Pan Car 7x1 O-ring Pack (10) - Arrowmax AM-931014  [AM-931014]

7x1 O-rings for small scale gear diffs

This Arrowmax AM-931014 Oring 7X1 (10) is a compact set of ten 7x1 rubber O-rings made to seal gear differentials and small fittings commonly found in 1/12 and 1/10 pan car diff assemblies.

Use the rings during diff servicing to restore proper sealing between housing parts and stop oil seepage. Inspect grooves for dirt or burrs before fitting and replace any O-ring that shows cuts, flattening, or hardening to maintain reliable sealing.

Assembly tips: seat the O-ring flat in its groove without twisting, use a light smear of silicone grease to help position and protect the rubber, then reassemble and check that gears rotate freely. Keep rings away from strong petroleum solvents which can speed up rubber deterioration.
