How to measure an NPT thread?
In order to identify a fitting TPNit is by convention always necessary measure the diameter at the widest part of the thread. The outer diameter will therefore be the largest diameter of the thread of the male part, and the inner diameter the largest diameter of the thread of the female part.
What is a 1 4 thread?
For the BSP, this diameter does notis neither the outer diameter nor the inner diameter of the thread (1/4“= 6.35mm), unlike the BSF and BSW (with imperial pitch) as well thatto UNF and UNC (with metric pitch), where it corresponds exactly to the outer diameter of the corresponding tube.
How to recognize a gas pitch?
The name BSP comes from English: British Standard Pipe thread. also called Not from Gas (Where No Gas), this thread is distinguished by its fine thread.
How to find the right thread?
the thread is the distance between the threads expressed in millimeters (measured along the length of the screw). For example, a thread pitch of 1.5 means that the distance between the threads is 1.5mm. In general, smaller screws have finer threads.
What are the different thread profiles?
What are the different No thread ?

- NOT American & English => UNC/UNF/UNEF/8UN/BSW/BSF.
- NOT Gas.
- NOT trapezoidal.
What is the thread of a gas cylinder?
The size of the threads of the devices at the gas most commonly used in France is 1/2 right on devices gasm20x150 on the regulators and ½ left on the gas bottles. The left ½ of the taps of bottle may also vary in some countries, such as Greece or Italy.
