Value Collection TEV80115 O-ring Dash 115 Ptfe-viton

Product Description

The VALUE COLLECTION TEV80115 is a Dash 115 O-ring designed for demanding sealing applications where chemical resistance and wide temperature tolerance are critical. Constructed with a seamless PTFE (polytetrafluoroethylene) FEP encapsulation that completely encloses a Viton or silicone elastomer core, this O-ring delivers the chemical and temperature resistance of solid PTFE while retaining the elasticity and recovery properties of an elastomeric seal. It measures 0.688 inches inside diameter, 0.875 inches outside diameter, and 0.0937 inches thick, with a round cross section and a hardness rating of 80. Licensed tradespeople and maintenance professionals install these in fluid handling, chemical processing, and mechanical systems where standard rubber seals fail.

This O-ring is suited for residential and commercial applications involving aggressive chemical media, high-purity fluid systems, and environments that cycle across a broad temperature range. Typical installation scenarios include pump seals, valve stems, fittings, and plumbing connections where compatibility with harsh solvents, acids, or elevated temperatures is required. The PTFE FEP encapsulation makes it a direct functional alternative to solid PTFE seals in standard Dash 115 groove dimensions.

Key Features

• Seamless, uniform PTFE FEP encapsulation fully encloses a Viton or silicone elastomer core
• Temperature range: -75 degrees F to 400 degrees F
• Round cross section for reliable groove seating and uniform compression
• Hardness rating of 80 (Hard) for positive sealing under pressure
• Combines chemical resistance of solid PTFE with the elasticity of Viton
• Dash 115 standard sizing for drop-in replacement in compatible grooves

Compatibility

Designed as a standard Dash 115 O-ring replacement for grooves requiring PTFE-encapsulated seals with an inside diameter of 0.688 inches and an outside diameter of 0.875 inches.

Installation Notes

Installation is typically performed by licensed plumbers, pipefitters, or mechanical maintenance technicians. Before replacing an O-ring, relieve all system pressure and isolate the fluid supply. Inspect the groove for burrs, scoring, or debris that could compromise the seal. Avoid stretching the encapsulation beyond its elastic limit during installation, as damage to the PTFE jacket will compromise chemical resistance.
