Picking the right adapter, answered straight.
My hose feels loose on the filter. Will a new adapter help?
A hose that is too big for its barb will not seal, no matter how hard you push it on. Our adapters cut a barb to your exact hose size, so it seats snug instead of spinning loose. Push each end on by hand until it is fully seated. Use a hose clamp where your setup calls for one. Then check the joint once you fill the tank.
How do I know which adapter size to order?
Pick by your filter model. Our hose guide lists every model's size, and the adapter matches that size. Adapters key on the hose size, not the brand name on the filter.
Do I need glue to install an adapter?
No. Every adapter is a push on fit for the hose or pipe size it lists. You do not need glue.
What if I need a bend instead of a straight run?
Some of our adapters are cut at a 45 degree angle for a gentle bend. For a full 90 degree turn, see our elbow adapters instead.
Can one adapter step down from a bigger hose to a smaller one?
Yes. Many of our adapters connect two different sizes, with one hose or pipe size on each end. Both sizes are listed on the product page.
