The updated H4 Inflate/Deflate Valve is fully compatible with the H3 Valve, found on some older STAR inflatables and on other manufacturers' inflatables.
- The H4 Valve and cap are fully compatible with all components of the H3 Valve.
- The working parts are in the outer portion of the valve, making it easy to clean the valve seal.
- The valve's inner portion is totally enclosed, with fine holes that help block any debris inside the inflation chamber from getting into the valve seal.
- H4 high-pressure valves and caps are replaceable, reliable and airtight.
- The New Short Halkey-Roberts Fill Adapter, # 38501.01, and Halkey-Roberts Valve Wrench, # 38547.01, will work with this valve.
