Overhaul & Repair Kits

ASC overhaul kits include only the finest quality precision parts, seals, bearings, gaskets and O-rings. Turbine air starters such as ASC or by makers like TDI, require an accurate balance of components with precise specifications functioning together to deliver high performance.


ASC is committed to the use of high quality shaft seals. These critical components use an interference fit that seals statically against the housing bore and a sealing lip,  which seals dynamically and statically against the turbine shaft. 


ASC uses high quality, low-friction bearings optimized for low noise and low vibration enabling high rotational speeds.


O-rings seals must meet exact specifications for reliable service and safety. That's why ASC o-rings are manufactured to ISO 9001 standards.  ..
