SS-10.5 O-Ring Seal for RC Engines OS29701310 by O.S. Engine  [OS29701310]

Sealing part for model engines

This O.S. Engine component, model OS29701310 with SS-10.5 GT55 identification, is an O-ring designed for use in engine-related assemblies to reduce seepage of fuel and lubricant. It is a serviceable seal intended for hobby engine maintenance.

To fit: verify mating surfaces are clean and free of burrs, ease the O-ring into place without overstretching, and perform a static pressure check when possible. Avoid contact with solvents that degrade elastomers and store spares in a dry environment out of sunlight.

In service routines, consider the O-ring a replaceable item: check its condition during tuning or rebuilds, replace upon any sign of fatigue, and keep extras on hand to shorten field service times. Ensure correct groove sizing when sourcing replacements.
