00:00If your HPA tank is hissing at you every time you fill it, 9 times out of 10 it's not
00:04the
00:04regulator, it's a $2 o-ring that gave up. I went digging through the best-selling
00:09polyurethane seals people actually keep reordering, and pulled the top 5 for air tank seals.
00:15Prices, sizes, the whole thing. Let's get into it.
00:20Starting with the one almost everybody needs first, the AS568-007 polyurethane o-ring in
00:2690 Deerometer. This is the seal that sits on your fill nipple, the one-way foster fitting.
00:32If air puffs out when you disconnect the fill line, this little guy is your culprit.
00:37It's $1.98. Nearly 5,000 sold, straight 5-star rating. Honestly, at that price I'd grab a
00:45couple and toss the spare in your deer bag, because this is the seal that always fails at the field,
00:50never at home. Next up, the bigger piston seal for the tank regulator.
00:56Same 90 Duro polyurethane, but this one goes on the piston itself, so if your reg is creeping,
01:01or the output pressure just won't hold steady, that's usually the piston seal wearing flat.
01:06It's $8.66, and you get a pack of 20 or 50 depending which option you pick.
01:124.7 stars from almost 5,000 buyers. Buying in bulk here makes sense,
01:18since once you've got the reg apart you might as well have spares ready for the next rebuild.
01:23Third is the valve head seal in G1-2-14 Epoly Urethane, 90 Duro, sold as a gasket and washer
01:29set.
01:30This is the seal between your reg body and the tank neck, and when it goes, you get that slow
01:35leak that empties your tank overnight. $8.56 for 20 or 50 pieces, and a perfect 5-star rating across
01:42over 4,500 sales. The G1-2-14 thread is the standard on most HPA bottles, so double-check yours,
01:50but if it matches, this is the one. Fourth, basically the same G1-2-14 valve head seal,
01:57just a different seller and a cheaper pack, $6.42 instead of $8.56. Also 5 stars, nearly 4,000
02:04sold.
02:05Same 90 durometer polyurethane, same washer, and gasket setup. If you're just after the best price
02:12per seal and you don't mind which listing it ships from, this is the value pick of the two.
02:17$2 saved is $2 saved. And rounding out the list, the standalone polyurethane piston seal, 90 Duro.
02:25This one's for you if you don't want a 50-pack sitting in a drawer, you just need the piston
02:29o-ring, once, to fix the reg on your desk right now. $4.10, 4.9 stars, over $3,800
02:37sold.
02:38Small, cheap, does one job well. That's kind of the whole point of an o-ring.
02:44All 5 links are down in the description, so grab whichever one matches your setup.
