Value Collection ZMSCTST014 Ptfe O-ring Dash 014

Product Description

The VALUE COLLECTION ZMSCTST014 is a Dash 014 O-ring manufactured from polytetrafluoroethylene (PTFE), a high-performance fluoropolymer known for its broad chemical resistance and wide temperature range. This O-ring measures 0.518 inches inside diameter, 0.624 inches outside diameter, and 0.048 inches thick with a rectangular cross section. It carries a medium hardness rating of 55 durometer and is rated for service from -65 degrees F to 500 degrees F. HVAC technicians, plumbers, and industrial mechanics use PTFE O-rings in applications where standard nitrile or EPDM compounds fail due to chemical exposure or extreme temperature.

This O-ring is suited for use in fluid and gas sealing applications that demand chemical inertness and thermal stability. Common install scenarios include refrigerant-side fittings, chemical pump assemblies, hydraulic connectors, and high-temperature plumbing joints. The Dash 014 designation follows standard AS568 sizing, making it a straightforward dimensional match for any application calling out Dash 014 geometry. Sold in packages of 50 units, it is practical for service shops and maintenance operations that replace O-rings in volume.

Key Features

• PTFE construction provides excellent resistance to a wide range of chemicals and refrigerants
• Rated from -65 degrees F to 500 degrees F for high- and low-temperature service
• Rectangular cross section for consistent seating in standard Dash 014 grooves
• 55 durometer medium hardness balances compressibility and extrusion resistance
• AS568 Dash 014 standard sizing for predictable fitment across OEM and aftermarket hardware
• Packaged in quantities of 50 for shop and fleet maintenance use

Compatibility

Designed as a standard Dash 014 O-ring replacement for any application requiring an AS568-dimensioned seal in PTFE material, including fluid handling, refrigeration, and high-temperature plumbing assemblies.

Installation Notes

Installation should be performed by a qualified technician familiar with sealing system service. Depressurize and isolate the system before removing the existing O-ring. Inspect the mating groove for damage, debris, or corrosion before seating the new ring. PTFE O-rings are generally installed dry and do not require lubrication, but confirm with the equipment manufacturer's service documentation before applying any lubricant or sealant compound.
