The Hayward W400BLGP is a Vac-Lock fitting kit used to provide a secure suction connection for pool vacuum hoses. It is used at a dedicated wall vacuum port or compatible suction fitting based on the pool’s plumbing layout. This kit is listed in light gray for matching existing pool fittings.

Why This Part Matters
