Question by: Billy B on Jan 4, 2026, 6:21 AM
got a groove set up for a 7/8 inside diameter o-ring. is this the right one or am i off a size
Answer by: Customer Support on Jan 6, 2026, 8:16 AM
Match it up by the nominal dimensions. This Viton O-ring is listed as 7/8 nominal I.D. with a 1-1/16 nominal O.D., so it fits a 7/8 I.D. requirement when you are selecting by inside diameter.

Is this o-ring made from Viton, like the name says? Just want to double-check before I order.
Answer by: Customer Support on Jul 28, 2025, 6:16 AM
Yes, this o-ring is indeed made from Viton.

i’ve got an O-ring that measures about 7/8 on the inside, is this the right size one?

Fit comes down to the nominal dimensions given here. This Viton O-ring is listed as 7/8 nominal I.D. with a 1-1/16 nominal O.D., so it matches those inside and outside diameter targets.
