Also hows the best way to attach a fitting if it needs to be in a certain position but the threads aren't tight enough. I have a squeeze bulb priming system and I need the fitting to point in a certain direction. When tight they are not in the right direction. What to do??
I have run into this and one way is to use JIC hydraulic fittings.* A straight adapter with a male jic taper on one end and a pipe thread on the other.* The pipe thread screws into the port you have.
Then an elbow with* with a swivel female jic end on it and a female pipe thread on the other.* The two jic will align in any direction you want and when tightened are leakproof and will not loosen.** Then you can use any pipe thread hose end you want in the other end of the elbow.
Take a look at the two link I've shown to see how they work together and figure out the sizes you need..** Most hydraulic fitings mfgrs. will offer these. There are many other combinations allthough*it will take a lot of looking.* If you*have a hydraulic supply house nearby they should be able to help particularily if you print out the photos.**
*i didn't look but they may be available from someone like McMaster Carr.
