Value Collection ZMSCV70373 Viton O-ring Dash 373

Product Description

The VALUE COLLECTION ZMSCV70373 is a Dash 373 Viton O-ring manufactured from fluoroelastomer (FKM) with a round cross section. It measures 9 inches inside diameter, 9.375 inches outside diameter, and 0.1875 inches thick. Rated at 70 Shore A hardness, this O-ring is suited for static and dynamic sealing applications where resistance to petroleum-based fluids, high temperatures, and wide-spectrum chemical exposure is required. It handles operating temperatures from -15 degrees F to 400 degrees F, making it a practical choice for demanding industrial and mechanical sealing environments. Each package contains 2 O-rings.

This O-ring is appropriate for use in fluid power systems, hydraulic assemblies, plumbing connections, fuel-handling equipment, and vacuum service applications where fluoroelastomer compatibility with petroleum products is needed. Its low gas permeability and low compression set characteristics make it well suited for both sealing and vacuum-hold applications across a range of trade and industrial service scenarios. Installers in HVAC, plumbing, and industrial maintenance will encounter this size in larger-diameter flange and pipe connections.

Key Features

• Fluoroelastomer (Viton) material provides good resistance to petroleum products and a wide spectrum of chemicals
• Operating temperature range of -15 degrees F to 400 degrees F
• 70 Shore A hardness rating for reliable compression sealing
• Low compression set supports long-term seal integrity under sustained load
• Suitable for vacuum service with low gas permeability
• Round cross section, Dash 373 standard sizing

Compatibility

Designed as a standard Dash 373 O-ring replacement compatible with petroleum products and fluoroelastomer-rated sealing applications in hydraulic, plumbing, fuel-handling, and vacuum service assemblies.

Installation Notes

Installation should be performed by a qualified technician familiar with fluid sealing systems. Always depressurize, de-energize, and drain the system before replacing O-rings. Inspect the groove and mating surfaces for damage or contamination prior to installation. Avoid twisting or overstretching the O-ring during seating; use a compatible lubricant rated for fluoroelastomer and the service fluid when inserting into the groove.
