Value Collection TES70214 O-ring Dash 214 Ptfe Silicone

Product Description

The VALUE COLLECTION TES70214 is a Dash 214 PTFE-encapsulated silicone o-ring designed for sealing applications that demand broad chemical resistance and reliable performance across a wide temperature range. The ring features a 1.0000-inch inside diameter, a 1.2500-inch outside diameter, and a 0.1250-inch cross-sectional thickness. Construction consists of a seamless, uniform FEP (fluorinated ethylene propylene) Teflon encapsulation that completely encloses a silicone elastomer core. This design delivers the chemical and temperature resistance associated with solid PTFE while retaining the elasticity and compression recovery of a standard elastomeric o-ring. Plumbers, HVAC technicians, and industrial service pros use this style of seal in demanding fluid and gas systems.

This o-ring is suited for use in static and dynamic sealing applications where exposure to aggressive chemicals, solvents, or wide temperature swings would degrade standard nitrile or EPDM seals. Typical installations include pumps, valves, fittings, and process piping in chemical, food-processing, and industrial HVAC environments. The Dash 214 designation corresponds to a standardized AS568 size, making cross-referencing straightforward during maintenance and repair work. The round cross-section profile seats consistently in standard o-ring grooves machined to Dash 214 specifications.

Key Features

• FEP Teflon encapsulation fully encloses a silicone elastomer core for dual-material performance
• Operating temperature range: -75 degrees F to 400 degrees F
• Dash 214 standardized size: 1.0000-inch ID, 1.2500-inch OD, 0.1250-inch thickness
• Round cross-section profile for consistent groove seating
• Hard hardness rating (70 Shore) for resistance to extrusion under pressure
• Seamless, uniform encapsulation eliminates weak seams that can allow chemical ingress

Compatibility

Designed as an OEM-style replacement or service o-ring for any application calling for an AS568 Dash 214 size seal in PTFE-encapsulated silicone construction.

Installation Notes

Installation is typically performed by licensed plumbers, HVAC technicians, or industrial mechanics. Shut off and depressurize the system completely before removing the old seal. Inspect the groove for nicks, burrs, or corrosion that could compromise the new seal. Avoid using petroleum-based lubricants with PTFE-encapsulated o-rings; use only a compatible silicone or PTFE-based assembly lubricant if needed.
