Value Collection ZMSCVB75236 Viton O-ring Dash 236

Product Description

The VALUE COLLECTION ZMSCVB75236 is a Dash 236 Viton (fluoroelastomer) O-ring designed for static and dynamic sealing applications where high temperatures and chemical exposure are a concern. With a 3.25-inch inside diameter, 3.5-inch outside diameter, and a 0.125-inch cross-section thickness, this round-section ring provides a reliable seal across a wide range of industrial and mechanical systems. The fluoroelastomer compound delivers low compression set and low gas permeability, making it a dependable choice for technicians working on equipment that handles petroleum-based fluids, fuels, and hydraulic media. Sold in packages of 10.

This O-ring is suited for use in hydraulic systems, fuel handling equipment, pumps, valves, and fluid connectors where operating temperatures range from -15 degrees F to 400 degrees F. Its broad chemical compatibility and resistance to petroleum products make it appropriate for HVAC refrigeration circuits, plumbing assemblies, and industrial fluid systems that require a hard (75 durometer) sealing element. The Dash 236 designation follows standard AS568 sizing, allowing straightforward cross-referencing across groove specifications.

Compatibility

Designed as a standard Dash 236 fluoroelastomer O-ring for use in grooves sized to AS568 specifications, compatible with systems handling petroleum products, fuels, hydraulic fluids, and other media within the fluoroelastomer chemical resistance range.

Installation Notes

Installation is typically performed by licensed plumbers, HVAC technicians, or industrial maintenance mechanics. Always depressurize and drain the system before replacing any O-ring seal. Inspect the mating groove for scoring or contamination before seating the ring. Avoid using petroleum-based lubricants on fluoroelastomer seals unless confirmed compatible with the system media; use an approved assembly lubricant consistent with the service fluid.
