Value Collection ZMSCV70237 Viton O-ring Dash 237

Product Description

The VALUE COLLECTION ZMSCV70237 is a Dash 237 Viton fluoroelastomer O-ring designed for static and dynamic sealing applications across HVAC, plumbing, and industrial fluid systems. It measures 3.375 inches inside diameter, 3.625 inches outside diameter, and 0.125 inches thick with a round cross section. The 70 durometer hardness rating provides a firm, reliable seal under mechanical load. Rated for continuous service from -15 degrees F to 400 degrees F, this O-ring is suited for high-temperature environments where standard nitrile or EPDM compounds fall short. It is sold in packages of 10 units.

This O-ring is used in applications requiring resistance to petroleum-based fluids, hydraulic oils, fuels, and a wide range of chemical media. The Viton fluoroelastomer compound delivers low compression set, high temperature resistance, and low gas permeability, making it appropriate for vacuum service as well as pressurized systems. Licensed plumbers, HVAC technicians, and industrial mechanics routinely use Dash 237 O-rings in pump housings, valve bodies, filter housings, and compressor fittings where elevated operating temperatures and petroleum-fluid contact are both present.

Key Features

• Fluoroelastomer (Viton) compound with broad chemical compatibility
• Rated -15 degrees F to 400 degrees F continuous operating range
• 70 durometer hardness for firm sealing under compression
• Low compression set for long-term seal integrity
• Low gas permeability suitable for vacuum service
• Round cross section per standard Dash 237 sizing

Compatibility

Compatible with petroleum products and a wide spectrum of chemical media. Designed as a standard Dash 237 replacement O-ring for use in sealing applications requiring fluoroelastomer resistance to petroleum fluids and elevated temperatures.

Installation Notes

Installation should be performed by a qualified plumber, HVAC technician, or industrial mechanic. Always depressurize and isolate the system before replacing any O-ring. Lubricate the O-ring with a compatible fluid or grease before seating to prevent tearing during assembly. Do not stretch the O-ring over sharp edges or threads, and inspect the gland groove for damage or debris before installation.
