Value Collection TES70015 O-ring Dash 015 Ptfe Silicone

Product Description

The VALUE COLLECTION TES70015 is a Dash 015 O-ring with a polytetrafluoroethylene-encapsulated silicone core, designed for sealing applications where both chemical resistance and elastomeric recovery are required. The PTFE-FEP encapsulation completely encloses the silicone core, combining the chemical and temperature resistance of solid PTFE with the flexibility and compression set recovery of silicone elastomer. With a hardness rating of 70 and a seamless, uniform encapsulation layer, this O-ring maintains a reliable seal across a wide service temperature range of -75 degrees F to 400 degrees F. It is sold individually and suited for industrial, fluid handling, and mechanical assembly applications.

This O-ring is appropriate for use in plumbing, HVAC, chemical processing, and food-grade adjacent fluid systems where standard elastomer O-rings fail due to chemical attack or temperature extremes. The PTFE encapsulation provides resistance to aggressive media including solvents, fuels, and caustic fluids. It is a direct-fit replacement for Dash 015 O-rings in any application requiring a round cross-section seal at this dimensional envelope. Licensed tradespeople and assembly technicians working on process piping, valve bodies, pump housings, and fittings commonly install this size.

Key Features

• PTFE-FEP encapsulation provides chemical resistance matching solid PTFE O-rings
• Silicone core delivers elasticity and compression recovery not available with solid PTFE
• Seamless and uniform encapsulation eliminates weak points or seam leaks
• Wide service temperature range: -75 degrees F to 400 degrees F
• Round cross-section conforms to standard Dash 015 groove dimensions
• Hardness of 70 suitable for hard-seating valve and fitting applications

Compatibility

Designed as a direct-fit replacement for Dash 015 O-rings requiring PTFE-encapsulated silicone construction in round cross-section groove profiles across industrial, plumbing, and fluid-handling assemblies.

Installation Notes

Shut off fluid supply and depressurize the system before replacing any O-ring in a pressurized assembly. Clean the mating groove thoroughly and inspect for damage or corrosion before installing the new O-ring. Avoid using sharp tools that could nick the PTFE encapsulation layer, as any breach compromises chemical resistance. Follow applicable plumbing or mechanical codes for pressure ratings and service media when selecting this O-ring for a specific system.
