The SYMMONS INDUSTRIES TT-11-200 is a casing gasket designed to provide a secure, leak-resistant seal within plumbing valve assemblies. Gaskets of this type serve as critical sealing components, preventing water bypass between mating surfaces inside valve bodies or trim housings. The TT-11-200 is installed by licensed plumbers and journeymen during valve service, rebuild, or replacement procedures on commercial and residential plumbing systems. Proper sealing at the casing interface is essential for maintaining system pressure integrity and preventing water damage at the valve location.
This casing gasket is suited for use in repair and maintenance applications where the original gasket has worn, compressed, or otherwise failed to maintain an adequate seal. It is typically installed during a full valve service or trim replacement procedure. Plumbing professionals servicing Symmons valve assemblies will find this part appropriate for restoring proper sealing function to the casing joint.
Designed as an OEM-style replacement casing gasket for compatible Symmons Industries valve assemblies. Verify fitment against the original valve model and trim series before installation.
Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and IPC guidelines. Shut off the water supply and relieve system pressure completely before disassembling the valve casing. Inspect mating sealing surfaces for scoring or debris before seating the new gasket, and avoid over-compressing the gasket during reassembly to prevent premature failure.
