Value Collection ZMSCV70348 Viton O-ring Dash 348

Product Description

The VALUE COLLECTION ZMSCV70348 is a Dash 348 Viton (fluoroelastomer) O-ring used to create a reliable static or dynamic seal in fluid and gas systems. It measures 4.375 inches inside diameter, 4.75 inches outside diameter, and 0.1875 inches thick with a round cross section. Rated at 70 Shore A hardness, this O-ring is engineered for high-temperature service up to 400 degrees F and handles minimum working temperatures down to -15 degrees F. Its fluoroelastomer compound delivers low compression set and low gas permeability, making it a dependable choice for demanding sealing applications. Each package contains 2 O-rings.

This O-ring is suited for use in HVAC, plumbing, hydraulic, and pneumatic systems where exposure to petroleum products, fuels, or elevated temperatures is common. The Dash 348 designation follows standard AS568 sizing, making it straightforward to source as a drop-in replacement for worn or damaged seals in pumps, valves, compressors, and fittings. It is appropriate for both residential and light commercial service applications where chemical compatibility and temperature resistance are required.

Compatibility

Designed as a standard Dash 348 AS568-sized replacement O-ring compatible with petroleum-based fluids and gases. Suitable for use with pumps, valves, fittings, and compressors requiring a fluoroelastomer seal at this dimensional specification.

Installation Notes

Installation is typically performed by licensed plumbers, HVAC technicians, or hydraulic system technicians. Always depressurize and isolate the system before removing the existing O-ring. Clean the groove thoroughly and inspect for damage before seating the new O-ring. Avoid stretching the O-ring excessively during installation and do not use petroleum-based lubricants that are incompatible with fluoroelastomer compounds.
