2Pcs Inflatable Boat SUP Pump Adapter, Premium Conventional Air Adapter, Sturdy SUP Air Adapter,Quickly Inflation and Strong Sealing Pump Adapter, for Inflatable Boat, Paddleboard and Kayak

It fits both brands of paddle boards with HR valves we own, and makes using our DeWlt inflator a better less sweaty experience inflating 4 boards. Rubber gasket is a little stiff, but should last nicely. Good value, no leaks noticed pumping up to 13psi. The black portion is not glued or attached to the grey part, and when twisting into a board can slip and be difficult to get sealed. A few drops of super glue, works great, so consider buying a little tube of glue with these, makes twisting the adapter into the valve so much easier! Would buy again, but they send you two so props won’t have to

Decent quality. We have multiple boards and this has saved some time. I have on board air on my jeep and these do the trick to inflate multiple boards at the same time. Performance will depend on your compressor, as this is just an adapter. Be careful not to over-inflate. Fit seems fine, just make sure the valve is closed before attaching. Also, detach air hose before removing from paddle board, so the Schrader valve can close. So far, seems worth the money.

These are perfectly functional with no issues. They fit perfectly, don't leak while filling, the valve fits the pump connectors, and the build quality is everything you'd hope for. These are not used as my primary method for filling my SUPs, but they are great to have on hand for emergencies or when the need arises. Please do remember to remove this once the paddleboard is full. You certainly wouldn't want to fall on it, as it could leave a nasty scratch.

Works pretty well with the air compressor at home to get my paddle boards filled up 95% of the way. I still use my manual pump for the very end to make sure I inflate my boards to the correct psi.

First time trying to use them the brass part pushed in, as you can see on the one on top in the attached photo. Both did this, but I used pliers to pull one back out for comparison. I wasn't pushing over hard or anything, just normal pressure needed to get the air chuck to work. They are unusable. Buy these instead https://www.amazon.com/dp/B0DF7WMM4Z I did and they are much better.

Quality is good, bought them for my paddle board. Did not have to use them, but glad I have them

My son bought a Water Skeeter float tube fishing rig, and on his first outing it took 150 pumps of the foot operated foot pump to inflate just one of the two tubes for the float rig. That took a very long time to get both float tubes inflated and the rig assembled and to the water for launch. I bought these adapters to allow me to use my battery powered leaf blower to quickly inflate the float tubes to low pressure, and then to use the original foot pump to raise the float tube pressure to the required psi to keep the floats rigid. I haven't used them as of yet, but when I get to try them out I will update this review. One video I watched of a guy inflating his floats with his leaf blower only took him a minute for each float tube to get it totally inflated so that he could finish off the higher inflation pressure with his foot pump. Much faster and easier to do... Deflating them using the battery leaf blower in sucker mode will make deflating the floats much faster too. Stay tuned....

Fits the paddle boards well, hooks up to a tire pump with ease and allows you to inflate faster than by hand. Very durable have just thrown in the gear bag getting smashed around. Cheap solution and works as it should.

Worked very well with my Ryobi Air pump, made Paddle board inflating a breeze. Seem to be well made and fit without any leaks.

Perfect quality and compatibility

Works as expected.

Works really well

They are totally useless. Maybe because the wrong size. I adjusted the valve height and even take out the core of the valve, still no air pumped into the SUP board.
