Value Collection ZMSCV70374 Viton O-ring Dash 374

Product Description

The VALUE COLLECTION ZMSCV70374 is a Dash 374 Viton O-ring made from fluoroelastomer with a round cross section. It measures 9.25 inches inside diameter, 9.625 inches outside diameter, and 0.1875 inches thick. Rated at 70 Shore A hardness, this seal handles a working temperature range of -15 degrees F to 400 degrees F. Its fluoroelastomer compound delivers low compression set, high temperature resistance, and low gas permeability, making it a reliable choice for demanding sealing applications. Licensed plumbers, HVAC technicians, and mechanical maintenance professionals install this type of O-ring in fluid and gas handling systems.

This O-ring is suited for use with petroleum-based fluids and a wide range of chemical media. The fluoroelastomer material performs well in vacuum service applications and environments where resistance to fuel, oil, and hydraulic fluid is required. Typical installations include pump assemblies, valve bodies, manifolds, and pipe flanges in commercial and industrial systems. Its hard durometer rating makes it appropriate for static sealing applications where dimensional stability under load is critical.

Key Features

• Fluoroelastomer (Viton) construction for broad chemical compatibility
• Working temperature range of -15 degrees F to 400 degrees F
• 70 Shore A hardness rating for static sealing applications
• Low compression set reduces the risk of seal failure over time
• Low gas permeability suits vacuum service environments
• Good resistance to petroleum products including fuel, oil, and hydraulic fluids

Compatibility

Designed as an OEM-style replacement or service seal for applications requiring a Dash 374 O-ring in fluoroelastomer compound, compatible with petroleum products and a wide spectrum of chemical media.

Installation Notes

Installation should be performed by a qualified plumber, HVAC technician, or mechanical maintenance professional. Depressurize and drain the system completely before removing the old seal or installing the new O-ring. Inspect the seating groove for damage, burrs, or contamination before fitting the replacement. Use only lubricants compatible with fluoroelastomer to avoid degrading the seal material.
