In service, this o-ring compresses into its gland to block fluid or gas migration across a joint.
The material holds up against many alcohols, hydraulic fluids, and petroleum-based oils. Buna-N (Nitrile) offers strong abrasion and tear resistance, the most widely specified general-purpose sealing elastomer. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). It is not the right choice where ozone and direct sunlight or automotive brake fluid are present.
This item is metal detectable for HACCP and foreign-body control programs. You will find this material specified across agricultural equipment, automotive, and general industrial maintenance.
H70MD174 ships individually. Nominal inside diameter is listed as 8 3/4 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
