Soo you tried the the tighten till it breaks then back off 1/4 turn method? I just googled torque values there are lot of charts on line you need to watch unit as some are in in /lbs some in foot lbs and some in newton/meters

I have about 30 years as a machinist but do not have equipment any more and gave my handbooks to someone starting out.
I have snapped a couple of nozzles and had to use an easyout. So I thaught I would see if I guessed wright on the torque.

Thanks Again

An aside here if it is ok . years ago i was machining air fittings for model engines. I learned the hard way it was easier to cut the threads before drilling . If i drilled first the tread ripped off in the die .

Just do not use my older brothers method . Turn it down until it breaks then back of a 1/4 turn. He was actualy quite a mechanic 20 years on motorcycles then packaging machines for 20 plus years.

probably a good guess . some charts suggest more like 60 for a brass bolt but bolts are not hollow.

I have always just snugged the nozzle down (estimated Guess) at to tightness.
If I use a torque wrench how many inch pounds should I use.
The block is aluminum.
I am guessing 42 inch pounds does that sound about wright.

Thanks
