Hayward Bulkhead O-Ring for ProSeries Sand Filters W3S210S W3S310S | SX360Z1

Description

The Hayward Bulkhead O-Ring (SX360Z1) is the OEM replacement bulkhead sealing O-ring for Hayward ProSeries sand filters.

IMPORTANT: LUBRICATION REQUIRED — SOLD SEPARATELY
Always lubricate this O-ring with a silicone-based lubricant before installation. Browse our Pool Plumbing Lubricants for a compatible silicone lubricant.

This O-ring seals the bulkhead fitting on ProSeries sand filter tanks, preventing leaks at the point where the plumbing connection passes through the filter body. Replacing a worn, cracked, or flattened bulkhead O-ring restores a watertight seal and stops water loss at the filter tank connection.

Fits Into

Compatibility is based on Hayward parts documentation and available OEM records. This is not an exhaustive list. For certainty, verify the part number in your equipment’s manual or on the original part itself before ordering.

Poolaroo Pro Tip

Before fitting the new O-ring, clean the bulkhead groove thoroughly to remove any debris or remnants of the old O-ring. Apply a thin, even coat of a silicone-based lubricant — never petroleum-based products, which degrade rubber — to help the O-ring seat correctly and extend its service life. Find a suitable lubricant in our Pool Plumbing Lubricants collection.
