Union O-Ring Seal 2" for Spa

The Union 2" sealing o-ring is a replacement part for 2-inch union fittings on spas and water circulation systems. This o-ring seals between the two halves of the union and prevents leaks at the joints. Essential for preventive maintenance and for repairing a residential spa that drips at the connection.

• Format: 2-inch union
• Outside diameter: 2-7/8"

• Width: 3/8"

Compatibility

Designed for standard 2-inch union connections. Measure your old o-ring (inside, outside diameter and thickness) to confirm the match before ordering.

When to replace

Replace the o-ring when it is hardened, cracked, deformed, or whenever the union leaks even when tightened. A new o-ring restores the seal without replacing the whole union.

FAQ

How do I know it's the right o-ring? Compare the inside, outside diameter and thickness with your current seal.

Should the o-ring be lubricated? A silicone-based lubricant eases installation and extends the seal's life.
