Value Collection ZMSCTST112 Ptfe O-ring Dash 112

Product Description

The VALUE COLLECTION ZMSCTST112 is a Dash 112 O-ring made from polytetrafluoroethylene (PTFE) for use in static sealing applications where chemical resistance and wide temperature range are required. It measures 0.515 inches inner diameter, 0.688 inches outer diameter, and 0.0468 inches thick with a rectangular cross section. The durometer hardness rating is 55, placing it in the medium hardness range. PTFE construction provides excellent resistance to aggressive chemicals, solvents, and extreme temperatures, making it a reliable choice for plumbing, HVAC, and industrial fluid system maintenance.

This O-ring is suited for static face-seal and groove applications in residential and commercial systems where standard rubber compounds would degrade. Typical installations include valve seats, pipe unions, fittings, and instrumentation connections that see wide thermal cycling or exposure to corrosive media. The Dash 112 designation is a standard AS568 size, widely referenced by plumbing and HVAC technicians when sourcing replacement seals. Sold in a package quantity of 50 units, this SKU is appropriate for service shops and technicians who replace O-rings as part of regular maintenance work.

Key Features

• PTFE material offers broad chemical resistance and a wide service temperature range from -65 degrees F to 500 degrees F

• Dash 112 standard size for straightforward cross-referencing and replacement sourcing
• Medium hardness at durometer 55 provides reliable compression and sealing in typical groove fits
• Sold in a 50-piece package, practical for service stock or multi-unit repair jobs

Compatibility

Designed as a standard Dash 112 AS568-size replacement O-ring for static sealing grooves in plumbing, HVAC, and fluid handling applications requiring PTFE material compatibility.

Installation Notes

Installation should be performed by a qualified plumber, HVAC technician, or pipefitter. Shut off and depressurize the system fully before removing any fittings or valve assemblies. Inspect the groove for wear, scoring, or contamination before seating the new O-ring. Do not stretch or twist the O-ring during installation, and avoid using petroleum-based lubricants with PTFE seals.
