Mr Blue Sky Posted July 9, 2019 Report Share Posted July 9, 2019 Hi All, I am replacing the pattern master cylinder with a refurbished original Lockheed master cylinder. The problem I have is that my pipe fittings are UNF (3/8" & 7/16") and the outlet ports are BSP (1/8"). While I can replace the 1st section of the brake system with a mix of 1/8" BSP and 3/8" UNF fittings, the clutch pipe is a different issue. Does anyone know where I can get a union which is 1/8" BSP male and 7/16" UNF female? If I can get an union that does the brake line too, so much the better. Any help and/or guidance gratefully received. Thanks and regards, Laurence Quote Link to post Share on other sites
Charlie D Posted July 10, 2019 Report Share Posted July 10, 2019 Laurence There is a place just down the road from you in Hereford. https://www.tech-hose.co.uk/ They stock just about anything you can think of that has a use in hydraulics. They claim to have a catalogue of over 48,000 products. (If you visit their trade counter they seem to have them all on display!) The biggest problem is trying to find what you need on their site.Maybe try here first: https://www.tech-hose.co.uk/products/adaptors-fittings/brass-adaptors/ Charlie.

BlueTR3A-5EKT Posted July 10, 2019 Report Share Posted July 10, 2019 ....not 1/8" BSP tapped outlets on an original master cyl surely? I think you will find it is BSF. I have the male tube nuts somewhere as I used to make up adaptor pipes for TR2/3 to accept modern UNF threaded master cyls. 7/16 x 18 and/or 3/8 x 20 BSF. like the wheel cyls PM me if you want me to go on a garage search for a tube nut.

Mr Blue Sky Posted July 11, 2019 Author Report Share Posted July 11, 2019 Hi Peter, I tried tech hose and they can come up with a Heath Robinson affair of a couple of different adapters, but they will be special order. If you do have a tube nut, I'd be happy to buy one off you plus postage and packing. Let me know the damage and I can arrange payment. Regards, Laurence Quote Link to post Share on other sites

Regards, Laurence Laurence, Yes I have touched all the pipe nuts I have. PM me with your address and I will get them in the post. I have also sent this to you as a PM so you can simply reply Cheers Peter W Quote Link to post Share on other sites

Regards, Laurence Laurence, Having now looked at the book I suspect it is item 3 in the picture you are after with a 3/8" BSF external thread and a 7/16 unf internal to screw into your original master cylinder. ....Yes? On the pic are the items I have. None are BSF, which would fit the master cylinder. I do have the tube nuts that fit on the brake/clutch hydraulic pipes in 3/8 BSF & 3/8 UNF & 7/16 UNF and 1/2 UNF. both male and female. The banjo arrangement is TR4A << https://www.moss-europe.co.uk/shop-by-model/triumph/tr2-4a/clutch-transmission-drivetrain/clutch-systems/girling-clutch-hydraulics-tr4-4a.html >> I think, a straight adaptor is also used on T type, but I do not know its thread sizing. https://www.moss-europe.co.uk/shop-by-model/mg/t-type/brakes/brake-controls-hydraulics/brake-system-td-tf.html The double ended adaptor is from Girling clutch master so is UNF threaded both ends.
