Value Collection ZMSCV70044 Viton O-ring Dash 044 10pk

Product Description

The VALUE COLLECTION ZMSCV70044 is a Dash 044 Viton (fluoroelastomer) O-ring with a round cross section, designed for static and dynamic sealing applications across HVAC, plumbing, and industrial service work. It measures 3.75 inches inside diameter, 3.875 inches outside diameter, and 0.0625 inches thick. Rated for continuous service from -15 degrees F to 400 degrees F, this O-ring handles high-temperature environments where standard nitrile or EPDM seals fall short. The fluoroelastomer compound delivers low compression set and low gas permeability, making it well suited for both pressure and vacuum service. Each order contains 10 O-rings.

This O-ring is used wherever petroleum-based fluids, fuels, hydraulic oils, or high-temperature media contact the seal. Common install scenarios include refrigerant service valve seats, fuel system fittings, pump housings, and fluid-line connections in commercial HVAC and industrial plumbing systems. The Dash 044 designation follows AS568 standard sizing, making cross-referencing straightforward for any tech working from a published O-ring kit chart. The black color and 70 Shore A hardness rating indicate a firm, dimensionally stable seal under compression load.

Compatibility

Compatible with petroleum products and systems requiring a high-temperature fluoroelastomer seal. Designed as a standard AS568 Dash 044 replacement O-ring for use in HVAC, plumbing, and industrial fluid-handling applications wherever a 3.75-inch ID seal is specified.

Installation Notes

Installation is typically performed by licensed HVAC technicians, plumbers, or industrial mechanics. Depressurize and lock out the system before removing the old seal. Lightly lubricate the O-ring with a fluid compatible with the system media before seating it in the groove. Avoid rolling or twisting the O-ring during installation, as this can cause premature leakage or seal failure.
