SPEEDAIRE Piston Set for Air Compressors

This SPEEDAIRE piston set contains two replacement pistons designed for compatible air compressor pumps. It suits maintenance technicians and workshop owners who need to restore compression performance on specific Grainger or Speedaire units. The pack quantity of two matches twin-cylinder pump configurations.

Direct replacement with California Proposition 65

Installation involves removing the cylinder head, extracting worn pistons and fitting the new set with fresh rings and gaskets. Common issues include damaged cylinder bores that require honing or sleeve replacement, and misaligned connecting rods that cause premature wear. The product carries a California Proposition 65 warning for chemicals known to cause cancer and reproductive harm.

Limited to specific Grainger

These pistons are confirmed compatible only with Grainger part number 11X292 and Speedaire pumps where the series is listed as not applicable. They will not fit pumps from other manufacturers or different Speedaire series without verified cross-reference. Buyers needing pistons for unlisted models or higher-displacement pumps must source alternative parts.
