This double-action pump (with integrated pressure gauge) is designed for W-Style Boards and Valves.
W-Style boards include:
XTERRA BOARDS' High-pressure pump & gauge - Inflate board to 15 psi using the industry-best high-pressure double-action pump with integrated pressure gauge. Inflation takes 5 minutes for most boards. Our pump is a dual-action so pumping is fast & easy.
