Value Collection TEV80228 Dash 228 Ptfe Viton O-ring

Product Description

The VALUE COLLECTION TEV80228 is a Dash 228 PTFE-encapsulated Viton O-ring designed for sealing applications that demand high chemical resistance and wide temperature tolerance. It features a seamless FEP (fluorinated ethylene propylene) Teflon encapsulation over a Viton or silicone elastomer core, combining the chemical resistance of solid PTFE with the elasticity and recovery of an elastomeric O-ring. The round cross-section profile measures 2.25 inches inside diameter, 2.5 inches outside diameter, and 0.125 inches thick. Licensed plumbers, HVAC technicians, and industrial service professionals install this type of seal in systems handling aggressive fluids or extreme temperatures.

This O-ring is suited for use in plumbing, HVAC, chemical processing, and fluid handling systems where standard rubber O-rings fail due to chemical attack or thermal degradation. The Dash 228 designation makes it a standardized size, appropriate for face-seal, groove-mounted, and static sealing applications in both residential and light commercial service environments. It is sold individually and is a direct-replacement seal in any application calling for a Dash 228 PTFE-encapsulated Viton O-ring.

Key Features

• Seamless FEP Teflon encapsulation completely encloses the elastomer core for uniform chemical resistance
• Viton or silicone elastomer core provides elasticity and recovery properties matching solid PTFE performance
• Rated for service from -75 degrees F to 400 degrees F
• Hard durometer rating (Shore 80) for dimensional stability under compression
• Round cross-section for reliable groove seating
• Standardized Dash 228 dimensions ensure broad interchangeability

Compatibility

Designed as a standardized Dash 228 replacement O-ring for any static or face-seal application specifying a 2.25-inch ID PTFE-encapsulated Viton O-ring.

Installation Notes

Installation is performed by licensed plumbers, HVAC technicians, or qualified industrial mechanics. Shut off all fluid flow and relieve system pressure before removing the old O-ring. Inspect the mating groove for damage or debris before seating the new ring. Avoid stretching or twisting the O-ring during installation to preserve the integrity of the encapsulation layer.
