Value Collection TES70334 O-ring Dash 334 Ptfe Silicone

Product Description

The VALUE COLLECTION TES70334 is a Dash 334 O-ring designed for sealing applications that demand broad chemical resistance and reliable elasticity across a wide temperature range. It features a seamless, uniform PTFE (polytetrafluoroethylene) FEP encapsulation that completely encloses a silicone elastomer core. This construction delivers the chemical and temperature resistance of solid PTFE while retaining the compression set recovery of a traditional elastomer. With a hardness rating of 70 (hard) and a round cross section, this O-ring suits demanding fluid and gas sealing duties in trade plumbing, HVAC, and industrial piping systems. It is typically installed by licensed plumbers, HVAC technicians, and maintenance mechanics.

This O-ring is suited for static and dynamic sealing applications where exposure to aggressive chemicals, solvents, fuels, or extreme temperatures is a concern. The PTFE-encapsulated silicone construction makes it appropriate for use in pumps, valves, fittings, and flanged connections in commercial and industrial environments. Its temperature range of -75 degrees F to 400 degrees F covers most HVAC and plumbing service conditions. The part is sold individually and is available in single-unit quantities, making it practical for service and repair work.

Key Features

• PTFE FEP encapsulation provides chemical resistance equivalent to solid PTFE O-rings
• Silicone elastomer core delivers elasticity and compression set recovery not available with solid PTFE
• Operating temperature range: -75 degrees F to 400 degrees F
• Seamless and uniform encapsulation prevents fluid ingress to the core material
• Round cross section with 70 hardness (hard) rating for consistent sealing load
• Dash 334 standard sizing ensures dimensional interchangeability with other Dash 334 O-rings

Compatibility

Designed as an OEM-style replacement or service O-ring for any application requiring a Dash 334 cross-section O-ring in PTFE-encapsulated silicone construction.

Installation Notes

Power down or depressurize the system fully before removing or installing O-rings in pressurized fluid or gas lines. Clean the mating groove of debris and inspect for scoring before seating the new O-ring. Avoid twisting or stretching the O-ring during installation, as this can compromise the FEP encapsulation layer. Follow applicable plumbing or mechanical codes, such as the IPC or applicable ASME standards, for sealed joint requirements in your jurisdiction.
