Picking the right adapter, answered straight.
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.
Will an adapter fit rigid PVC pipe, not just flexible hose?
Some sizes are cut for PVC pipe as well as hose. The product page names the pipe size each one takes.
