  • threading BSPT with 141

    I have a model 141 threader and bought BSPT dies for it and now I am finding that it won't thread the pipe properly because the gears/threads on the 141 are set to 8 TPI. Do I have to buy a separate 141 for BSPT threads? Unfortunately I do not have the time to wait to buy another 141 and do not want to spend the money (Ha!) but I am wondering if anyone nows how to set this 141 to thread the BSPT (which are 11 TPI)??

    Anything would help!

    To convert your 141 NPT to 141 BSPT you need a BSPT Workholder, a BSPT Threaded Barrel, and a BSPT Selector Plate. These 3 parts along with the dies will make your 141 do BSPT threads. The only other way is to buy the 141 BSPT new.
