Value Collection ZMSCV70137 Viton O-ring Dash 137

Product Description

The VALUE COLLECTION ZMSCV70137 is a Dash 137 Viton (fluoroelastomer) O-ring designed for static and dynamic sealing applications in systems where petroleum-based fluids, elevated temperatures, and wide-spectrum chemical exposure are concerns. It measures 2.0625 inches inside diameter, 2.25 inches outside diameter, and 0.0937 inches thick, with a round cross section and a Shore A hardness rating of 70. This O-ring is suited for use in HVAC, plumbing, hydraulic, and fuel-system applications where standard nitrile seals fall short. Licensed technicians and journeyman mechanics handling petroleum-compatible assemblies are the primary installers.

This O-ring fits Dash 137 groove specifications and is appropriate for use in residential and commercial service environments involving petroleum-product exposure. It performs across a working temperature range of -15 degrees F to 400 degrees F, making it viable for high-temperature plumbing, refrigeration service valves, fuel shut-off assemblies, and vacuum service applications. Each package contains 10 O-rings, sold in multiples of 1 package.

Key Features

• Fluoroelastomer (Viton) construction offers good resistance to petroleum products and fuels
• Low compression set maintains seal integrity over extended service cycles
• High-temperature resistance rated to 400 degrees F continuous working temperature
• Good for vacuum service with low gas permeability
• Wide-spectrum chemical compatibility for use in diverse fluid systems
• Round cross section conforms to standard Dash 137 O-ring groove dimensions

Compatibility

Designed as a Dash 137 standard O-ring replacement compatible with petroleum products and assemblies requiring fluoroelastomer sealing material; verify groove dimensions against 2.0625 inches ID, 2.25 inches OD, and 0.0937 inches cross-section thickness before installation.

Installation Notes

Install by a qualified HVAC technician, plumber, or mechanic following applicable system codes. De-energize electrical components and shut off all fluid supply and pressure before disassembling any fitting or valve. Lubricate the O-ring with a compatible fluid prior to seating to prevent tearing during installation. Do not roll or twist the O-ring into the groove — seat it evenly by hand to ensure uniform compression.
