Accepted formulae relating torque and tension, based on many tests are:M = P x D M = torque lbf.ft 60 P = bolt tension lbf D = bolt dias Or for metric sizes:M = P x D M = torque N.m 5000 P = bolt tension Newtons D = bolt dia. mm These formulae may be used for bolts outside the range of the tables overleaf.
Assembly / Installation - Parker HannifinNote:Lubricate threads before assembly! Values in chart are for steel ttings in steel ports. For stainless steel ttings, please use the upper limit of torque range. For brass (and other soft metals), decrease torque value by 35%.

These Specifications are for carbon steel. With Zinc plating always lubricate threads and seals. For stainless steel, use the high value of the torque range of steel. For brass, use 70% of the torque value of steel. For mixed metals, use the torque of the lower of the two metals Torque range is normally calculated +/- 10%.

Threaded Fitting Installation GuideThreaded Fitting Installation Guide Use of Teflon tape is recommended on all plastic pipe threads wrapped 2 to 3 turns around the male thread before assembly. A simple rule of thumb for installing tapered pipe threads, both metal and plastic, is finger tight plus one to two turns with a wrench.
Included in the standards for NPT threads and ANPT threads are engagement length, both straight and wrenched. For example, a 1/4 inch tapered pipe fitting should screw in 4.1 threads until finger tight (hand tight engagement), and 3 threads for wrench makeup. One problem is the wide variance in quality of the fittings and threads.

Torque for NPT connections - Pipelines, Piping and Fluid Jun 22, 2005 · My guess is around 10-25 ft.-lbs. torque for a 1" NPT. pipe thread. This is the torque range of a bolt that is about 1/4" in diameter, which is about 1/2 the amount of steel material that the 1" NPT has, but the pipe geometry is a cylinder.
Feb 26, 2020 · One discussion that comes up quite frequently is torque specs and then the torque spec for a tapered thread. In case you were not aware, the NPT or BSPT (male) inlets on EXAIR products are both a tapered thread. Tapered threads are generally used on pipe fittings under pressure to seal better and provide a secure engagement.
