Value Collection ZMSCVB75028 Viton O-ring Dash 028 50-pack

Product Description

The VALUE COLLECTION ZMSCVB75028 is a Dash 028 Viton (fluoroelastomer) O-ring sold in a package of 50. It measures 1.375 inches inside diameter, 1.5 inches outside diameter, and 0.0625 inches thick with a round cross-section. The compound carries a Shore A hardness of 75, placing it in the hard hardness rating category. Rated for service from -15 degrees F to 400 degrees F, this O-ring suits high-temperature fluid and gas sealing applications where petroleum-based media, wide-spectrum chemical exposure, or vacuum service is a concern. Fluoroelastomer construction provides low compression set and low gas permeability.

This O-ring is used in HVAC, plumbing, hydraulic, pneumatic, and industrial equipment where a reliable static or dynamic face seal or radial seal is required. The Dash 028 sizing is a standard AS568 designation, making it a direct fit in any groove machined to that standard. Its resistance to petroleum products and high-temperature stability make it well suited for fuel systems, refrigerant service valves, pump seals, and process fittings across residential and light commercial applications. The 50-piece pack supports shop stock or service van inventory.

Installation Notes

Installation is typically performed by licensed HVAC technicians, plumbers, or industrial mechanics depending on the application. Always depressurize and de-energize the system before replacing any O-ring seal. Inspect the mating groove for nicks, burrs, or corrosion before installing the new ring. Use only lubricants compatible with fluoroelastomer compounds; avoid silicone greases where petroleum-based media is present, and do not twist or roll the O-ring during installation.
