The GERBER g0091150 is a clamp-on head gasket designed to create a watertight seal in bath drain assemblies. This overflow gasket seats between the drain body and the tub surface, preventing water intrusion beneath the tub and behind the drain fitting. Manufactured from durable rubber, the gasket maintains flexibility and compression resistance over extended service life. It measures 6 inches wide, 4.1 inches long, and 0.85 inches in height, making it a direct-fit option for clamp-style drain installations. Licensed plumbers and experienced service technicians install this part in both residential and light commercial settings.
The g0091150 is suited for clamp-style tub drain applications where a reliable overflow gasket is required. It is intended as a replacement part in bath drain systems and is compatible with Gerber drain configurations as well as other similarly dimensioned fittings. Typical use cases include restoring a failed or degraded seal during a drain assembly service or tub installation project.
Designed for use with Gerber clamp-style drain systems and other bath drain assemblies of similar sizing. Intended as an OEM-style replacement overflow gasket for standard tub drain configurations.
Installation is performed by a licensed plumber or qualified service technician. Shut off water supply and drain the tub completely before beginning any drain assembly service. Ensure the mating surfaces on the drain body and tub are clean and free of debris before seating the gasket. Do not overtighten the clamp retainer, as this can deform the gasket and compromise the seal.
