    Diameter: 1. The diameters are given in inch fractions. For example, 1/4″, 3/4″, 1 1/4″. 2. It is also allowed to denote the diameters with a decimal value. For example, 0.250 (1/4″), 0.4375 (7/16″), etc. Pitch: 1. By default, the pitch is given in TPI. For example, 1/4-20 means a thread with a pitch of 20 TPI (1/20=0.05″). 2. It is also allowed to...

    NPT stands for National Pipe Tapered threads. The basic profile is a 60° truncated triangle similar to the Unified Inch threads (UNC/UNF). The main difference is that the thread profile is tapered at an angle of 1°47′ (0.75 in/ft or 62.5 mm/m) relative to the axis. The taper on NPT threads allows them to form a seal when torqued as the flanks of th...

    NPSC Internal Straight (parallel) Pipe Threads are used to manufacture pressure-tight fittings when assembled with an NPT external taper thread. This series applies to internal threads only. (The external thread is the standard NPT thread).

    The NTPR thread is used to connect Railing Joints that require a rigid mechanical connection, such as stair railings.

    The NPSM thread series creates a non-pressure tight connection. It is mainly used in mechanical joints and special applications with no internal pressure and, consequently, no sealing requirements. It is possible to achieve a seal with the aid of an O-ring. 1. The profile form is similar to that of UN threads. 2. The allowance and tolerances are id...
