These poly bulkhead fittings are ideal when you need a watertight seal when making a penetration under water level. Use for liners, filters, skimmers and other pond components.

The polypropylene outlet flange comes with a female NPT full port, and the polypropylene inside bolt seal double seal flange is full port as well. Highly durable and chemical resistant, our resin is a high strength custom blended glass filled polypropylene.

Features two washers and internal pipe threads on both sides of the bulkhead. These quality bulkheads allow for clean side-wall or bottom penetration of rigid water containment such as preformed filter tanks and preformed ponds. Reverse threaded so they stay tight even when you screw an intake screen onto them.
