Value Collection TEV80333 O-ring Dash 333 Ptfe Viton

Product Description

The VALUE COLLECTION TEV80333 is a Dash 333 PTFE-encapsulated Viton o-ring used to create reliable fluid and gas seals in demanding service environments. The ring measures 2.5 inches inside diameter, 2.875 inches outside diameter, and 0.1875 inches thick with a round cross section. Construction features a seamless, uniform FEP Teflon encapsulation that completely encloses a Viton elastomer core. This design combines the chemical resistance of solid PTFE with the elasticity and compression recovery of Viton, making it suitable for applications where standard elastomer o-rings would degrade. Licensed plumbers, pipefitters, and industrial maintenance technicians are the primary installers.

This o-ring is suited for static and dynamic sealing in piping, valve, pump, and fitting assemblies where exposure to aggressive chemicals, solvents, or wide temperature swings is a concern. The rated temperature range of -75 degrees F to 400 degrees F covers most commercial and industrial process applications. Its hard durometer rating and seamless encapsulation make it a strong candidate for applications where standard rubber o-rings fail prematurely due to chemical attack or thermal cycling.

Key Features

• Seamless FEP Teflon encapsulation completely encloses a Viton elastomer core for dual-material performance
• Rated from -75 degrees F to 400 degrees F continuous service temperature
• Round cross section at 0.1875 inches thick for consistent seating in standard Dash 333 grooves
• Hard (80 durometer) hardness rating for resistance to extrusion under pressure
• Matches chemical and temperature resistance of solid PTFE while retaining elastomeric recovery
• Round cross section is seamless and uniform for leak-free installation

Compatibility

Designed to fit standard Dash 333 o-ring grooves with a 2.5-inch inside diameter and 0.1875-inch cross-section thickness, consistent with AS568 Dash 333 dimensional standards.

Installation Notes

Shut off and depressurize the system completely before removing or installing any o-ring seal. Clean the groove and mating surfaces of debris, old sealant, and residual elastomer before installing the new ring. Avoid sharp tools that can nick or cut the PTFE encapsulation, as surface damage will compromise the seal. Follow applicable plumbing or piping codes such as IPC or ASME B31 for the system being serviced.
