O-Ring (Union Assembly)

O-Ring for Union Assembly - Replacement Union Seal

Replacement O-ring for pool plumbing union assemblies. This small seal sits inside your pump, filter or equipment unions and creates the watertight joint that lets you disconnect equipment for servicing without cutting pipe. A perished union O-ring is one of the most common causes of small leaks on the equipment pad.

Key Features

• Replacement O-ring for union assemblies
• Restores a watertight, drip-free union joint
• Durable rubber construction for long service life
• Inexpensive essential spare for any pool owner

When to Replace

• Water weeping or dripping from a union joint
• O-ring appears flattened, cracked or pinched
• Every time a union is opened for major servicing
• Air being drawn into the pump suction side through a union

Installation Tip

Clean the union faces before fitting the new O-ring and apply a light coat of silicone-based lubricant. Hand-tighten the union; over-tightening with tools can distort the seal and cause the very leak you are trying to fix.
