Value Collection ZMSCTST216 O-ring Dash 216 Ptfe 50-pack

Product Description

The VALUE COLLECTION ZMSCTST216 is a Dash 216 O-ring made from polytetrafluoroethylene (PTFE), suited for static and dynamic sealing applications where chemical resistance and wide temperature tolerance are required. It measures 1.141 inches inside diameter and 1.379 inches outside diameter, with a cross-section thickness of 0.047 inches. The rectangular cross-section and medium durometer rating of 55 provide reliable compression sealing. Rated for service from -65 degrees F to 500 degrees F, this O-ring performs in demanding fluid and gas systems where standard elastomers fail. HVAC technicians, plumbers, and industrial service professionals routinely use PTFE O-rings in high-heat, chemical-exposure, or corrosive-media environments.

This O-ring is appropriate for use in hydraulic fittings, pneumatic connections, valve stems, pump housings, and refrigerant-circuit components where PTFE's inert properties are needed. The Dash 216 designation identifies its dimensional standard, making cross-referencing straightforward during service and replacement work. Each purchase includes a package quantity of 50 units, making this well-suited for shops and field technicians who need bench stock on hand for recurring seal replacements.

Key Features

• PTFE material provides broad chemical resistance and low friction across a wide range of media
• Operating temperature range of -65 degrees F to 500 degrees F suits extreme-duty applications
• Dash 216 standard sizing ensures straightforward cross-reference and replacement
• Rectangular cross-section for positive compression seating in grooved applications
• Medium hardness rating (Durometer 55) balances sealing force and compressibility
• Package quantity of 50 supports bench stock and fleet service needs

Compatibility

Designed as a Dash 216 standard-dimension replacement O-ring for use in any application specifying a 1.141-inch ID PTFE O-ring of this cross-section thickness.

Installation Notes

O-ring installation should be performed by a qualified technician familiar with the system being serviced. Shut down and depressurize any hydraulic, pneumatic, refrigerant, or fluid system fully before removing existing seals. Inspect the groove and mating surfaces for nicks or corrosion that could compromise the new seal. PTFE O-rings do not require lubrication in most applications, but consult the equipment manufacturer guidelines before applying any sealant or lubricant.
