Pond Fittings » Bulk Head Fittings » Bulk Head Fittings

Very hard to find! These fittings are designed to go through the walls of filters and ponds, making additional jets and pond returns a reality without worrying about leaks.

Thru-tank adapters with gasket and nut. This fitting (pictured to the right) has a 2.5" shaft instead of the standard 1" shaft.

Easy to use with liners to attach pvc flexible and rigid plumbing. A must for plastic or fiberglass bio-filter tanks. Makes plumbing a barrel simple. Available in many sizes.
