Had a bit of fun this afternoon . . . While BES are a great supplier of reasonable price SS Fittings, I am not particularly impressed with the quality . . The 1/2" 150lb fittings and the 1/2" BSP half nuts that I am using in particular are a real PITA to use.
The first issue is the 1/2" nuts you simply cannot screw them onto 1/2" nipples then are incredibly tight . . . and on brass they actually cut new threads and cross thread. :evil: . The 1/2" Right Angled Fittings were ok, but on one of them the thread was just too short to allow the JG fittings to screw in and seal :nono: :nono: . . . . . . . So I visited Chronos, and got myself a 1/2BSPP Bottoming Tap and a Second Tap and recut the threads. . . . As I discovered though its quite difficult and I ended up with a Nut stuck on the Second Tap . . . So off to Screwfix and purchased an engineers vice . . . and I managed to free it off . . . although it did make altering all the nuts fairly easily. . . . and now they all thread easily onto a 1/2" nipple. Should make assembling the ball valves and sight tubes easier.
