AirCraft Air Angle Grinder Service Kit O-ring And Washer For AT0013 125mm Proline (AT0013-SK12)
At a Glance: O-ring and washer seal kit for the AT0013 Proline—refreshes critical sealing points to help stop leaks and maintain consistent performance.
Air tools are simple creatures: give them clean air, the right lubrication, and good seals—and they’ll work like a champ. The AirCraft AT0013-SK12 Service Kit is an O-ring and washer set for the AirCraft AT0013 125mm Proline air angle grinder. It’s designed to replace the small but crucial sealing components that keep pressure where it belongs. Over time, O-rings harden, flatten or nick during servicing, and washers can wear or deform—leading to annoying air leaks, inconsistent power and rough running. This kit helps restore airtight assembly so the grinder runs smoother, quieter and more predictably.
When seals are right, airflow is controlled properly and the tool performs as intended. When seals are tired, everything feels “off”. This kit is the quick fix that makes a rebuild worth doing.
