Yale AYS extension tubes mount onto YS cylinders via the corresponding base adaptor to extend the cylinder's reach. Yale supplies extension tubes in four standard lengths (125, 250, 500, 750 mm) across three capacity families matching the AYS-5, AYS-10 and AYS-15 base adaptors.
Add reach to Yale YS cylinders for tall lifting applications
Yale documentation states the use of extension tubes adds to the versatility of the standard cylinders. Tubes mount onto the bottom of YS cylinders via the appropriate base adaptor (AYS-53, AYS-103 or AYS-153) with two hexagon socket screws.
Suitable Applications
Per Yale: extending the reach of YS cylinders for applications requiring lifting heights greater than the cylinder's natural stroke. The catalogue example: YS-10/150 with AYS-106 extension tube and AYS-103 base adaptor for straightening of a container box.

Frequently Asked Questions
Q: How are tubes mounted?
Tubes mount via the matching AYS base adaptor (AYS-53/103/153) which bolts to the bottom of the YS cylinder using two hexagon socket screws (supplied with the adaptor). The tube then threads onto the base adaptor.
Q: Can I mix tube sizes between capacity families?
No - tube threads are sized to the matching base adaptor. AYS-5 series tubes fit only AYS-53; AYS-10 and AYS-15 tubes fit their respective base adaptors.
