Value Collection TES70325 O-ring Dash 325 Ptfe Silicone

Product Description

The VALUE COLLECTION TES70325 is a Dash 325 O-ring constructed with a polytetrafluoroethylene (PTFE)-encapsulated silicone core. The seamless FEP Teflon encapsulation completely encloses a silicone elastomer core, combining the chemical and temperature resistance of solid PTFE with the elasticity and recovery characteristics of silicone rubber. This O-ring measures 1.5 inches inside diameter, 1.875 inches outside diameter, and 0.1875 inches in cross-section thickness. The round cross-section profile and hard 70-durometer hardness rating make it suitable for static and dynamic sealing applications handled by plumbers, HVAC technicians, and industrial maintenance trades.

This O-ring is used in fluid and gas sealing applications where resistance to aggressive chemicals, wide temperature swings, or both are required. The PTFE encapsulation makes it appropriate for systems handling corrosive media, steam service, or food-adjacent process lines where a standard elastomer O-ring would degrade. Typical install scenarios include pump housings, valve stems, pipe flanges, and fittings in residential and commercial mechanical systems. It is sold as a single piece per package.

Key Features

• PTFE-encapsulated silicone construction combines chemical resistance with elastomeric recovery
• Seamless and uniform FEP Teflon encapsulation fully encloses the silicone core
• Operating temperature range of -75 degrees F to 400 degrees F
• Hard 70-durometer hardness rating for reliable compression sealing
• Round cross-section profile, Dash 325 standard sizing
• Black color; sold as a single unit per package

Compatibility

Designed as a standard Dash 325 O-ring replacement for static and dynamic sealing applications requiring PTFE-encapsulated silicone construction in plumbing, HVAC, and industrial process systems.

Installation Notes

Installation is typically performed by licensed plumbers, HVAC technicians, or industrial maintenance mechanics. Always depressurize and isolate the system before removing the old O-ring and seating the replacement. Inspect the groove and mating surfaces for scoring or contamination before installation. Avoid twisting or rolling the O-ring during installation to prevent damage to the encapsulation layer.
