Does anyone know where to buy just the stem/hose part of the airbag? NRS sells the valve, but I cannot find anyplace that sells the plastic stem part. I have a fully functioning airbag with a good base seal, but just need a stem to plug into the base part. Thanks!

You could try calling around to different paddling shops.

You could try your local hardware / home building support store.

You could even post to your local paddling area Facebook group an ISO float bag tubing and ask if anyone has an old leaky float air bag kicking around from which you could take the tubing. (ISO in search of)

You could try an online outfit such as

scroll down to Clear Scratch- and UV-Resistant Acrylic Tubes and see what you think. Probably 1/16" Wall Thick or 1/8" Wall Thick. 3/8 or 1/2 inch

its just clear plastic tubing available many places, including Lowes if it has the right diameter. some bags use a smaller diameter inserted in the base rather than fitting over it which is more common. I have salvaged pieces of the larger diameter, maybe some new, if you can't find it anywhere else. John

I've given up on replacing tubular stems and have found the raft valves which are easily found on the internet and which combine the dump valve and input in one to be a good replacement. Mohawk bags now come like this.
