Product History & Overview

The Hayward HCF Series revolutionized commercial pool filtration with high-capacity, durable filters engineered for efficiency and ease of maintenance. The 3" Union O-Ring is a crucial sealing component designed to fit union connections in these systems, ensuring watertight connections and preventing leaks despite exposure to harsh pool chemicals and varying pressures.

Installation Tips & Tricks

• Power down all pool equipment and close valves before beginning any maintenance.

• Carefully remove the old O-ring to avoid damaging the union housing.

• Clean the O-ring groove and surrounding surfaces to remove residue and debris.

• Apply a light coat of silicone-based lubricant approved for pool use on the new O-ring to enhance flexibility and seal quality.

• Avoid stretching or twisting the O-ring during installation to prevent damage.

• Hand-tighten unions, then use a strap wrench if needed—do not overtighten to prevent cracking.

• Gradually restore water pressure and inspect the union connection for leaks.

Electrical Safety Information

• While this O-ring is a non-electrical component, always ensure all pool equipment power is shut off and properly grounded before maintenance.

• Verify that pumps, automation systems, and control panels comply with local electrical and NEC bonding codes.

• Use appropriate safety gear and follow safe practices when working near energized components.
