I have 2 Sharp machines that use metric push-to-connect air fittings. 6 and 8mm OD tubing.
The machines are 15 years old now, and I seem to be dealing with more and more leaks every year, I'd like to go through and replace everything.
My confusion is in the fittings. They are all 1/8" size threads, but they are available in BSPT, BSPP, and "universal". To add to the confusion I have also found 6mm fittings with 1/8" NPT.
I've used the 6mm universal elbows from mcmaster and they do not leak, but I could save a little money if I knew what the threads really are.
So on Taiwan machines that use metric air tubing, is one thread considered the "standard" that you would normally expect to see? Or is it a total crapshoot?
I've ordered a couple elbows with BSPT threads, and I'm thinking that's what they typically used. There are members here who have a lot more maintenance experience than me so I'm hoping for some insight so at least my guesses have a chance of being correct!
