Class for pipe fittings is a standard defined by the ASME/ASTM. Though stated with a # sign, such as 150# or 3000#, it is not a direct pressure rating.  The pressure rating is dependent on material and temperature and is found by consulting an appropriate reference guide.


Threaded couplings go on threaded pipe. Socket Weld couplings go on plain end pipe.


Full couplings are intended to join two pieces of pipe together. Half couplings are used to make a branch connection instead of using a sockolet or thredolet.
