ABSTRACT:
A system for sealing a pool or spa fitting includes a wall having a frustoconical hole therethrough, the hole expanding towards the outer side of the wall. A conduit or inlet fitting is disposed in the hole and has an integrally formed enlarged end portion which abuts the inner surface of the wall. The fitting also has an externally threaded portion opposite the enlarged end, and a nut is threadably disposed on the fitting. A resilient, rubber seal such as a V-gasket or O-ring is disposed interjacent the fitting, the nut, and the surface of the hole. This construction ensures a positive seal of the spa or pool fluid system, while being of substantially simpler and less expensive construction than prior sealing systems.
