Description

A 1‑inch nominal bulkhead fitting is designed to allow a pipe or fitting to pass through a wall or tank, creating a sealed transition. It consists of a threaded body, a nut, and a gasket or washer to seal it against the wall or barrier so that fluids can flow without leaking. The “1″” size refers to the nominal pipe size the bulkhead accommodates. Bulkhead fittings are used in aquariums, tanks, rain barrels, plumbing walls, and other applications where a watertight or airtight barrier‑penetration connection is needed. For proper installation, it’s important to use the correct gasket placement (usually on the flange side), drill the correct sized hole, and avoid over‑tightening the nut to prevent cracking the tank or compromising the seal.
