Waterway Plastics 805-0330 O-Ring - BN50 Shaft #330

What This Part Is Used For
The Waterway Plastics 805-0330 O-Ring is a sealing component used in BN50 motor or pump shaft assemblies. It provides a seal around the shaft interface to limit leakage or air intrusion. This O-Ring is installed internally and works in conjunction with other sealing components. It supports proper mechanical operation of the assembly.

Why This Part Matters
A degraded shaft O-Ring can allow moisture to migrate into sensitive components. This may lead to premature wear, noise, or reduced equipment life. Replacing the O-Ring helps preserve internal alignment and sealing. OEM sizing ensures the correct balance between compression and movement.
