The Waterway 400-9157B wall fitting is designed for compatible return applications using a 2-3/8 inch hole size, a 1-1/2 inch female pipe thread by 1-1/2 inch slip connection, and a 3-1/2 inch face diameter in gray. This combination of threaded and slip connection styles makes the fitting especially useful where the surrounding plumbing layout needs added flexibility.

The larger face diameter gives the visible fitting area a more substantial finished presence, while the gray finish offers a balanced look that blends well into many pool and spa surfaces. Using the correct Waterway wall fitting helps restore both the plumbing connection and the appearance of the return point.

For compatible inlet and outlet service work, this Waterway wall fitting is a practical replacement when mixed connection styles and a neutral finish are the right fit.
