Kwik Tek Airhead Boston Valve, Red, One Size (AHBV-2), 2 Count (Pack of 1)

love these! fits snug like a bug in a rug :D plus the color makes it so easy to find! the valve on the inside works like a charm too! lifehack: inflate it as much as you can with a hairdryer on cool setting. If your hair dryer is strong enough, just unscrew the top part of the cap and use the hair dryer to inflate it fully. If your hair dryer is not blowing a strong stream of air out. just inflate it as much as you can without the red cap and quickly slap that baby on before all the air comes out. After that, just unscrew the top bit and inflate the rest of it by mouth. i managed to fully inflate mine with just 10 big huffs. Sleepovers have never been so easy :D

I took a chance that these would fit my Zpro Tango 200 boat, and luckily they did. I haven't voyage-tested them yet, but they worked fine on an inflation test on land.

Bought this to replace the 2.5 cm missing valve of a Bestway inflatable matrice double. The larger valve fits perfectely .And being red is less likely to get lost !

my son bought a boat from display and did not use it for a long while and then found the valves were missing so he was going to throw it away. I found these on the web and are great.

I ordered these for my ten year old Plastimo Dingy and chose the wrong size. But managed to use an adaptor and it works great. There should be a lot more details about the dimensions of these valives provided to help selection. I am pleased with my choice

good working product,thanks

Fitted my air bed valve well, as lost original screw cap.

Okay, first off bought these from Boatworld who are great - super fast despatch and delivery (in my hand within two days of ordering). I trawled the internet to find a replacement valve for my Anker International "Anker II" inflatable dinghy which has been in the loft for ten years! All I had was the diameter of the internal part of the bore/hole (2.5cm).......that's it. I read the different reviews for lots of products and after reading about the Boston valve and more particularly the pack of two different sizes, after seeing the "one is sure to fit" claim, I decided to gamble. The pack arrived (very quickly) and the first thing I noticed is the diameter of the valves appeared to be identical despite what other reviewers have stated. I tried them both in my dinghy and they both fit perfectly.......which confused me somewhat, as again the thread pattern appears to be identical. The only discernible difference to me is that one "shaft" (the bottom threaded protrusion) is longer than the other. My dinghy has been inflated for over a day now and no air leakage.I'm happy, now I can go paddling on the lake again. So overall a great result for me, not only did it fit, I have a spare too, maybe not so great for the person who has high hopes of there being two different fittings though.........
