Zoro Select Viton O-Ring 3/8 Inch ID

These brown Viton O-rings have a 3/8 inch nominal inside diameter and a 3/32 inch cross-section. They suit automotive and industrial sealing tasks needing chemical and heat resistance. The pack contains fifty pieces for maintenance or assembly work.

Simple press fit into standard grooves

Installation requires seating the ring evenly in the gland without twisting or stretching. The 75A durometer material resists compression set but can be nicked by sharp edges during assembly. Lubricate with compatible fluid to avoid damage.

Temperature range -15 to 400 degrees F

This continuous operating range decides if the seal survives your fluid and environment. The Viton compound handles oils, fuels and high heat within these limits. FDA approved material suits food or pharmaceutical contact needs.
