Compatible Maintenance Kit
The SPEEDAIRE 56604 Bowl and O-Ring Kit Intermediate provides replacement seals for specific air compressor lubricators. It fits Grainger part numbers 4ZK86, 4ZK88, 4ZK90, 4ZL33, 4ZL35, 4ZL37, 4ZL39 and 4ZL41. This new kit suits technicians maintaining compatible Speedaire lubrication systems. It is not for compressors using different bowl or o-ring specifications.
Operational Reliability
Fresh o-rings restore the seal between the bowl and body to prevent air leaks during normal operation. A secure seal maintains consistent lubricant delivery without pressure loss. The bowl holds lubricant under system pressure without deformation. No noise or power-draw figures are provided for this passive component.
Included Components
The package supplies the intermediate bowl and the matching o-ring for direct installation. No additional tools, lubricants or software are bundled with this kit. Installers must provide their own wrenches and thread sealant if required. The parts enable immediate service once the correct compatibility is confirmed.

Questions about this item
How do I install the SPEEDAIRE 56604 bowl and O-ring kit on my compatible compressor?
Remove the old bowl and O-ring from the intermediate lubricator, then fit the new SPEEDAIRE 56604 bowl and O-ring, ensuring the O-ring seats evenly in the groove before tightening the bowl to prevent leaks.
What maintenance will the SPEEDAIRE 56604 bowl and O-ring kit require after installation?
Inspect the bowl and O-ring regularly for cracks, swelling or lubricant contamination, and replace the O-ring whenever it loses elasticity or shows wear to maintain a proper seal.
What is the first limit that appears when the SPEEDAIRE 56604 bowl and O-ring kit is used continuously under pressure?
The O-ring will degrade first under sustained pressure and lubricant exposure, losing elasticity and causing leaks before the bowl itself shows any structural fatigue.
