Value Collection ZMSCV70274 Viton O-ring Dash 274 2-pack

Product Description

The VALUE COLLECTION ZMSCV70274 is a Dash 274 Viton (fluoroelastomer) O-ring with a 10-inch inside diameter, a 10.25-inch outside diameter, and a cross-section thickness of 0.125 inches. Manufactured from fluoroelastomer compound at a Shore A hardness of 70, this O-ring is suited for static and dynamic sealing applications where exposure to petroleum-based fluids, elevated temperatures, and wide-spectrum chemical environments is a concern. The round cross-section geometry provides consistent compression seating across flanged, grooved, and ported interfaces. Each package contains two O-rings. This part is installed by licensed plumbers, HVAC technicians, pipefitters, and maintenance mechanics working on industrial or commercial sealing applications.

This O-ring is appropriate for sealing applications involving petroleum products, hydraulic fluids, and many industrial chemicals. It is rated for service temperatures from -15 degrees F to 400 degrees F, making it suitable for both chilled and high-temperature process piping, pump housings, valve bodies, and equipment covers where standard Buna-N (nitrile) compounds would degrade. The fluoroelastomer construction also supports vacuum service and offers low gas permeability, which is beneficial in HVAC refrigerant-adjacent assemblies and vacuum-process equipment.

Key Features

• Fluoroelastomer (Viton-type) compound with 70 Shore A hardness for firm, low-compression-set sealing
• Operating temperature range of -15 degrees F to 400 degrees F
• Good resistance to petroleum products, hydraulic fluids, and a wide spectrum of industrial chemicals
• Low gas permeability and suitable for vacuum service applications
• Round cross-section profile for consistent groove seating and uniform compression
• Packaged in quantities of two per order unit

Compatibility

Designed as an OEM-style replacement or maintenance-supply O-ring for industrial, commercial, and HVAC sealing applications requiring a Dash 274 cross-section size in fluoroelastomer material. Compatible with systems and assemblies that contact petroleum products. Not FDA approved; not intended for food, beverage, or pharmaceutical contact service.

Installation Notes

Installation is typically performed by licensed plumbers, pipefitters, or HVAC mechanics. Depressurize and isolate the system before removing the old O-ring; for hydraulic or chemical systems, follow applicable lockout/tagout procedures. Clean the O-ring groove thoroughly and inspect for damage or corrosion before seating the new O-ring. Apply a compatible O-ring lubricant to ease installation and prevent pinching or tearing during assembly.
