Value Collection TES70124 O-ring Dash 124 Ptfe Silicone

Product Description

The VALUE COLLECTION TES70124 is a Dash 124 O-ring constructed with polytetrafluoroethylene-encapsulated silicone, commonly referred to as PTFE FEP encapsulated. It measures 1.25 inches inside diameter, 1.438 inches outside diameter, and 0.0937 inches thick with a round cross section. The seamless FEP encapsulation fully encloses a silicone elastomer core, delivering the chemical and temperature resistance of solid PTFE combined with the elasticity and recovery of silicone. This O-ring is suited for plumbing, fluid handling, and process piping applications where standard elastomer O-rings would degrade. Installation is typically performed by licensed plumbers or mechanical contractors.

This O-ring is designed for use in fluid system connections, valve stems, pump seals, and fittings where exposure to aggressive chemicals or wide temperature swings is expected. The PTFE FEP encapsulation makes it appropriate for installations that demand chemical inertness without sacrificing sealing performance. It is rated for a temperature range of -75 degrees F to 400 degrees F, making it usable across refrigeration, hot water, and process fluid systems. The 70 durometer hardness rating provides a firm but compressible seal under standard flange and fitting loads.

Key Features

• Seamless, uniform PTFE FEP encapsulation fully encloses the silicone elastomer core with no gaps or seams
• Chemical resistance matches solid PTFE O-rings while retaining elastomeric recovery
• Operating range of -75 degrees F to 400 degrees F suits a wide range of fluid system applications
• Round cross section in standard Dash 124 sizing for drop-in compatibility with matching grooves
• 70 durometer hardness rating — classified as hard — for reliable compression sealing under load
• Sold individually; minimum order quantity of 1

Compatibility

Designed as a standard Dash 124 replacement O-ring for valves, fittings, pumps, and fluid system components that require a PTFE FEP-encapsulated seal in a 1.25-inch ID groove.

Installation Notes

Installation should be performed by a licensed plumber or qualified mechanical technician. Depressurize and isolate the fluid system completely before removing the old O-ring or installing a replacement. Inspect the mating groove for nicks, corrosion, or debris that could compromise the seal. Avoid using sharp tools or excessive force during installation, as the FEP encapsulation layer can be damaged by cuts or over-stretching.
