Safety
A note on safety
We print every part in PETG. It is the material aquarium keepers have used submerged for years. Rinse each part in clean water before you add it to your tank.
Common questions
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.
