Value Collection ZMSCV70272 Viton O-ring Dash 272

Product Description

The VALUE COLLECTION ZMSCV70272 is a Dash 272 Viton O-ring manufactured from fluoroelastomer compound and designed for demanding sealing applications in HVAC, plumbing, and industrial systems. With a 9.5-inch inside diameter, 9.75-inch outside diameter, and 0.125-inch cross-section thickness, this round-profile ring delivers a reliable static or dynamic seal where heat resistance and chemical compatibility are priorities. The fluoroelastomer compound supports continuous service from -15 degrees F up to 400 degrees F, making it suitable for high-temperature environments that would degrade standard Buna-N or EPDM seals. A Shore hardness rating of 70 (Hard) provides controlled compression without excessive deformation under load. Sold in a package of two rings.

This O-ring is suited for use in petroleum-fluid systems, refrigeration equipment, hydraulic circuits, and vacuum service assemblies. The Dash 272 designation follows the AS568 standard sizing convention, which allows straightforward cross-referencing when replacing worn or damaged seals in large-bore fittings, manifolds, pump housings, or valve bodies. Plumbers, HVAC technicians, and industrial maintenance professionals install this size in applications where larger-diameter sealing surfaces require a chemically resistant fluoroelastomer compound rather than a general-purpose elastomer.

Key Features

• Fluoroelastomer (Viton-type) material rated for service up to 400 degrees F
• Low compression set characteristics help maintain sealing force over extended service intervals
• Good resistance to petroleum products, hydraulic fluids, and a wide spectrum of chemicals
• Low gas permeability makes this ring suitable for vacuum service applications
• Round cross-section profile conforms to AS568 Dash 272 standard dimensions
• Shore hardness 70 (Hard) for controlled deformation under compression load

Compatibility

Designed as an OEM-style replacement for large-bore fluoroelastomer O-ring applications requiring AS568 Dash 272 dimensions and compatibility with petroleum products and high-temperature service conditions.

Installation Notes

Shut down and depressurize the system completely before removing the old O-ring. Inspect the groove and sealing surfaces for scoring or corrosion before installing the new ring. Apply a thin film of a compatible lubricant — one rated for use with fluoroelastomer compounds and the process fluid — to ease installation and reduce the risk of twisting or cutting the ring during assembly. Fluoroelastomer O-ring service in refrigeration, gas, or plumbing systems must comply with applicable local mechanical codes and manufacturer specifications.
