Hayward VLX4002A Clamp Hardware and Filter O-Ring Kit

What This Part Is Used For
The Hayward VLX4002A is a clamp hardware and filter O-ring kit for compatible Hayward VL Series sand filters. It supports securing the filter body and maintaining the seal at the filter joint. This kit is used on the equipment pad during filter service or clamp replacement.

Why This Part Matters
A worn clamp or flattened O-ring can cause leaks at the filter seam and make the system hard to keep sealed. If the clamp hardware is compromised, the filter may not hold pressure reliably and service becomes unsafe and messy. Replacing the clamp hardware and seal together restores proper closure and reduces repeat leaks. Correct parts help prevent overtightening that can damage the filter body.
