Value Collection ZMSCV70268 Viton O-ring Dash 268

Product Description

The VALUE COLLECTION ZMSCV70268 is a Dash 268 Viton O-ring with a round cross section, manufactured from fluoroelastomer for reliable sealing in demanding service environments. It measures 8.5 inches inside diameter, 8.75 inches outside diameter, and 0.125 inches thick. With a hardness rating of 70 Shore A and a working temperature range of -15 degrees F to 400 degrees F, this O-ring is engineered for applications involving elevated heat, petroleum-based fluids, and aggressive chemical exposure. Licensed plumbers, HVAC technicians, and industrial maintenance professionals use this seal where standard rubber compounds fall short.

This O-ring is suited for use in plumbing, HVAC, refrigeration, and general industrial fluid-handling systems where resistance to petroleum products and high temperatures is required. Its low compression set and low gas permeability also make it appropriate for vacuum service applications. The fluoroelastomer construction provides a wide spectrum of chemical compatibility, extending service life in systems that cycle through temperature extremes or contact hydrocarbon-based media. Sold in a package quantity of two.

Key Features

Compatibility

Designed as an OEM-style replacement or service seal for applications requiring a Dash 268 O-ring in fluoroelastomer. Compatible with systems and media involving petroleum products where fluoroelastomer compounds are specified.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or qualified industrial mechanic. Depressurize and drain the system completely before removing the existing O-ring or installing a replacement. Inspect the mating groove for nicks, corrosion, or debris that could compromise the seal. Lubricate the O-ring with a compatible grease before installation to prevent tearing and aid seating.
