Value Collection ZMSCV70901 Viton O-ring Dash 901 25-pack

Product Description

The VALUE COLLECTION ZMSCV70901 is a Dash 901 Viton (fluoroelastomer) O-ring with a round cross section, designed for sealing applications that demand resistance to high temperatures and petroleum-based fluids. It measures 0.185 inches inside diameter, 0.297 inches outside diameter, and 0.0937 inches thick. With a hardness rating of 70 Shore A, this O-ring maintains a low compression set across a service temperature range of -15 degrees F to 400 degrees F. Each package contains 25 O-rings. Licensed HVAC technicians, plumbers, and equipment mechanics install this type of seal where a durable, chemically resistant elastomer is required in fluid and pneumatic systems.

This O-ring is specified as an O-ring boss gasket for straight-thread tube fittings. It is suited for use in systems carrying petroleum products, hydraulic fluids, and other media compatible with fluoroelastomer compounds. Typical applications include HVAC refrigerant-adjacent fittings, plumbing connections, and industrial equipment where high-temperature and low gas permeability requirements must be met. It is also rated for vacuum service.

Installation Notes

Installation is typically performed by licensed HVAC technicians, plumbers, or qualified mechanics working on fluid or pneumatic systems. Always depressurize and isolate the system before removing or installing O-rings. Inspect the seating surface for nicks or debris that could compromise the seal. Do not reuse a compressed or damaged O-ring; replace with a new part at each service interval.
