Value Collection ZMSCTFE218 Ptfe O-ring Dash 218 50-pack

Product Description

The VALUE COLLECTION ZMSCTFE218 is a Dash 218 PTFE (polytetrafluoroethylene) O-ring packaged in quantities of 50. It features a 1.25-inch inside diameter, 1.5-inch outside diameter, and a 0.125-inch cross-section thickness with a round cross-section profile. PTFE construction delivers chemical inertness, low friction, and a working temperature range of -300 degrees F to 500 degrees F, making it well-suited for demanding fluid and gas sealing applications in plumbing, HVAC, chemical process, and industrial systems. Hardness is rated at 55 (medium). Licensed tradespeople and maintenance technicians working with aggressive media or wide temperature swings will find the material properties here particularly relevant.

This O-ring is used wherever a chemically resistant, thermally stable seal is required. Common install scenarios include pump seals, valve stems, manifold connections, and pipe fittings exposed to solvents, refrigerants, acids, or high-temperature steam. The Dash 218 size designation is a standard cross-reference used across multiple industries to simplify replacement sourcing. Each package contains 50 rings, supporting both single-job service calls and stock replenishment for shop inventory.

Key Features

• PTFE material provides chemical inertness and zero water absorption for use with aggressive media
• Operating range of -300 degrees F to 500 degrees F handles extreme thermal cycling
• Round cross-section, Dash 218 designation for straightforward cross-reference and replacement
• Medium hardness (55) balances flexibility and compression resistance in static and dynamic sealing
• Low friction surface reduces wear in applications with relative motion between sealing surfaces
• 50-piece packaging supports service-truck stock and bulk job requirements

Compatibility

Designed as a standard Dash 218 O-ring replacement for valves, pumps, fittings, and fluid-handling components requiring a 1.25-inch ID by 1.5-inch OD by 0.125-inch thick seal in PTFE material.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or qualified maintenance professional. Shut off all fluid or gas supply and relieve system pressure completely before removing any sealing components. Ensure the groove and mating surface are clean and free of debris before seating the O-ring. Do not stretch or nick the ring during installation, as PTFE has lower elasticity than rubber-based compounds and is more susceptible to mechanical damage during handling.
