Waterway Plastics 711-7300 Gasket for Old Faithful Jets

What This Part Is Used For
The Waterway Plastics 711-7300 gasket is a replacement seal used in Old Faithful spa jet assemblies. It installs within the jet body to create a watertight seal between mating components. This gasket helps prevent water from escaping behind the spa wall or into the cabinet area.

Why This Part Matters
A worn or flattened jet gasket is a common cause of slow leaks around spa jets. Left unaddressed, those leaks can lead to cabinet damage, insulation saturation, and recurring water loss. Replacing the gasket restores proper sealing and helps maintain consistent jet pressure and performance. Using the correct part number ensures the jet seats properly and avoids repeat service calls.
