7x1 O-ring Spare Pack (10) for Gear Diffs - Arrowmax AM-931014  [AM-931014]

Replacement 7x1 O-rings for gear differentials

The Arrowmax AM-931014 Oring 7X1 (10) supplies ten 7x1 rubber O-rings intended for sealing the tight grooves used in 1/12 and 1/10 pan car gear diffs and related small fittings.

Fit fresh O-rings during diff strip-downs to re-establish oil-tight joints and prevent seepage that can affect gear and bearing life. Before installing, clear the groove of any debris or sharp edges that might cut the new ring.

Fitting advice: place the O-ring flat into its groove without twisting, use a light film of silicone lubricant to ease placement and reduce the chance of pinching, then reassemble and verify free gear movement. Do not use harsh solvents on the rubber as this will reduce service life.
