Value Collection ZMSCV70368 Viton O-ring Dash 368

Product Description

The Value Collection ZMSCV70368 is a Dash 368 Viton fluoroelastomer O-ring designed for static and dynamic sealing applications where exposure to petroleum products, high temperatures, or aggressive chemicals is a concern. The round cross-section profile measures 7.75 inches inside diameter, 8.125 inches outside diameter, and 0.1875 inches thick. With a durometer hardness of 70 and a working temperature range of -15 degrees F to 400 degrees F, this O-ring handles demanding service conditions. Plumbers, HVAC technicians, and industrial maintenance professionals install this part where a reliable face or radial seal is required.

This O-ring is suited for use in hydraulic systems, pneumatic assemblies, pump housings, and fluid-handling equipment that contact petroleum-based media. The fluoroelastomer compound provides low gas permeability, making it appropriate for vacuum service applications. Its large diameter positions it in industrial machinery, large-bore valve assemblies, and equipment flanges rather than compact residential plumbing fittings. Any trade or maintenance professional working with petroleum-fluid systems or high-temperature sealing environments will find this a direct-fit sealing solution.

Key Features

• Fluoroelastomer (Viton) compound delivers strong resistance to petroleum products and fuels
• Working temperature range from -15 degrees F to 400 degrees F suits high-heat applications
• 70 durometer hardness rating provides low compression set over extended service
• Low gas permeability makes it compatible with vacuum service requirements
• Round cross-section profile seats cleanly in standard O-ring grooves for Dash 368 dimensions
• Wide chemical compatibility reduces the need for application-specific compound substitutions

Compatibility

Designed as an OEM-style replacement or aftermarket sealing solution for equipment requiring a Dash 368 O-ring groove specification in fluoroelastomer material. Compatible with systems contacting petroleum products.

Installation Notes

Depressurize and isolate the system completely before removing the existing O-ring. Clean the groove and mating surfaces of any debris or residual sealant before seating the new ring. Avoid twisting or rolling the O-ring during installation, as spiral distortion can cause premature seal failure. Lubricate with a compatible fluid or assembly lubricant rated for fluoroelastomer compounds when required by the application.
