Looking For Replacement Fill Cap For Tie Down 660 Actuator

Published 06/09/2026

Question:

Will this fit a Tie Down 660 actuator? Existing cap is part 70470-4 Master Cylinder Fill Cap with internal bladder, 1.25” Opening Open Models? My current cap is pretty flush with the actuator so worn out and like this raised design.

Hey Tom, thanks for reaching out. We don't have a filler cap specifically for the Tie Down 660 actuators, but the # DX39VC cap you mentioned is for a 1.25" opening so if that's what your actuator uses it should work. It's not something we have physically tested though, but I think it's worth a shot.
