Used Electric Pump & one of its adaptors to fit this Pumps/Unpumps up your Paddle board in a few minutes...then use Hand pump to add finishing pressure. Exactly what you needed to make an adapter for your Paddle. Attached it to the pump no problem, Clicks nicely into the paddle board.It was definitely very helpful.
Works well for blowing up a kayak and race w/ an electric pump. Tight fit and seems great quality.
This H-R adapter fits HR valves perfectly and seems like it is well made. Good tight fit in a 3/4" ID Nylon hose. Use this to adapt an electric inflator pump to do most of the inflating work for inflatable SUP, pontoon raft, dinghy, inflatable kayak, inflatable boat, inflatable paddle board, inflatable gymnastic mat, inflatable dock, inflatable water trampoline, airtracks. This adaptor would not depress the valve on the kayak (necessary to fill) without modifying the adaptor. I drilled a 1/8th inch hole and inserted a 1/8" rod so that the gasket covers it. Work fine. Probably is great for most HR applications, but wanted other more owners to know.
This one fits but what You may need to do was remove the rubber washer and then get it attached to your hose solid so that you have a good grip. It may be tight, but put a touch of light oil or even spit on the end of the valve and it will lock in. It did not leak as You inflated the pontoons wither!
Ordering this, gave you a better replacement and spare to tuck in the electric pump bag.
