Value Collection TES70216 O-ring Dash 216 Ptfe Silicone

Product Description

The VALUE COLLECTION TES70216 is a Dash 216 O-ring built with a polytetrafluoroethylene (PTFE) FEP encapsulation over a silicone elastomer core. This seamless, uniform encapsulation completely encloses the core material, combining the chemical and temperature resistance of solid PTFE with the elasticity and recovery characteristics of silicone rubber. The round cross-section profile measures 1.125 inches inside diameter, 1.375 inches outside diameter, and 0.125 inches thick. With a rated hardness of 70 Shore and an operating range of -75 degrees F to 400 degrees F, this O-ring is suited for demanding fluid and gas sealing applications in plumbing, chemical, and process piping systems.

This O-ring is used in residential and commercial applications where standard elastomer seals would degrade due to aggressive chemicals, solvents, or elevated temperatures. Typical install scenarios include pump housings, valve stems, flanged connections, and fluid handling equipment where PTFE-level chemical compatibility is required but a compliant, resilient seal is also needed. Plumbers, pipefitters, and maintenance technicians working on process systems are the primary installers of this seal type.

Key Features

• Seamless PTFE FEP encapsulation over a silicone elastomer core for dual-material performance
• Operating temperature range of -75 degrees F to 400 degrees F
• Round cross-section, Dash 216 standard sizing for drop-in replacement fitment
• 70 Shore hardness rated Hard for positive sealing under compression
• Combines PTFE chemical resistance with silicone elasticity and recovery
• Black color for visual identification during installation and inspection

Compatibility

Designed as an OEM-style replacement or upgrade seal for Dash 216 O-ring grooves in plumbing, valve, pump, and fluid-handling assemblies requiring PTFE-encapsulated silicone seals.

Installation Notes

Installation should be performed by a licensed plumber or qualified pipefitter. Shut off and depressurize the system completely before removing the existing seal or disassembling any fittings. Inspect the O-ring groove for burrs or contamination before seating the new seal, and avoid using sharp tools that could puncture or nick the PTFE encapsulation. Follow applicable IPC or IFGC code requirements for the system being serviced.
