Has anybody ever tried using a rubberized sealant to repair the
leaking hydro units? Just wondering
Thanks

Unlikely. It’s holding 350 PSI static pressure, and closer to 700 under compression to the bump stops.

Re: Hydrolastic displacer repair?
A bit late in the day, but what about this for a repair. Similar problem with an old but reasonable exterior condition hydro unit here that is weeping fluid through the lower (strut end) of the unit. Not a lot, just allows the car to drop about 1" over a full year.
I have fully flushed, vaccumed and dried the insides of the unit. I have injected deep into the bowels of the unit some of that high pressure sealant that my son uses in his VERY high pressure bike tyres and pumped the unit up with 25psi of air. Nothing to blow your socks off but certainly enough to force the sealant to find its way into the delaminated area. Hopefully.....!
Has it worked? Ain't got a clue and will never know unless I REALLY pressurise the unit (with the ends protected with a steel or wood frame) or until I find tome or the need to test it for real, on the car. As Bomber Harris once said '.......We don't know if it'll work or not, but no-ones tried it yet...'. But would appreciate comments

Re: Hydrolastic displacer repair?
With the best will in the world, I never mentioned that green slime stuff we used in the 70's but said '....some of that high pressure sealant...' And what I had was current high quality modern cycle stuff, almost colourless stuff used in sons tyres that creeps into the leak and........ Oh, never mind. But it was marginally better than your suggestion if you don't mind me saying.
