Value Collection ZMSCTFE019 Ptfe O-ring Dash 019 50-pack

Product Description

The VALUE COLLECTION ZMSCTFE019 is a Dash 019 PTFE O-ring sold in a pack of 50, designed for static and dynamic sealing applications where chemical resistance and wide temperature tolerance are required. The ring measures 0.801 inches inside diameter, 0.938 inches outside diameter, and 0.0625 inches thick with a round cross section. Made from polytetrafluoroethylene (PTFE), it operates across a service range of -300 degrees F to 500 degrees F, making it suitable for aggressive fluid environments where standard nitrile or EPDM seals fail. Licensed tradespeople in HVAC, plumbing, and industrial service applications rely on PTFE seals where exposure to refrigerants, acids, solvents, or high-temperature steam is present.

This O-ring is used in residential and commercial service applications requiring a chemically inert seal. Typical installations include valve stems, pump housings, fittings, and manifold connections where the process fluid is incompatible with elastomeric materials. The Dash 019 sizing is a standard AS568 cross-reference dimension, allowing technicians to match it directly to OEM groove specifications without custom measurement. The 50-unit pack supports shop stock replenishment and fleet service operations.

Key Features

• PTFE construction provides chemical inertness against acids, solvents, and refrigerants
• Wide temperature range: -300 degrees F to 500 degrees F
• Round cross section with Dash 019 AS568 standard sizing for direct OEM groove compatibility
• Medium hardness rating (Shore 55) balances sealing compression with flexibility
• Zero water absorption and low friction surface reduce wear in dynamic seal applications
• Pack of 50 units supports bulk stocking for service fleets and shop inventory

Compatibility

Designed as an OEM-style replacement PTFE O-ring for Dash 019 groove applications across valves, fittings, pumps, and manifolds in HVAC, plumbing, and industrial service systems.

Installation Notes

Installation is performed by licensed plumbers, HVAC technicians, or qualified mechanical tradespeople. Always depressurize and isolate the system and confirm fluid compatibility with PTFE before installation. Inspect the mating groove for damage or burrs that could compromise the seal. Do not use petroleum-based lubricants on PTFE O-rings; use a compatible assembly lubricant approved for the process fluid.
