When you guys plumbed your adapters in to the master cylinder what did you use as a thread sealant thanks .rusty

[EDMO 1078]

Loctite 545 hydraulic sealer. I also use this as a medium thread-locker/protectant sealer for bolts.

You do not need to use heat to remove fittings or bolts.

I have used Loctite 565 and 569 with excellent results, although EdMO's 545 is probably a better choice.  I just happened to have 565 and 569.  I have heard not to use PTFE tape because of the ability to create a hazardous stoppage.

We used Loctite 545 on all hydraulic and pneumatic fittings and non-stainless bolts in the Coast Guard when I was a maintenance supervisor, since there is a lot of corrosion on boats. Liquid PTFE sealant was used on some water lines, but never the tape.

We used the liquid PTFE (Teflon) on pneumatic fittings at Chrysler. The PTFE Tape sheds strings which can get into air and hydraulic valves and cause a lot of trouble.

No sealant should be on the first two threads of a fitting.

Most will caution against tape, but that is because very often it isn't used correctly.

It gets wrapped in the wrong direction, not tight enough and as Ed mentioned, too far to the end of the fitting. In my career, I have seen droplets of sloppily applied liquid sealer cause blockages, too.

Care must be observed with fitting sealer products of any type.

Is 545 sold at auto parts stores? I need to reseal a fitting in the steering box of my rock crawler.

[EDMO 1078]

I donno - I got mine thru Coast Guard supplier.

Check shops that sell hydraulic fittings and hoses.

Or, check Loctite for a dealer near you.
