1.5″ Union O-Ring

The 1.5″ Union O-Ring is a flexible sealing ring designed specifically for 1.5″ union fittings in hot tubs and spa pipework. Providing a leak-proof seal between union halves, this O-ring ensures water stays contained under pressure and helps maintain system performance.

Replacing worn union O-rings is part of good spa maintenance, helping to prevent leaks and maintain reliable plumbing integrity.
