Free tube to 1st taker...
Kaplain tube hardly used.
Nearly 9 & 1/4 inches to the air valve with an I.D. of 2 & 1/4”.. 1st one I bought and it ended up being to narrow and couldn’t fit the last three or so inches into it without cramming it in which defeats the purpose of pumping.. It cost me 50 some bucks but I’m willing to give it away to the first taker…
