AIRCRAFT Cylinder O-ring For All Mini Compressors

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 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.

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.
