chrispot Posted November 19, 2016 Share Posted November 19, 2016 Hi all, can anyone confirm that a AN fittings use a 60 degree thread angle which i think it is, I have searched the net and can can't find anything to confirm. Being a yank defined thread I assumed a 60 degree, same as there NPT fittings and our BSP is 55. The reason for asking is i am making a AN fitting for a turbo oil pressure gauge. so when i fit my ball bearing turbo i can check pressure into turbo and adjust if necessary via hole size in restrictor then remove my adaptor. I know i can buy one, but why when i can make for nothing that's only going to be used once. Thanks in advance Regards Chris. Link to comment Share on other sites More sharing options...

chrispot Posted November 19, 2016 Author Share Posted November 19, 2016 (edited) Found the info if anyone interested, it is 60 degrees. Found out the std that they use is MIL-S-8879 (military std) and uses the UNJF which is the same as UNF but with a larger root radius for strength in a nutshell. Regards Chris.
