BULKHEAD KIT 3IN

The Hayward “Bulkhead Kit 3 in” is a plumbing component kit used in pool and spa systems to create a watertight passage where a pipe passes through a tank wall, filter housing, or equipment enclosure. The kit typically includes the bulkhead fitting body, a gasket (or O‑ring), and sometimes the necessary coupling or pipe section for installation. When properly assembled — inserting the fitting through the wall, compressing the gasket with the nut, and sealing the connection — it ensures that water can flow in or out without leaking at the penetration point. This makes the kit essential for connecting internal plumbing (like return lines or filter plumbing) to tanks or housings in a way that’s secure, pressure‑resistant, and long‑lasting under spa/pool conditions.
