25" O-Ring
Most orders placed before 3pm will be dispatched the same day on a non-guaranteed Next Working Day delivery service. Read our Delivery Guide for details.
O-Rings are located in a groove between the rim & bead seat ring to create an air seal on 3 & 5 piece grader, earthmover and OTR wheel rims. The THICK o-ring versions tend to be 9.5mm or 3/8" in their cross section, whilst the THIN variants are around 6.5mm or 2/8" in cross section. This 25" THIN version is often referred to by manufacturers as OR-225 (where OR stands for 'o-ring', the first 2 refers to it being 2/8" thick, and the remaining 25 referring to it being 25" in diameter).
