About truck air compressor repair kits

The air compressor supplies all the compressed air the braking system uses. Valves, gaskets and seals inside the compressor head control efficiency and oil carry-over.

When to replace

Slow build-up, excessive oil in the air system, knocking or air leaking from the head gasket indicate compressor wear.

What's in the kit

Compressor kits cover reed valves, head gaskets, unloader parts and seals for a wide range of truck and bus compressors. All 9 compressors lines are manufactured by Pitchline Engineering in an ISO 9001 environment in Pinetown and supplied from our Pinetown branch across South Africa.
