Thanks for all your replies. All threads ect all in perfect order, tightens up perfect but just seems to work free. I have never had this issue before and usually copper grease all fittings to help with removal later which is why i was unsure as to the use of loctite on something i know will cause me hassle later.
Would love to put some pics up but only seem to be able to put in my gallery but if any one can tell me where im going wrong i will add some.
