Value Collection ZMSCV70436 Viton O-ring Dash 436

Product Description

The VALUE COLLECTION ZMSCV70436 is a Dash 436 Viton (fluoroelastomer) O-ring with a round cross section, designed for static and dynamic sealing applications in plumbing, HVAC, and industrial fluid systems. It measures 5.875 inches inside diameter, 6.375 inches outside diameter, and 0.25 inches thick. The fluoroelastomer compound delivers high-temperature resistance up to 400 degrees F and a minimum working temperature of -15 degrees F, making it suitable for demanding service conditions. A Shore hardness rating of 70 provides resistance to compression set while maintaining a reliable seal under pressure and thermal cycling.

This O-ring is suited for applications involving petroleum-based fluids, hydraulic systems, fuel handling equipment, and vacuum service lines. Its wide chemical compatibility and low gas permeability make it a dependable choice for sealing flanges, fittings, valves, and pump housings in both residential and light commercial mechanical systems. Licensed plumbers, HVAC technicians, and maintenance professionals typically install this size in large-bore fittings and equipment service ports. Packaged in a quantity of two per pack.

Compatibility

Designed for use with petroleum products and compatible fluids in applications requiring Dash 436 standard O-ring sizing. Not FDA approved — confirm suitability before use in food-contact or potable-water applications.

Installation Notes

Power down or de-energize any associated equipment and relieve system pressure before replacing an O-ring in a pressurized circuit. Inspect the seating groove for wear, nicks, or contamination before installing the new ring. Lubricate the O-ring with a compatible grease or fluid prior to installation to prevent tearing during assembly. Follow applicable mechanical and plumbing codes for the system type being serviced.
