Help with connecting Brakemaster air line to Relay Valve

[phinneyj]

I am working on installing the BrakeMaster 9160 in my MH. I am trying to install a Tee fitting in the Relay valve so I can tap it with the Supplemental Brake Air Line. Here is the picture. Neither 90 degree fittings want to budge. Any ideas?

First spray a little Blaster or any good penetrating oil on the treads (both). Try not to get it on the rubber hose. Next use one hammer head as a backup on one side of the hose fitting then tap on the opposite side of that fitting which will help the oil to work down the threads. Doing this a couple of times you should be able to break the hose fitting loose but don't take it all the way off yet. Next tap the 90 degree fitting towards the valve working the oil into the threads then try to break it loose. By leaving the hose fitting on a little if you miss you won't damage the threads. It should come loose if not give it an hour or so for the oil to work and try it again. Good Luck!

Thanks, I will give it a try. My neighbor happened to have a can of Blaster he lent me. I have been spraying it, just not the extra mechanical application. Thanks for the keeping it off the hose warning. I needed to replace those anyways.

....and now for the follow up. Using Blaster and a little persuasion I managed to get the fitting off, install a Tee and reinstall everything and connect the Brakemaster brake line. Here is the lesson. The picture above is for the Parking Brake relay valve. So, to make a long story short. After identifying that I tapped into the wrong port I returned the valve to original condition and started anew. After properly testing for the right port to use I made the appropriate connections and all works as advertised!!

Here are some of the pictures from the installation of the base plate. The difficult areas are penetrating the firewall and installing the breakaway system air reservoir.

A trick to fittings with pipe thread, tighten the fittings in other words turn the fitting like you are tightening it as soon as it moves stop and remove it it will come out easy
