Value Collection TEV80122 O-ring Dash 122 Ptfe Viton

Product Description

The VALUE COLLECTION TEV80122 is a Dash 122 O-ring with a polytetrafluoroethylene (PTFE) FEP-encapsulated Viton core, designed for demanding sealing applications across HVAC, plumbing, chemical processing, and industrial fluid systems. The encapsulation is seamless and uniform, fully enclosing a Viton elastomer core to combine the chemical resistance of solid PTFE with the elasticity and compression recovery of Viton. The O-ring measures 1.125 inches inside diameter, 1.313 inches outside diameter, and 0.0937 inches thick, with a round cross section and a hardness rating of 80 Shore. It handles temperatures from -75 degrees F to 400 degrees F, making it suitable for high-temperature and chemically aggressive service environments. Licensed trades including HVAC technicians and plumbers install this seal type in refrigerant lines, pump assemblies, valve stems, and fluid fittings.

This O-ring is appropriate for residential and light commercial applications where standard rubber O-rings fail due to chemical incompatibility or temperature extremes. Common install scenarios include refrigerant service valves, chemical dosing systems, and high-heat plumbing connections. The PTFE encapsulation resists oils, solvents, acids, and most refrigerants, making this a preferred choice when system fluids are aggressive or when regulatory requirements demand a chemically inert sealing surface.

Key Features

• Seamless PTFE FEP encapsulation fully encloses the Viton elastomer core for uniform chemical resistance
• Rated from -75 degrees F to 400 degrees F for wide thermal service range
• Round cross section with 80 Shore hardness for consistent compression and recovery
• Matches chemical and temperature resistance of solid PTFE O-rings while retaining elastomeric sealing force
• Dash 122 standard sizing for drop-in replacement in dimensionally compatible grooves

Compatibility

Designed as a standard Dash 122 O-ring replacement for any groove or fitting calling out that dash size with inside diameter of 1.125 inches and outside diameter of 1.313 inches. Suitable for use wherever PTFE-encapsulated or Viton O-rings are specified.

Installation Notes

Installation should be performed by a qualified technician following applicable codes such as the Uniform Plumbing Code or ASHRAE service guidelines for the specific system. Depressurize and isolate the line or assembly before removing the existing O-ring. Inspect the groove for burrs, corrosion, or damage before seating the new seal. Avoid using petroleum-based lubricants with PTFE or Viton seals; use a compatible assembly lubricant such as a silicone-based or PTFE-rated grease.
