The VALUE COLLECTION TEV80123 is a Dash 123 PTFE-encapsulated Viton O-ring designed for demanding sealing applications in plumbing, HVAC, and industrial fluid systems. It measures 1.188 inches inside diameter and 1.375 inches outside diameter, with a 0.094-inch cross-section thickness. The FEP encapsulation fully encloses a Viton or silicone elastomer core, combining the chemical resistance of solid PTFE with the elasticity and recovery of Viton. The result is a seamless, uniform seal suitable for aggressive media and wide temperature ranges. Licensed trades including plumbers and HVAC technicians install this type of O-ring in valve assemblies, fittings, and fluid-handling components where standard rubber seals would degrade.
This O-ring is suited for residential and commercial applications where exposure to chemicals, solvents, or extreme temperatures rules out standard nitrile or EPDM seals. Typical install scenarios include pump seals, ball valve seats, refrigeration service fittings, and chemical-handling connections. The Dash 123 designation is a standard AN/SAE size callout used across multiple industries, making this a common cross-reference size for MRO and service replacement work. It is sold individually with a minimum order quantity of one.
Designed as a standard Dash 123 O-ring replacement for valve assemblies, pump seals, and fluid-handling fittings requiring PTFE-level chemical resistance and broad temperature tolerance.
Installation is performed by licensed plumbers, HVAC technicians, or qualified maintenance personnel. Shut off and depressurize the system fully before removing the existing O-ring and inspect the groove for damage or debris before seating the new seal. Avoid using petroleum-based lubricants with PTFE-encapsulated O-rings; use a compatible assembly lubricant if needed. Follow all applicable IPC or IFGC codes for the system being serviced.
