Value Collection ZMSCTFE125 Ptfe O-ring Dash 125 Pack 25

Product Description

The VALUE COLLECTION ZMSCTFE125 is a Dash 125 PTFE (polytetrafluoroethylene) O-ring designed for static and dynamic sealing applications where chemical resistance and wide temperature range are critical. With a 1.313-inch inside diameter, 1.500-inch outside diameter, and 0.094-inch cross-section thickness, this round-section O-ring is manufactured from white thermoplastic fluoroethylene resin. The material delivers chemical inertness, low friction, zero water absorption, and strong dielectric strength. It is suited for use by licensed plumbers, HVAC technicians, and industrial maintenance professionals working with aggressive media or extreme temperature environments.

PTFE O-rings are commonly specified in fluid handling systems, chemical process lines, high-temperature pneumatic assemblies, and potable water or gas fittings where elastomeric materials degrade or swell. This Dash 125 size is a standard AS568 dimension, making it a straightforward replacement in grooves already cut to that specification. The ZMSCTFE125 is packaged in a quantity of 25 per order, suitable for both single-repair use and small-batch stocking. It is appropriate for residential and light commercial applications where broad chemical compatibility is required.

Key Features

• PTFE material provides chemical inertness against a wide range of acids, bases, and solvents
• Operating temperature range of -300 degrees F to 500 degrees F
• Round cross-section, Dash 125 per AS568 standard dimensions
• Zero water absorption — no swelling or dimensional change from moisture exposure
• Medium hardness (Shore 55) balances flexibility and compression set resistance
• Packaged 25 pieces per unit, minimum order quantity of 1 package

Compatibility

Designed as a standard Dash 125 replacement O-ring for any groove or fitting machined to AS568 Dash 125 dimensions, with an inside diameter of 1.313 inches and outside diameter of 1.500 inches.

Installation Notes

PTFE O-rings are installed by licensed plumbers, HVAC technicians, or industrial mechanics working on fluid or gas sealing systems. Always depressurize and isolate the system before removing the old O-ring and inspect the groove for damage or debris prior to installation. Avoid using petroleum-based lubricants on PTFE seals; consult the system manufacturer for an approved assembly lubricant. Verify groove dimensions match Dash 125 specifications before installation to ensure proper compression and sealing.
