Value Collection ZMSCV70145 Viton O-ring Dash 145 10-pack

Product Description

The VALUE COLLECTION ZMSCV70145 is a Dash 145 Viton (fluoroelastomer) O-ring used for static and dynamic sealing in fluid and gas handling systems. It measures 2.563 inches inside diameter, 2.75 inches outside diameter, and 0.094 inches thick with a round cross section. Shore hardness is rated at 70, placing it in the hard category. The fluoroelastomer compound delivers strong resistance to petroleum-based fluids, high temperatures up to 400 degrees F, and low gas permeability, making it a reliable choice for HVAC, plumbing, refrigeration, and industrial sealing applications. Licensed tradespeople and maintenance technicians install these during equipment servicing and seal replacement work.

This O-ring is suited for residential and commercial systems where exposure to petroleum products, fuels, hydraulic fluids, and elevated temperatures is expected. The Dash 145 designation follows standard AS568 sizing, allowing straightforward cross-referencing on valves, pumps, fittings, compressors, and manifolds that call for a Dash 145 profile. The low compression set rating helps maintain a reliable seal over extended service intervals. Each order ships as a pack of 10 pieces, supporting fleet servicing and preventive maintenance stock. The fluoroelastomer material also handles vacuum service conditions with low permeability, which extends its use to refrigeration valve assemblies and vacuum pump connections.

Compatibility

Designed as an OEM-style replacement or service seal for any equipment requiring an AS568 Dash 145 O-ring in a fluoroelastomer or Viton-compatible material, including valves, pumps, compressors, and fittings that contact petroleum products or operate at elevated temperatures.

Installation Notes

Installation is typically performed by licensed HVAC technicians, plumbers, or industrial mechanics during scheduled maintenance or component overhaul. Always depressurize and isolate the system before replacing seals, and verify the groove dimensions match the Dash 145 profile before installation. Lightly lubricating the O-ring with a compatible lubricant eases installation and reduces the risk of twisting or cutting the seal. Follow applicable codes and equipment manufacturer guidelines for torque and reassembly procedures.
