Not a Compressor Adapter – This head is designed specifically for use with Prestacycle floor pumps and Prestaflator Pro tools only. It does not fit 1/4" air compressor threads. Perfect for All Presta Valves – Safe and compatible with all Presta valve types, including tubeless, tubeless conversions, and modern lightweight performance valves. Durable Urethane Gasket Technology – Features an advanced Urethane Elastomer gasket that lasts 5x longer than rubber, provides a tighter seal, and flexes to fit anywhere along the valve. Fast & Secure Valve Engagement – Push-on / pull-off operation makes inflation quick and easy. Allows high-flow inflation with valve cores removed—ideal for tubeless tire seating. CNC Alloy Construction – Made from lightweight, nickel-plated 6061-T6 aluminum alloy—strong as brass, but only one-third the weight for effortless handling and long-term durability. This head is a MUST for Tubeless tire users. Allows high-flow inflation with the valve core removed for seating tires. Stand outside the wheel and PULL on / PUSH off - the fastest way to get you going. Since our introduction of the improved Quick-Click Presta Head Rubber grommet, the Presta head only goes onto the Presta valve as far as the cap threads. A deep head is no longer needed. This new shorter head has more room to fit into the wheel. It's also compatible with Silca pumps and can be adapted to other pump brands with our optional Schrader barb. Made with 6061-T6 Alloy - Strong as Brass and only 1/3 the weight.
