At a Glance: Essential replacement O-ring seal to help keep your Air Ratchet Wrench airtight and performing at its best.
Small seal, big impact. The AirCraft AT0016-02 O-ring is a purpose-made replacement sealing ring for the AirCraft Air Ratchet Wrench (AT0016 series). O-rings are the quiet heroes inside pneumatic tools—keeping compressed air where it should be, maintaining pressure, and preventing annoying leaks that steal power. Whether you’re doing a service, fixing a slow or inconsistent tool, or simply stocking spares for the workshop, this O-ring helps restore proper sealing so your air ratchet can run smoothly and reliably.
AirCraft spare seal designed for dependable pneumatic performance
Correct sealing reduces air loss and helps internal components operate as intended. Replacing worn, flattened or cracked O-rings is one of the quickest ways to bring a tired air tool back to life.
Extra Information
Intended as a spare part for AirCraft Air Ratchet Wrench assemblies (AT0016 series).
Replace O-rings if they appear flattened, brittle, cracked, nicked, or swollen.
Match the old O-ring size before fitting if the tool has multiple seals of similar appearance.
If a parts diagram or service document is available in the Documents tab, use it to confirm location and quantity required.
Pro Tip
Lightly lubricate the O-ring with pneumatic tool oil before installation. It prevents twisting/pinching during assembly and helps the seal last longer.

Benefits
Restores power and consistency: Better sealing helps maintain proper air pressure for smoother operation.

Safety
Disconnect the air supply and bleed remaining air pressure before opening the tool.
Wear eye protection when removing covers—springs and small parts can pop free.
Use only a small amount of pneumatic tool oil; excess oil can attract dirt and affect performance.

After reassembly, test the tool at low pressure first to confirm correct sealing and operation.
