Replace your valve cap with the TRiB airCap Pressure Gauge, a solar-powered, high accuracy gauge built into a valve cap. Maintaining the recommended pressure in your IKs and SUPs ensures optimal performance, with the airCAP you'll always be aware of your craft's pressure up to 20 psi.  Trib AirCaps are great for diagnosing slow leaks in inflatables and for confirming repairs are not leaking.

• High-visibility, easy-to-read LCD displays pressure to one-hundredth of a psi.
• Performs in low-light at dusk, dawn and by headlamp.
• Works battery-free with an efficient solar-powered operation.
• Rugged and fully sealed construction, the airCAP is water resistant and submersible.
• It measures up to 20 psi and is available in two different versions: airCap LF for Leafield C7/D7 valves and airCap HR for Halkey-Roberts, Summit2 and most 1/4-turn valve styles.
• Make-before-break double seal prevents air from escaping during installation.
• Easy installation. Simply remove the factory cap by popping off the lanyard around the valve using pliers and/or a flathead screwdriver. Push the similarly styled lanyard of the airCAP around the ridges on the valve. Screw on and tighten as before.
