Halkey Roberts (H3) Valve Wrench
P/N: 585209367
I needed to remove the valves on my 15 year old inflatable so that I could squirt sealant into it. I went to the local chain marine store and found a tool that was supposed to work for $3.99. When I went to use it the two protrusions broke right off. This tool does the job. Don't waste your money on any other. Note that I found an aluminum version of the pipe with two protrusions for a higher price. I suspect it would have damaged the valves putting so much pressure on only two places instead of 6.
