google local pipe fitting suppliers chum .
theres a good few round by you.
best fittings excellent service though, if you can wait a day or so for post
ps not familiar with your set up but the supplier may ask if you want tapered thread or not .
i assume, if a dowty washer is used then the fitting is not tapered , perhaps some one could confirm....
