AirCraft Cylinder O-ring / Gasket Seal SG-COMPSP-04 For All Mini Compressors
At a Glance: Gasket-style sealing ring for the cylinder on AirCraft mini compressors—helps stop leaks and restore compression.
The AirCraft SG-COMPSP-04 Cylinder O-ring is best treated as a gasket seal: a sealing ring that sits at the cylinder interface to prevent air escaping where it shouldn’t.
On mini compressors, a tight cylinder seal is everything—if the seal is worn, flattened, or nicked, you can lose compression, the unit can run longer than normal, and output can feel weak or inconsistent.
This replacement seal is listed for all AirCraft mini compressors, making it a smart service part to have on hand when doing a cylinder rebuild or routine maintenance.
Small Seal, Big Difference: the SG-COMPSP-04 Cylinder Gasket Seal
A good cylinder seal supports stable pressure generation and helps the compressor operate efficiently.
Always match the Cat No. SG-COMPSP-04 and ensure the seal seats cleanly in the correct groove/surface.
