LEZYNEABS Standard Flip-Thread Chuck HP Pump Head

Works as intended. I added a picture of the flip chuck because the product picture doesn't show the threads on both ends.I bought it because I lost an O-ring on the flip chuck that came with my pump when originally purchased (3 years ago). I used a bit of silicone grease on the outer o-rings and threads to switch the flip chuck smoothly, but I didn't not place any silicone on the o-ring that is inside the presta end.2nd picture is my pump. I have to Classic Floor Drive High Pressure 220psi

Seals tight no leaks. My old chuck was very finicky so I took a chance a new chuck would fix my problems and it did. The old one worked for 10 years and I assume this one will as well. The Lazine steel pump is amazing. Can't go wrong for the price it just can't be surpassed. The Customer service is top notch as well. They sent me a replacement valve at no cost at all. No shipping cost either, shipped from Germany.

Being made of aluminum, this hose nozzle's threads can wear easily, so replacement becomes necessary.

I like Lezyne pumps. I started to have problems using the larger pump that I have had for a number of years. So I tried my smaller version that I carry on my bike and it worked fine. So I ordered a new pump head for the larger pump and that solved the problem. A much cheaper solution that buying a new pump.

I've had Lezyne floor pump for 5+ years- works great, but the chuck got leaky. This totally fixes the issue.

I bought this to replace a worn chuck on a Lezyne floor pump. Great for inflating high pressure presta bicycle tires. Avoid bending delicate presta valve stems. Also, you can release hose pressure before removing chuck. Unfortunately, this chuck will only work with Lezyne pumps. You may however, be able to purchase a complete Lezyne pump hose assembly and convert your non-Lezyne pump using hose clamps to attach the hose to your old pump. BTW, it also works well with Schrader valves -- but you have to reverse the chuck and the pressure release valve can be used to adjust tire pressure before removing chuck.

I bought o rings from McMaster carr to repair my old one, but it just east r the same. For this little money every few years, can’t go wrong for a great pump!

The Lezyne Screw on style chuck works perfect for High PSI tubular tires. This design is the only one that doesn't pop off or leak when using. Yeah... Takes a few sec longer to attach and un-attach... And it's made of Aluminum so the threads don't last forever..
