Question by: Tony T on Jan 3, 2026, 2:34 PM
Got an older RC-Series cylinder on the shelf already. These new RC-506 units gonna line up with it thread-wise and dimension-wise, or am I looking at having to redo my whole setup?

Same external dimensions and threads as the prior RC-Series, so swapping in an RC-506 won't require any rework on your existing fixturing or connections. Enerpac kept those details unchanged on purpose so shops running older RC cylinders could upgrade without headaches. The collar and plunger threads are also there for fixturing if you need them, and the new unit ships with a CR400 coupler, dust cap, and collar thread protector right out of the box.

got a couple older RC-Series cylinders already. is this RC506 gonna match up with the same dimensions and threads?

Good news if you are swapping from an earlier RC-Series model. The RC-Series model numbers, external dimensions, and threads are unchanged from prior RC Series cylinders, so RC506 keeps the familiar fit.
