1. I hever have seen left hand threads on any brake components

2. Heat would help, but as previously posted, there are parts inside that foot valve that would not be happy.

3. If the easy out is not working, your going to have to drill it out, with a LH drill. Be very carful not to drill into the valve. You'll have to pick out the threads of the old brass fitting from the foot valve.

4. From your pictures, some of the fitting indicate that the nut on the fitting is up against the valve. I'm betting that the thread sealant you are having trouble with, was used because the fitting were not sealing properly.
Some fittings are sold with very little threads & a sealant washer.
I think they are for BSPP or BSPT and will fit in a NPT thread but will NOT seal well.

5. Take the Foot valve off & have a shop fix or get a new/reman foot valve.

Good Luck

Thanks you for your good advice!

I went to the truck parts store in Ventura and found the parts to put it back together if I get the old part out!
I got push lock male conector & push lock full union also picked up one foot of the hose to patch it!

I alled Newell and they alos sugested very low flame on the treads and try to loose it with heat.

I will try it and see if I get anywhere!

Your sugestion using drill bit is good!

I was thinking drill out the hole just bigger in the brass union to fit larger size easy out tool bit,it looks like 19/64 size would grab entire union better! and also the square end of it is way bigger and better grip to put wrench around it!

Replacing entire unit will be quite challanging for me ,I would have to mark each air line and replace one by one! I found the entire unit cost about $240 with out the brass fittings, I would have to get the model number of the old one.
