-220 BLACK CHLOROPRENE 70D O-RING

An o-ring compresses into its gland to block fluid or gas migration across a joint.

Expect good resistance to mild acids, ozone and weathering, and sunlight and salt spray. That behavior comes from the compound itself: Neoprene (Chloroprene) offers a balanced combination of oil and weather resistance, good resilience across a moderate temperature band. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). It should not be specified for service in aromatic hydrocarbons or strong oxidizing acids.

It sees regular use in general industrial, weather sealing and enclosures, and HVAC and refrigeration.
