For fittings and q.d.'s, you want 90 durometer o-rings. Most else takes 70 durometer. Durometer is the hardness.
Some q.d. manufacturers offer rebuild kits for their product. The Snap-tite 72 series is ISO-B. Any ISO-B rebuild kit from any manufacturer will rebuild your Snap-tite q.d.'s. You do want to check the male end. If the ridge where it grabs the balls is worn, it won't seal. You have to replace the male end, possibly both. |
I need to buy a good caliper for measuring that stuff. Put it off for so long but prices are so low now it's crazy to not have one or more.
I had looked for rebuild kits but never found them, knowing they're out there guess I need to look again so I can be ready.
