Value Collection ZMSCV70176 Viton O-ring Dash 176

Product Description

The VALUE COLLECTION ZMSCV70176 is a Dash 176 Viton fluoroelastomer O-ring designed for static and dynamic sealing applications across HVAC, plumbing, and industrial fluid systems. Measuring 9.25 inches inside diameter with a 9.438 inch outside diameter and a 3/32 inch (0.0937 inch) thick round cross section, this O-ring is molded to a Shore A hardness of 70. Fluoroelastomer construction delivers strong resistance to petroleum-based fluids, high operating temperatures up to 400 degrees F, and low gas permeability, making it a dependable choice when standard nitrile or EPDM compounds fall short.

This O-ring is suited for use in fuel and oil handling systems, hydraulic assemblies, refrigeration and HVAC equipment, and industrial machinery where exposure to petroleum products or elevated temperatures is a factor. Its wide chemical compatibility and low compression set make it appropriate for both new installations and service replacements in residential and light commercial applications. Typical installers include HVAC technicians, plumbers, and industrial maintenance mechanics working on valve bodies, pump housings, and fluid-circuit fittings.

Key Features

• Fluoroelastomer (Viton-type) material rated from -15 degrees F to 400 degrees F continuous service
• Shore A hardness of 70 resists extrusion under pressure while maintaining a reliable seal
• Round cross section with low compression set for long-term sealing integrity
• Good resistance to petroleum products, fuels, and a wide spectrum of chemical media
• Suitable for vacuum service and low gas permeability applications
• Black color, Dash 176 per standard O-ring sizing

Compatibility

Designed as a standard Dash 176 O-ring replacement compatible with petroleum products and systems requiring chemical-resistant fluoroelastomer seals. Verify groove dimensions and system media compatibility before installation.

Installation Notes

Installation should be performed by a qualified technician familiar with fluid sealing systems. Always depressurize and isolate the line or component before removing the existing O-ring. Lightly lubricate the O-ring with a compatible grease prior to seating to prevent tearing or rolling during assembly. Do not use petroleum-based lubricants unless confirmed compatible with fluoroelastomer compound.
