Value Collection ZMSCV70177 Viton O-ring Dash 177

Product Description

The VALUE COLLECTION ZMSCV70177 is a Dash 177 Viton (fluoroelastomer) O-ring designed for static and dynamic sealing applications where high-temperature resistance and chemical compatibility are required. With a 9.5-inch inside diameter, 9.688-inch outside diameter, and 3/32-inch (0.0937-inch) cross-section thickness, this round cross-section ring seats reliably in standard Dash 177 grooves. The 70 durometer hardness rating places it in the hard range, minimizing compression set under sustained load. Operating range spans -15 degrees F to 400 degrees F, making it suitable for demanding thermal environments encountered in HVAC, plumbing, and industrial fluid systems.

This O-ring is suited for sealing petroleum-based fluids, hydraulic media, and refrigerant-adjacent applications where fluoroelastomer's broad chemical resistance is an advantage. It is commonly installed in pump housings, valve bodies, manifolds, and pipe flanges in both commercial and industrial settings. The Dash 177 designation follows standard AS568 sizing, allowing direct substitution wherever a Dash 177 groove is specified. Each package contains 2 rings. Licensed tradespeople and maintenance technicians working on fluid-handling equipment are the primary installers.

Key Features

• Fluoroelastomer (Viton) compound provides wide-spectrum chemical compatibility including petroleum products
• Operating temperature range of -15 degrees F to 400 degrees F suits high-heat service environments
• 70 durometer hardness delivers low compression set for long-term sealing integrity
• Round cross-section profile fits standard Dash 177 AS568 grooves
• Good for vacuum service with low gas permeability
• Package quantity of 2 rings per order

Compatibility

Designed as a standard Dash 177 O-ring replacement compatible with petroleum products and a wide spectrum of chemical media; suitable for any application calling for an AS568 Dash 177 fluoroelastomer seal with a 9.5-inch inside diameter and 3/32-inch cross-section.

Installation Notes

Isolate and depressurize the system and shut off all fluid supply before removing the old seal. Inspect the groove for nicks, corrosion, or debris that could compromise the new O-ring seat. Lubricate the ring with a compatible fluid or grease before installation to prevent twisting or tearing during assembly. Follow applicable industry codes and the equipment manufacturer's torque specifications when reassembling flanges or caps.
