Pentair 152517 O-Ring - 158mm x 4mm, NBR 70A

What This Part Is Used For
The Pentair 152517 O-Ring is used in equipment assemblies requiring a 158mm x 4mm seal made from NBR 70A material. It creates a secure seal under operating pressure.

Why This Part Matters
A failed seal can introduce air or allow water to escape from the system. That reduces filtration efficiency and can strain pumps. Replacing the O-ring restores proper sealing and stable performance.
