The VALUE COLLECTION ZMSCV70363 is a Dash 363 Viton (fluoroelastomer) O-ring with a round cross section, sized at 6.5 inches inside diameter, 6.875 inches outside diameter, and 0.1875 inches thick. Rated at 70 durometer (hard), it operates across a temperature range of -15 degrees F to 400 degrees F. The fluoroelastomer compound delivers low compression set, good resistance to petroleum products, high temperature resistance, and low gas permeability, making it well suited for demanding sealing applications in HVAC, plumbing, and industrial fluid systems. Licensed tradespeople and maintenance technicians install this O-ring where a reliable static or dynamic face seal is required.
This O-ring is used in residential and commercial applications wherever a Dash 363 size seal is specified. Typical installations include pump housings, valve bodies, manifolds, and fluid line connections that handle petroleum-based fluids or operate at elevated temperatures. Its wide spectrum of chemical compatibility and suitability for vacuum service extend its use beyond standard water or refrigerant circuits. It ships in a package quantity of two, which accommodates common replace-in-pairs service practices.
Designed as an OEM-style replacement or service O-ring for any application requiring a Dash 363 size fluoroelastomer seal with a round cross section and 70 durometer hardness.
Installation is typically performed by licensed plumbers, HVAC technicians, or mechanical maintenance professionals. Always shut off fluid flow and relieve system pressure before replacing an O-ring. Clean the seating groove thoroughly and inspect it for damage or corrosion before installing the new seal. Avoid twisting or stretching the O-ring during installation, and use only a lubricant compatible with fluoroelastomer materials and the system fluid.
