Value Collection ZMSCTST124 Ptfe O-ring Dash 124 25-pack

Product Description

The VALUE COLLECTION ZMSCTST124 is a Dash 124 O-ring made from polytetrafluoroethylene (PTFE) for use in high-temperature and chemically aggressive sealing applications. It measures 1.27 inches inside diameter, 1.442 inches outside diameter, and 0.047 inches thick with a rectangular cross section. The PTFE compound delivers a wide service temperature range of -65 to 500 degrees F, making it suitable for steam, chemical, and high-heat fluid systems where standard elastomeric O-rings would degrade. Licensed plumbers, pipefitters, and industrial maintenance technicians typically work with this seal type during valve, fitting, and manifold service.

This O-ring is sized to the standard Dash 124 designation and is appropriate for static and low-dynamic sealing points in plumbing, HVAC, chemical processing, and general industrial fluid systems. The PTFE material resists a broad range of solvents, acids, and fuels, extending its usefulness across trade applications where seal compatibility with aggressive media is required. Each package contains 25 O-rings, supporting bench-stock replenishment for service shops and field technicians.

Key Features

• PTFE construction provides broad chemical resistance and wide temperature tolerance from -65 to 500 degrees F
• Dash 124 standard sizing ensures drop-in dimensional fit with compatible grooves
• Rectangular cross section for consistent seating in static groove applications
• Medium hardness rating (Durometer 55) balances compression and sealing load
• Sold in a 25-piece package to support shop restocking and bulk service work

Compatibility

Designed as a standard Dash 124 O-ring replacement for static sealing grooves in plumbing, HVAC, and industrial fluid system components requiring PTFE material compatibility.

Installation Notes

Installation should be performed by a qualified plumber, pipefitter, or maintenance technician. Depressurize and drain the system before removing the existing seal. Inspect the groove for nicks, burrs, or corrosion that could damage the new O-ring before seating. Avoid using sharp tools against the sealing surface during installation to prevent cuts that cause premature seal failure.
