Need help to identify compression fitting

Working on 1994 boat with potable water system using 1/2" polypropylene tubing using an unusual compression-type fitting. I would like to identify the name/type and supplier for fittings.

Can anyone help?

Those are known as SYF or in laymans terms Screw You Fittings.
I had them all over my boat and think I've now managed to get them all off and into the dumpster.

Would Flair-it or Sharkbite PEX fitting work on that tubing? If so, is there any reason to match what you've got?

Re: Need help to identify compression fitting

Those are Parker fittings. They work great on low pressure lines and are very easy to install and remove. Not intended for high pressure lines. They also are not intended to be tightened down with a wrench. The scarring on the nuts in the picture indicate that is what happened and were over tightened. These are finger tight only.

Re: Need help to identify compression fitting

Thanks for the input!

The fittings certainly look similar to the pictures I found for Parker O-ring/grab ring tube fittings. However, the spacer-ring/o-ring used in the Parker fittings looks to have a different shape from the similar hardware in these existing fittings. However, I guess this could just be age.

I will buy a few to see if they match.

In any case, all of these fitting probably need to be replaced with something more up-to-date - but for now I just want to fix a couple leaks...
