Pump chucks that clamp onto valves work until they don't—one day the lever stops holding pressure, the seal gives out, or the mechanism blows off mid-stroke and sends the hose whipping across the garage. Threaded chucks eliminate that failure mode entirely. Lezyne's ABS-1 Pro Floor Pump Hose comes with the ABS-1 Pro chuck preinstalled, giving you a valve interface that screws onto Presta or Schrader stems for a connection that stays put regardless of pressure. If your current pump hose has developed leaks or the chuck has become unreliable, this replacement brings the whole system back to working order.

The ABS-1 Pro chuck uses a flippable design—unthread the head from the swivel, rotate it 180 degrees, and reattach to switch between valve types. One end threads onto Presta valve cores, the other onto Schrader valve threads. The 90-degree bend positions the hose away from the wheel at a natural angle, reducing stress on both the hose and valve stem during pumping. Machined aluminum and Composite Matrix construction handles years of use, and a brass swivel keeps the connection rotating smoothly without binding.

Beyond the secure threading, the chuck includes features that eliminate separate tools. An integrated Presta valve-core wrench on the back of the head tightens loose cores before inflation or removes them entirely when seating tubeless tires. A bleeder button releases small amounts of air for precise pressure adjustment without disconnecting from the valve. The hose itself uses standard construction compatible with all standard-pressure floor pumps, making it a direct replacement for worn or damaged original equipment.
