I’ve been deep into PCP air rifles for years now, and if there’s one thing I’ve learned, it’s that a good air fitting can make or break your setup. A small air leak can mean wasted air, lost pressure, and frustrating refills. So, I always keep a few spares of almost everything just in case. I needed an extra set of quick-disconnect fill adapters and decided to give these a shot. The price was reasonable, and the specs - 3000 PSI rated with a max of 4500 PSI - seemed right for my needs. When I finally got them in my hands, the machining quality was apparent. The black zinc-plated copper construction not only looks solid but feels durable in hand. No rough edges, no burrs, and the threading was clean. I installed one onto my air hose in seconds, and the 8mm quick-disconnect fitting snapped in place securely. There was no wobble or play, which I’ve experienced with some cheaper fittings in the past. I ran a pressure test, filling my air rifle to 3000 PSI and checking for leaks. No bubbles in a soapy water test, and after letting it sit for 24 hours, the pressure gauge held steady with zero loss. After several uses, I can confidently say these adapters do exactly what they should - connect quickly, seal properly, and hold pressure without any issues. They are compact enough that they don’t get in the way when handling the fill hose, and they engage with a firm snap every time. The only minor thing I noticed was that the black zinc finish shows slight wear after repeated connections, but that’s purely cosmetic and doesn’t affect functionality. Overall, this was a solid purchase, and I wouldn’t hesitate to get another pair when I need more spares. If you’re running a PCP setup and want a reliable quick-disconnect fitting that won’t leak under pressure, these are a solid choice.Bottom line:These quick-disconnect fill adapters for PCP air rifles are well-machined, durable, and hold pressure flawlessly. Rated for up to 4500 PSI, they install easily, snap securely in place, and show no leaks even after extended use. The black zinc finish wears slightly over time, but that’s purely cosmetic. A solid, reliable choice for any PCP setup. Definitely 5 stars in my book, highly recommended!Pros:1. Well-machined with clean threading and no rough edges.2. Secure, wobble-free quick-disconnect mechanism.3. Rated up to 4500 PSI with excellent pressure retention.4. No leaks, even after extended use and testing.5. Compact design that doesn’t interfere with handling.Cons:1. Black zinc finish shows slight wear over time (purely cosmetic).2. Slightly more expensive than some budget options.

I got these as spares for several PCPs that I have that use them. After a visual look to check machining quality, I installed one simply as a test. It installed easily, accepted the compressor QD with a brisk snap, and held a 3000 PSIG charge with no bubbles noted in a soak test and no observable pressure loss over 24 hours. I'm very pleased with these.
