hi, I need to replace a hose on 1of my trim tabs. Im using a boat leveler pump but unsure how to disconnect the hose at the tab. There seems to be a sleeve crimped over the hase at the cylinder. Any ideas?
thanks jim

Yep, it is crimped with a 12731 collar clamp. Part sells for less than three bucks but the pneumatic clamp tool is probably six hundred.

Cut the old hose off the cylinder. Slice the crimp sleeve with a utility knife and peel it off. Replace the entire hose from the pump end, which has a standard threaded fitting, as recrimping requires a special tool. To the best of my knowledge this is what I feel should help solve your issue.

sounds like its cheaper to buy new cylinder with hose already attached

I see that hose connections are being made with this crimp ring along with a new cylinder. I have these rings but wonder if you guys feel skeptical of this type of connectionhose clip.jpg

If it’s a barbed fitting it should work. If push comes to shove take it to a hydraulic shop and have them crimp it. My local Napa auto parts does hydraulic lines but I’m not sure it they all do.

Those are referred to colloquially as Oetiker style clamps. They are far superior to worm screw style clamps and, with the proper size for the application, will clamp and hold as well as a crimped ferrule. Use the proper tool on them (ratcheting action where the whole crimp part is inserted into the tool), not the cheap crab-style cutter looking tool that comes with most of these kits.
