Welding Tips and Tricks

this is from a flowmeter.. female 5/16-18 and female 9/16-18 (not 100% sure on 9/16 size)
I need to purchase just this part but I cant find it anywhere online. only matching sizes like both are 5/16-18. they are pretty common on most flowmeters and regulators I believe but like I said I cant find just this part anywhere.. anyone feel like helping me locate it and providing a link ??
thanks

sorry all but good news, I think I just found it at airgas

for future reference look up the catalog at Western Enterprises Industrial Products to find part numbers and distributors

Cool, thanks for the website. I have bookmarked it!
