Restores the seal at the specified pump joint. The profile, dimensions and installation point must match the original; a similar-looking O-ring may not seal correctly.
Advice from a pool technician
Clean the groove before fitting and ensure the seal is not twisted. Only use lubricant suitable for the seal and recommended by the manufacturer.
When to replace this part
Replace a hardened, cracked, distorted or flattened seal. Inspect the mating surfaces too: a new seal will not repair a cracked housing or damaged thread.
