Yes they make a variety of galvanized and brass fittings for this....

I would recommend however that the backflow be installed differently, especially if you are in a state that requires the device to be tested.
In the interim...use a 1/4 inch street ell...male threads on one end of the 90 and female on the others...

Hey instead of using the test cock which isn't the best way to blowout a system. On the downside outflow of the backflow cut out a piece of pvc and install a 1x1x3/4 or 1/2 tee. You can then use that to blowout your system with no problems from now on. Don't forget to buy a 3/4 or 1/2 plug as well make sure its threaded the tee and the plug.

<br />The guy who installed my back flow (Febco 825Y) put it on so the test cocks are facing the house. Problem is that only gives me about 2 inches to connect my compressor. I can't get the 1/4" connector on and fit my compressor hose in that space. Does anybody know if there is a 1/4" 90 degree fitting. Or any other thought you might have. I am all ears.

Backflows are not there for irrigation blow-outs!
