Hayward W400BWHP Vac-Lock Fitting Kit - White

What This Part Is Used For
The Hayward W400BWHP is a Vac-Lock fitting kit used to create a secure suction connection point for pool vacuum hoses. It is used at a dedicated wall vacuum port or compatible suction fitting depending on the pool setup. This version is listed in white to match common pool fittings.

Why This Part Matters
A worn or incorrect vacuum fitting can pull air, reduce suction, and make vacuuming frustrating. A secure Vac-Lock style connection helps maintain prime and consistent cleaning performance. If the fitting is cracked or loose, it can lead to recurring suction leaks and weak vacuum. Color matching also matters on finished pools where fittings are visible.
