Value Collection ZMSCV70174 Viton O-ring Dash 174

Product Description

The VALUE COLLECTION ZMSCV70174 is a Dash 174 Viton (fluoroelastomer) O-ring with a round cross section, designed for static and dynamic sealing applications in demanding industrial and mechanical environments. It measures 8.75 inches inside diameter (ID), 8.938 inches outside diameter (OD), and 0.0937 inches thick. The fluoroelastomer compound delivers high temperature resistance up to 400 degrees F and maintains sealing integrity down to -15 degrees F. Its low compression set and low gas permeability make it a reliable choice for vacuum service, fluid system connections, and petroleum-based fluid containment. Licensed tradespeople and maintenance technicians working in HVAC, plumbing, hydraulic, and industrial fluid systems commonly install this ring.

This O-ring is suited for sealing flanges, valve bodies, pump housings, and pipe connections where exposure to petroleum products, elevated temperatures, or chemical environments is expected. The Dash 174 sizing is a standard AS568 designation, making it a direct fit in grooves machined to that standard. Applications span residential and commercial equipment including fuel systems, hydraulic circuits, and high-temperature water or chemical process lines. It is sold in a package quantity of 2 per order.

Key Features

• Fluoroelastomer (Viton-type) material provides broad chemical compatibility and high heat resistance
• Operating temperature range from -15 degrees F to 400 degrees F
• Low compression set helps maintain a consistent seal under sustained load
• Low gas permeability makes it suitable for vacuum service applications
• Good resistance to petroleum products and petroleum-based fluids
• Round cross section conforms to standard AS568 Dash 174 groove geometry

Compatibility

Designed as a standard AS568 Dash 174 replacement O-ring for any groove or fitting machined to the Dash 174 specification. Compatible with petroleum products and a wide spectrum of chemical media. Not FDA approved.

Installation Notes

Installation is typically performed by licensed plumbers, HVAC technicians, or industrial maintenance mechanics during valve, pump, or flange service. Always de-energize and depressurize the system fully before removing the existing O-ring. Clean the groove and mating surfaces of debris and old sealant before seating the new ring. Avoid rolling or twisting the O-ring during installation to prevent cross-section distortion that can cause premature leakage.
