Need help with Seatech fittings

I have a 1995 PSC 37. According to Thumper at PSC the potable water lines used at time of building were either Seatech or Whale.

Mine appear to be Seatech but I can't figure out how to disconnect the fittings.




This first photo is of one of the connectors.



Sorry for the crummy pic. This is after popping the end cap off. I had assumed you push the gray collar toward the fitting but I was unable to get it to move.

Any help is appreciated.

Thanks

Dale

I would assume, I don't know that they were like a electrical shrink fitting. Meant to last as
long as they last. Cut them off and replace them.

Zen is a matter of recognizing reality.

The ring on the right in your photo (blue arrow) is a protective cover to prevent accidental disengagement. Once it's off, you push the ring on the left (red arrow) in while pulling the tubing out to disengage. The system must be de-pressurized to get it apart.

I suggest a wrench as the best way to press on the ring. You might have to jiggle the hose a bit, it's been in there for a while and it's happy where it is.

Try this : While pushing on the ring with the wrench, push the hose in further, then pull hard.

Re: Need help with Seatech fittings

I know the "Gator fittings" and "Shark Fittings" have a tool that snaps over the tube, and you use that to push the ring into the fitting. You might check Home Depot or Lowes to see if they have a tool that would fit. It will come undone, but if it has been on for a while I would not think it will seal again because the O-rings will likely have deformed. They seem to be connect several times while setting them up, but once on for a year or two they won't disconnect and re-connect without leaking. Or so it has been my experience, especially if it is a hot water line.

Likely would work. I don't like the fittings in a house where they are hidden but on a boat they would work well. I have used them in a house, but only over a drop ceiling where there is good access if it ever needs to be replaced. I prefer the crimp fittings, and once you have the tool they are much cheaper.
