Value Collection TES70125 Ptfe Silicone O-ring Dash 125

Product Description

The VALUE COLLECTION TES70125 is a PTFE-encapsulated silicone O-ring designed for demanding sealing applications where chemical resistance and wide temperature range are required. It features a 1.313-inch inside diameter, a 1.5-inch outside diameter, and a 0.094-inch cross-section thickness with a Dash 125 designation. The construction consists of a seamless, uniform FEP-Teflon outer layer that fully encloses a silicone or Viton elastomer core. This design combines the chemical and temperature resistance of solid PTFE with the elasticity and compression recovery of an elastomeric core. Licensed plumbers, pipefitters, chemical process technicians, and industrial maintenance professionals use this style of O-ring in high-purity and chemically aggressive service environments.

This O-ring is suited for use in fluid handling systems, chemical process piping, food and beverage equipment, pharmaceutical processing lines, and HVAC or refrigeration applications where exposure to aggressive media or wide temperature swings is a concern. The round cross-section profile seats consistently in standard Dash 125 O-ring grooves. Operating temperatures range from -75 degrees F to 400 degrees F, making it viable across a broad range of residential and light industrial system types. It is sold individually and ships as a single unit.

Key Features

• Seamless FEP-Teflon encapsulation fully encloses a silicone or Viton elastomer core for dual-material performance
• Rated for service from -75 degrees F to 400 degrees F
• Dash 125 designation for standard groove compatibility
• Round cross-section shape ensures uniform seating and consistent compression
• Hard hardness rating (70 Shore) for dimensional stability under load
• Combines chemical resistance of solid PTFE with elastomeric recovery properties

Compatibility

Designed as a standard Dash 125 O-ring replacement for any application requiring a 1.313-inch ID by 1.5-inch OD by 0.094-inch cross-section PTFE-encapsulated silicone seal in a round-groove fitting or assembly.

Installation Notes

Installation should be performed by a qualified plumber, pipefitter, or maintenance technician. De-pressurize and drain the system completely before removing the old seal and installing a replacement O-ring. Inspect the groove and mating surfaces for nicks, burrs, or corrosion that could compromise the seal. Avoid twisting or rolling the O-ring during installation to maintain the integrity of the encapsulated construction.
