Value Collection ZMSCV70320 Viton O-ring Dash 320

Product Description

The VALUE COLLECTION ZMSCV70320 is a Dash 320 Viton fluoroelastomer O-ring used to create reliable static or dynamic seals in fluid and gas handling systems. It measures 1.125 inches inside diameter, 1.5 inches outside diameter, and 0.1875 inches thick, with a round cross-section profile and 70 Shore A hardness. The fluoroelastomer compound delivers high-temperature resistance up to 400 degrees F and remains flexible down to -15 degrees F. HVAC technicians, plumbers, and industrial service professionals install this seal in valves, fittings, pumps, and manifold connections where petroleum-based media or elevated temperatures are present.

This O-ring is suited for residential and commercial applications involving petroleum products, hydraulic fluids, and a wide range of chemical media. Its low gas permeability makes it a reliable choice for vacuum service. Typical install scenarios include refrigeration service valves, fuel-handling components, and high-temperature plumbing connections where standard nitrile or EPDM compounds are not rated for the service conditions.

Key Features

• Fluoroelastomer (Viton) compound rated for service up to 400 degrees F
• Low minimum working temperature of -15 degrees F for cold-environment applications
• 70 Shore A hardness rated as hard for reduced compression set over time
• Round cross-section for consistent seating in standard O-ring grooves
• Good resistance to petroleum products and broad chemical compatibility
• Low gas permeability suitable for vacuum service applications

Compatibility

Designed as an OEM-style replacement or service seal for Dash 320 O-ring groove applications in valves, fittings, pumps, and mechanical assemblies where fluoroelastomer material is specified. Compatible with petroleum-based media per supplier data.

Installation Notes

Installation should be performed by a qualified technician. Depressurize, de-energize, and isolate the system before removing the old seal. Inspect the O-ring groove for burrs or damage before seating the new ring. Avoid twisting the O-ring during installation, and use only lubricants compatible with fluoroelastomer compounds.
