Value Collection ZMSCV70330 Viton O-ring Dash 330

Product Description

The VALUE COLLECTION ZMSCV70330 is a Dash 330 Viton (fluoroelastomer) O-ring engineered for demanding sealing applications across HVAC, plumbing, and industrial fluid systems. It features a 2.125-inch inside diameter, 2.5-inch outside diameter, and a 0.1875-inch thick round cross section. The 70 Shore A hardness rating places it in the hard category, offering low compression set and strong resistance to deformation under load. Rated for continuous service from -15 degrees F to 400 degrees F, this O-ring is suited for high-temperature sealing environments where standard nitrile rings fail. Licensed tradespeople and service technicians install it wherever a Dash 330 profile is specified.

This O-ring is appropriate for use in petroleum-based fluid systems, refrigerant service lines, hydraulic assemblies, and vacuum service applications. Its fluoroelastomer compound delivers wide-spectrum chemical compatibility, making it a reliable choice in both residential and light commercial mechanical systems. Typical applications include pump seals, valve stem packing seats, and compressor service fittings where high temperatures and petroleum-based media are present. The black color and round cross-section profile conform to standard O-ring groove dimensions for Dash 330 specifications.

Compatibility

Designed as a standard Dash 330 O-ring replacement compatible with systems and components using petroleum-based media and requiring fluoroelastomer sealing materials. Confirm groove dimensions match the Dash 330 standard before installation.

Installation Notes

Installation is typically performed by licensed HVAC technicians, plumbers, or mechanical service professionals. Always relieve system pressure and isolate the fluid supply before removing or installing O-rings. Lubricate the O-ring with a compatible fluid or grease prior to seating to prevent tearing during assembly. Do not use petroleum-based lubricants incompatible with the system fluid, and never reuse a compressed or damaged O-ring.
