits. For full rough-ins, stick to crimp/cinch or expansion systems for cost and consistency.
Q: What about chlorine and recirc systems?
A: Verify the tubing’s continuous temperature and chlorine resistance rating. If you’re running 130–140°F continuously, choose a line with strong CLS ratings and consider copper on the loop if chemistry is harsh. We’ll help you spec it.
Q: What’s the lifespan of a good PEX system?
A: Properly installed and protected from UV, you’re looking at decades—25–50 years is typical. Keep to temperature/pressure limits, use listed fittings, and protect from mechanical damage.
