Value Collection ZMSCV70264 Viton O-ring Dash 264

Product Description

The VALUE COLLECTION ZMSCV70264 is a Dash 264 Viton (fluoroelastomer) O-ring with a round cross section, designed for static and dynamic sealing applications in systems that handle petroleum products, high-temperature fluids, and aggressive chemicals. It measures 7.5 inches inside diameter, 7.75 inches outside diameter, and 0.125 inches thick. With a hardness rating of 70 Shore A, this O-ring maintains a low compression set under sustained load. The fluoroelastomer compound delivers high temperature resistance up to 400 degrees F, making it suitable for demanding industrial and mechanical sealing environments. Licensed plumbers, pipefitters, and maintenance technicians are the typical installers.

This O-ring is suited for use in sealing flanges, valve bodies, pump housings, and pipe connections where exposure to petroleum-based fluids, fuels, or elevated temperatures is expected. Its low gas permeability makes it appropriate for vacuum service applications as well. The wide chemical compatibility of fluoroelastomer compounds extends its use into HVAC, plumbing, and industrial process piping where standard nitrile or EPDM seals fall short. The part is sold in a package quantity of two.

Compatibility

Designed as a standard Dash 264 O-ring replacement for grooves and glands sized to a 7.5-inch inside diameter, 7.75-inch outside diameter, and 0.125-inch cross-section thickness. Compatible with petroleum products per manufacturer specification.

Installation Notes

Installation is typically performed by licensed plumbers, pipefitters, or mechanical technicians. Shut down and depressurize the system fully before removing the existing seal. Clean the gland groove and mating surfaces of debris or residual seal material before seating the new O-ring. Avoid twisting or over-stretching the O-ring during installation, as distortion reduces sealing performance and service life.
