I'm making a brake line tee for a guy , and I'm having trouble getting an acceptable fit . The compression nut reads 9.85 mm x 1mm pitch . The tap I bought measures 10.10 ... and the nut is way too loose in the threads . I'm wondering if this auto parts store tap is oversize ... might be OK for a bolt thru a bracket or something , but I'm not using it for this job . Is there a chart somewhere that has size data for taps by fit class ?
