Value Collection TES70113 O-ring Dash 113 Ptfe Silicone

Product Description

The VALUE COLLECTION TES70113 is a Dash 113 O-ring with a polytetrafluoroethylene (PTFE) FEP-encapsulated silicone construction. The seamless Teflon FEP encapsulation fully encloses a silicone elastomer core, combining the chemical and temperature resistance of solid PTFE with the elasticity and recovery of silicone. This round cross-section O-ring measures 0.563 inches inside diameter, 0.750 inches outside diameter, and 0.0937 inches thick. It carries a hardness rating of 70 (hard). Licensed plumbers, HVAC technicians, and industrial maintenance trades install this type of seal where aggressive media or wide temperature swings would degrade standard elastomer rings.

This O-ring is suited for static and dynamic sealing applications across residential and commercial systems where exposure to harsh chemicals, high heat, or cryogenic conditions is a factor. The Dash 113 designation makes it a standard-profile size used in a wide range of fluid-handling, valve, pump, and piping assemblies. Its operating range of -75 degrees F to 400 degrees F makes it appropriate for steam, chemical processing, food-grade equipment, and high-temperature HVAC or plumbing connections where standard nitrile or EPDM compounds fall short.

Key Features

• PTFE FEP encapsulation provides seamless, uniform coverage over the silicone core for superior chemical resistance
• Operating temperature range from -75 degrees F to 400 degrees F suits extreme service environments
• Round cross-section profile conforms to standard Dash 113 O-ring dimensions
• Hardness of 70 (hard rating) supports reliable compression under pressure without excessive deformation
• Matches the elasticity and recovery characteristics of a solid elastomer ring while resisting media that would attack uncoated silicone

Compatibility

Designed as a standard Dash 113 O-ring replacement for valves, pumps, fittings, and fluid-handling assemblies that require a PTFE-encapsulated silicone seal with a 0.563-inch inside diameter and 0.750-inch outside diameter.

Installation Notes

Installation is typically performed by a licensed plumber, HVAC technician, or qualified maintenance mechanic. Always isolate and depressurize the system and shut off fluid supply before removing the existing seal. Inspect the groove and mating surfaces for wear or damage before seating the new O-ring. Avoid over-stretching the ring during installation, as the PTFE encapsulation layer can be compromised by excessive deformation.
