Value Collection ZMSCTST228 Ptfe O-ring Dash 228

Product Description

The VALUE COLLECTION ZMSCTST228 is a polytetrafluoroethylene (PTFE) O-ring with a rectangular cross section, designed for static and dynamic sealing applications across a broad range of industrial and mechanical systems. It measures 2.272 inches inside diameter, 2.510 inches outside diameter, and 0.047 inches thick. The PTFE compound delivers a working temperature range of -65 to 500 degrees F, making it suitable for high-temperature fluid and gas sealing duties where standard elastomers would degrade. Plumbers, HVAC technicians, and industrial maintenance professionals commonly install this type of seal during equipment assembly or preventive maintenance service.

This O-ring suits applications in fluid handling systems, valves, pumps, and piping connections where chemical resistance and thermal stability are priorities. The Dash 228 designation follows standard O-ring sizing conventions, allowing straightforward cross-referencing when replacing a worn or damaged seal in an existing assembly. It is sold in packages of 10, making it practical for shops and service fleets that install multiple units per job.

Key Features

• PTFE material provides broad chemical resistance and high-temperature stability
• Operating range of -65 to 500 degrees F suits demanding thermal environments
• Rectangular cross section with medium hardness rating (Durometer 55) for consistent seating
• Standard Dash 228 sizing for easy cross-referencing and replacement
• Sold in packs of 10 to support multi-unit service work

Compatibility

Designed as a standard Dash 228 O-ring replacement for valves, pumps, fittings, and fluid handling components that specify a PTFE rectangular-section seal at this diameter.

Installation Notes

Installation should be performed by a qualified technician. Depressurize and isolate the system before removing the old seal. Inspect the groove for scoring or contamination before seating the new O-ring. PTFE seals should be installed without lubrication in most applications unless the equipment manufacturer specifies otherwise.
