What This Part Is Used For
The Hayward VLX4005A is a filter accessory kit used on compatible Hayward VL Series sand filter systems. It supports servicing the filter and restoring proper operation after routine maintenance or a teardown. This kit is used at the equipment pad on the filtration side of the system.

Why This Part Matters
When accessory parts are missing or worn, filters can leak, lose sealing, or become difficult to service cleanly. That can lead to messy pads, air intrusion, and inconsistent filtration performance.
