Arrowmax AM-931014 Oring 7X1 (10) — 7x1 O-ring pack for RC gear diffs  [AM-931014]

Practical 7x1 O-rings for RC gear diffs

This Arrowmax AM-931014 Oring 7X1 (10) is a small pack of replacement O-rings supplied for scale RC gear differentials and related small fittings. The set contains 10 pcs of 7x1 O-rings sized for common sealing grooves found in 1/12 and 1/10 pan car geardiff assemblies.

Use these rings when rebuilding or servicing diffs to restore sealing between diff housing components and to prevent oil seepage. Check the groove for debris or burs before fitting and replace any O-ring that shows cuts, flattening, or hardening.

Installation tips: seat the O-ring into its groove without twisting, apply a light smear of silicone grease to help position the ring and reduce pinching, then assemble components and verify smooth gear movement. Avoid contact with strong petroleum solvents which can accelerate rubber aging.
