Value Collection TEV80020 O-ring Dash 020 Ptfe Viton

Product Description

The VALUE COLLECTION TEV80020 is a Dash 020 O-ring with a polytetrafluoroethylene (PTFE) FEP-encapsulated Viton core. It measures 0.875 inches inside diameter, 1.000 inches outside diameter, and 0.0625 inches thick with a round cross section. The seamless Teflon FEP encapsulation fully encloses a Viton elastomer core, delivering the chemical and temperature resistance of solid PTFE while retaining the elasticity and recovery properties of Viton. This combination makes it well suited for demanding fluid-handling, sealing, and chemical-process applications. Plumbers, HVAC technicians, and industrial service technicians install this type of O-ring during routine maintenance and component rebuilds.

This O-ring fits sealing applications that require resistance to aggressive chemicals, fuels, solvents, and wide temperature swings from -75 degrees F to 400 degrees F. It is commonly used in valve bodies, pump assemblies, fittings, and fluid-system connections where standard rubber O-rings would degrade. The round cross-section profile seats cleanly into standard Dash 020 O-ring grooves found across plumbing, HVAC, and light industrial equipment.

Key Features

• PTFE FEP encapsulation provides the chemical resistance of solid PTFE with Viton elastomer recovery
• Operating temperature range: -75 degrees F to 400 degrees F
• Seamless and uniform encapsulation completely encloses the Viton core
• Round cross-section profile for reliable seating in standard Dash 020 grooves
• Hard hardness rating (80 Shore) resists extrusion under pressure
• Sold individually — single-piece packaging, MOQ of 1

Compatibility

Designed as a replacement or service O-ring for any application specifying a Dash 020 O-ring with PTFE-encapsulated Viton material and a round cross section.

Installation Notes

Installation is typically performed by licensed plumbers, HVAC technicians, or qualified industrial mechanics during valve, pump, or fitting service. Always depressurize and drain the system before replacing any O-ring seal. Inspect the mating groove for nicks, scoring, or debris that could compromise the seal. No lubrication should be applied without verifying compatibility with PTFE-encapsulated materials, as some lubricants attack the Viton core.
