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.
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.
Features
Features
- Gasket-style sealing ring Designed to seal the cylinder interface and prevent air leaks.
- Service replacement part Ideal for mini compressor maintenance and cylinder rebuilds.
- Flexible elastomer material Provides consistent contact and sealing when correctly seated.
- Listed for all mini compressors Part-number referenced fitment across the AirCraft mini compressor range.
Benefits
- Restores compression: Helps prevent pressure loss caused by leaking cylinder joints.
- Improves efficiency: A proper seal can reduce run time and help the compressor reach pressure faster.
- Smoother performance: Reduces “weak output” behaviour often caused by internal leakage.
- Protects components: Less leakage means less heat and strain from overworking to compensate.

Extra Info
Extra Information
- When to replace: If the seal is flattened, cracked, stretched, or shows cuts/nicks, replace it.
- Clean seating surface: Remove old residue and ensure the groove/surface is clean before fitting.
- Pair with cylinder service: Often replaced together with the cylinder sleeve during a rebuild.
- Confirm fitment: Although listed for all mini compressors, always match SG-COMPSP-04 to your parts list.
Pro Tip
- Lightly lubricate the seal with a compatible lubricant before installation (where appropriate). It helps the gasket seat properly, reduces pinching, and can improve sealing on the first assembly.
Safety
Safety
- Disconnect power and remove the battery (if applicable) before servicing the compressor.
- Allow the unit to cool down before disassembly—mini compressors can get hot during use.
- Work in a clean area to prevent dust entering the cylinder and seal surfaces.
- Avoid sharp tools that can damage the sealing groove or cut the new gasket seal.
- After assembly, test in a controlled manner and check for abnormal noise, heat, or loss of pressure.
