Hayward W400BBKP Vac-Lock Fitting Kit - Black

What This Part Is Used For
The Hayward W400BBKP is a Vac-Lock fitting kit used to create a secure vacuum hose connection at a dedicated wall vacuum port or compatible suction fitting. It provides a stable connection point for suction cleaning through the pool’s circulation system. This version is listed in black for matching darker fittings and finishes.

Why This Part Matters
A poor vacuum port connection pulls air and causes weak suction and frequent loss of prime. A secure Vac-Lock style fitting helps keep cleaning performance consistent. If the existing fitting is cracked or worn, it can leak air and become difficult to use. Replacing the kit restores a tight seal and reliable hose engagement.
