Value Collection ZMSCTFE228 Ptfe O-ring Dash 228

Product Description

The VALUE COLLECTION ZMSCTFE228 is a PTFE (polytetrafluoroethylene) O-ring with a round cross section, designed for sealing applications that demand chemical resistance and wide temperature tolerance. It measures 2.25 inches inside diameter, 2.5 inches outside diameter, and 0.125 inches thick, conforming to Dash 228 sizing. PTFE construction provides chemical inertness, low friction, and a rated working range of -300 degrees F to 500 degrees F. Licensed plumbers, HVAC technicians, and industrial service professionals install this type of seal in high-purity, high-temperature, or chemically aggressive fluid systems where elastomeric O-rings would degrade.

This O-ring is suited for use in residential and commercial plumbing, HVAC refrigerant circuits, chemical process lines, and fluid handling equipment where PTFE's unique combination of heat resistance, weatherability, zero water absorption, and dielectric strength is required. Its medium hardness rating makes it appropriate for static face-seal and fitting applications. Each package contains 10 O-rings, and the minimum order quantity is 1 package.

Key Features

• PTFE material offers broad chemical inertness for aggressive fluid compatibility
• Operating range of -300 degrees F to 500 degrees F suits extreme-temperature service
• Dash 228 standard sizing for straightforward cross-referencing and replacement
• Round cross section and medium hardness (55) for reliable static sealing
• Low friction and zero water absorption reduce seal degradation over time
• Sold in packs of 10 for stocking efficiency on multi-unit service calls

Compatibility

Designed as a standard Dash 228 PTFE O-ring replacement suitable for static sealing applications in plumbing, HVAC, and chemical fluid systems that require PTFE material compatibility.

Installation Notes

Installation should be performed by a qualified plumber, HVAC technician, or industrial mechanic familiar with O-ring face-seal and fitting applications. Depressurize and isolate the system before disassembling any fitting or valve housing. Inspect the seating surface for nicks or corrosion before installing the new O-ring, as surface defects will cause seal failure. PTFE O-rings should not be stretched excessively during installation; confirm correct dash sizing before proceeding.
