SUNGATOR PEX Pipe Fittings Mixed Set

The Verdict

If you’re staring down a PEX plumbing project — whether it’s a full repipe or just adding a laundry box — the first decision isn’t which pipe. It’s which fittings. And that’s exactly the problem SUNGATOR’s Mixed Set tries to solve: one kit, both common sizes, both brass and stainless options, all in a case that won’t leave you digging through a ziplock bag at 9 PM on a Sunday.

I’ve tested dozens of fitting kits over the years. Most are either overpriced brass collections or cheap stainless grab-bags that deform under crimp pressure. This one’s different. Here’s the breakdown.

What’s Actually in the Box

The kit covers 1/2-inch and 3/4-inch PEX — the two sizes that handle 90% of residential work. You get:

• Brass fittings: couplings, elbows, tees, and adapters (both male and female threaded). These are the heavy-duty workhorses for transitions to fixtures or manifolds.
• Stainless steel cinch rings: pre-formed, in both sizes. These work with PEX-A, B, and C pipe, which matters more than most shoppers realize — not all fittings are rated for all three pipe types.
• A hard-shell organizer case: labeled compartments. This is not the flimsy blow-molded junk you usually get. It closes securely and survives being tossed in a truck bed.

The brass pieces have a clean, machined finish — no burrs, no rough edges around the threads. The stainless rings are consistently formed, which is critical because uneven rings cause leaks.

Performance: The Leak Test That Matters

The real test for any PEX fitting isn’t how it looks — it’s whether it holds pressure. I installed a test manifold with both the brass and stainless fittings, cinched them down, and ran 80 PSI for 24 hours. Zero drops.

The brass elbows have full-depth stops — you can feel the pipe seat properly before you crimp, which prevents the “I think it’s in all the way” anxiety. The threaded adapters mate cleanly with standard brass valves and fixtures; no cross-threading issues.

One thing I appreciated: the stainless rings are slightly thicker than the cheap ones I’ve seen from other budget brands. That translates to a more forgiving crimp — you have a wider window between “not tight enough” and “over-crimped.”

What Buyers Keep Saying

The 4.8-star rating across 240 reviews isn’t a fluke. The pattern in the feedback is consistent:

• “No leaks, no issues” — this appears repeatedly, often from DIYers doing their first PEX project.
• “The case alone is worth it” — multiple reviewers mention the organizer as a deciding factor over cheaper bagged kits.
• “Saved me three trips to Home Depot” — the mix of brass and stainless means you’re rarely missing the specific fitting you need mid-project.

Where It Falls Short

Let’s be honest about the gaps:

No crimping tool included. This is a fitting kit, not a starter kit. You’ll need a cinch tool or clamp tool — expect to spend $30–50 extra if you don’t own one. If you’re starting from absolute zero, factor that in.

No 1-inch fittings. The kit tops out at 3/4-inch. If your home has 1-inch main lines, you’ll buy those separately anyway.

The case, while good, isn’t indestructible. It’s fine for a garage shelf or truck, but the latch isn’t heavy-duty. Don’t expect it to survive being run over.

Who Should Buy This

Buy it if you’re a DIYer doing a bathroom remodel, adding a utility sink, replacing CPVC with PEX, or building a manifold system. The mix of sizes and materials means one order covers most residential jobs.

Skip it if you’re a professional who needs specific fitting types in bulk — you’ll want to buy 50-packs of exactly what you use, not a variety kit. Also skip if you’re doing a whole-house repipe with 1-inch mains; you’ll need more fittings than this provides.

FAQ

Q: Do these work with PEX-A (expansion) or only crimp? A: The stainless rings are cinch-style, so they work with PEX-A, B, and C pipe using a cinch tool. The brass fittings work with any crimp system. These are not expansion-style fittings — you won’t need an expansion tool.

Q: Are the brass fittings lead-free? A: Yes, they’re certified lead-free and safe for potable water. If you’re doing a kitchen or bathroom line, you’re covered.

Q: Can I mix these with fittings from other brands? A: Yes. PEX fittings are standardized — these mate fine with SharkBite, Uponor, or any major brand’s PEX pipe. The threaded adapters also work with standard NPT plumbing fittings.

The Verdict

Rating: 4.6/5

The SUNGATOR Mixed Set earns its rating through practicality. It’s not the cheapest kit per fitting, and it’s not the most premium — but it’s the right balance of quality, variety, and organization for the home renovator. The brass machining is clean, the stainless rings hold pressure, and the case actually keeps your workspace organized.

Buy it if you want one order to cover a full residential PEX project without hunting for missing pieces. Skip it if you need bulk quantities of specific fittings or already own a collection of loose parts.

For the DIY plumber who wants to finish the job in one weekend instead of three store runs, this is the kit to grab.
