Value Collection ZMSCV70365 Viton O-ring Dash 365

Product Description

The VALUE COLLECTION ZMSCV70365 is a Dash 365 Viton fluoroelastomer O-ring designed for static and dynamic sealing applications across industrial, HVAC, plumbing, and fluid-handling systems. It measures 7 inches inside diameter, 7.375 inches outside diameter, and 0.1875 inches thick, with a round cross section and a Shore A hardness of 70. The fluoroelastomer construction provides high-temperature resistance up to 400 degrees F, a low compression set, and broad chemical compatibility including strong resistance to petroleum-based fluids. Sold in a package quantity of two per order.

This O-ring is suited for use in flanged pipe joints, pump housings, valve bonnets, and similar assemblies where petroleum products, high heat, or vacuum conditions are present. Typical applications include industrial fluid systems, HVAC refrigeration circuits, and hydraulic or pneumatic equipment requiring a reliable elastomeric seal at elevated temperatures. The -15 degrees F minimum working temperature makes it appropriate for a wide range of service environments outside of extreme cold-weather scenarios.

Key Features

• Fluoroelastomer (Viton) material offers strong resistance to petroleum products and wide chemical compatibility
• Operating temperature range of -15 degrees F to 400 degrees F
• Shore A hardness of 70 for consistent compression and sealing force
• Round cross section with low compression set for reliable long-term sealing
• Suitable for vacuum service and exhibits low gas permeability
• Package includes 2 O-rings per order

Compatibility

Designed as an OEM-style replacement or service seal for flanged assemblies, pump housings, valves, and fluid-system components requiring a Dash 365 O-ring in fluoroelastomer material. Compatible with petroleum-based fluids and systems operating within the stated temperature range.

Installation Notes

Installation is typically performed by licensed plumbers, pipefitters, HVAC technicians, or industrial maintenance technicians. Always depressurize and de-energize the system before replacing seals, and drain any residual fluid from the assembly. Inspect the mating groove for burrs or contamination before seating the O-ring. A compatible O-ring lubricant approved for use with fluoroelastomer compounds may be applied to ease installation and prevent damage during assembly.
