Did you find that somebody did a a no-no at work today Chief?

I use the aviation grade Permatex...the dark brown molasses like stuff on threaded diesel fittings.

Flare compression fittings are SUPPOSED to be metal to metal contact and don't need a sealant.

You must be Kreskin!!!!!!

I like that permatex also......Just make sure the cap is tight when you are done widdit
as one tray in my toolbox found out.....

I am not anal-retentive by any stretch but I Do wipe off the bottles/tubes......
when I am done......

When I see something like teflon tape on a flare fitting...I know the look that comes to my face.....It is the one that Oliver Hardy used to give to the camera in the olde Laurel and Hardy movies "MMMM-MMMPH well Stanley....ths is another fine mess you got us into!!!!MMM>MMMM>MMMMPH!!!!!!!!!!

Flare Fittings

You know... after doing a bunch of HVAC (R134a only) and propane work, I almost wish the entire world was flare fittings.

I actually enjoy cutting the tubing and getting a perfect little flare. Call my crazy, but it's kind of fun!

I'd expand upon the Chief's advice:
To Boat Owners (& others) >>> DON't USE SILICONE
unless you know what you're doing.
silicone is almost always the wrong product.

I understand it is most suited to fixing the first mate's front bumpers...

And... adding to Gord's caution, I have to say West Marine has a very good primer regarding sealants in general:

West Marine: West Advisor

If you are in the store, they have a handy little chart next to the sealants that shows you which materials and applications certain sealants are best for. You really can't go wrong following their advice.

For instance - I used a product I had never used before sealing up my port leaks on the Catalac. The ports or "windows" on the Catalac are an aluminum frame with thick, tempered safety glass shimmed in. This type of arrangement requires the window to be glazed, just like an automobile window or other glazed window.

The chart in West Marine directed me to LifeCaulk's Clear product, which worked fantastically. It was recommended to seal aluminum to glass in the chart. Perfect for my application.
