Lezyne ABS Flip Chuck

The ABS Flip Chuck is designed as a direct replacement for Lezyne's High-Pressure Floor Drive floor pumps and Micro Floor Drive hand pumps. If you own one of these models, it will thread directly onto your existing hose.

The chuck features a reversible internal fitting. You simply unscrew the cap, flip the internal rubber seal to match either Presta or Schrader, and screw the cap back on to secure it for your specific valve type.

The air bleed button allows you to micro-adjust your tire pressure without disconnecting the pump from the valve. It is particularly useful if you accidentally over-inflate your tire and need to release a small amount of air to hit your target PSI.

This chuck is specifically engineered for Lezyne's proprietary hose threading. While it may physically fit other hoses with the same thread pitch, it is optimized for Lezyne pump systems and we recommend it primarily for those units.

No tools are required. You can easily unscrew your old chuck by hand and thread the new ABS Flip Chuck onto the hose. Just ensure it is tightened securely to prevent air leaks during inflation.
