Value Collection ZMSCV70042 Viton O-ring Dash 042 10-pack

Product Description

The VALUE COLLECTION ZMSCV70042 is a Dash 042 Viton (fluoroelastomer) O-ring used to create static or dynamic seals in fluid and gas handling systems. With a 3.25-inch inside diameter, 3.375-inch outside diameter, and a 0.0625-inch round cross section, this O-ring seats in standard Dash 042 grooves. The fluoroelastomer compound delivers high temperature resistance up to 400 degrees F, low compression set, and broad chemical compatibility. It is sold in packs of 10 and is suited for use by HVAC technicians, plumbers, and industrial maintenance professionals working on pumps, valves, fittings, and refrigeration components.

This O-ring is appropriate for residential and commercial applications where exposure to petroleum products, fuels, oils, or elevated temperatures is a concern. The round cross section fits standard Dash 042 gland dimensions. Typical install scenarios include pump shaft seals, valve bonnets, pipe unions, and refrigerant service ports. The low gas permeability characteristic also makes it suitable for vacuum service applications.

Installation Notes

Installation of O-rings in pressurized fluid or gas systems should be performed by a qualified plumber, HVAC technician, or industrial mechanic. Depressurize and drain the system fully before replacing any seal. Lubricate the O-ring with a compatible lubricant prior to seating to prevent tearing during assembly. Inspect the groove for nicks or burrs that could compromise the seal before installing the new O-ring.
