BSPP (British Standard Pipe Parallel): With parallel threads, BSPP offers a reliable and versatile option for various applications. It’s commonly used in low-pressure applications where a tight seal is required.

Parallel threads can be called BSPP or GAS threads, abbreviated as “G“. They are threads designed for gases. The internal and external threads of a parallel thread are sealed with the help of an O-ring to prevent fluid leakage.

British Standard Pipe (BSP) threads are renowned for their precision and dependability, yet they come with certain limitations that might be relevant in particular scenarios:

  ●Potential Leakage: The characteristic rounded peaks and valleys of BSP threads can be both a strength and a weakness. While they offer unique sealing properties, if not correctly sealed, they might not provide a robust metal-to-metal contact. This could lead to potential leakage, a concern, especially in applications involving high pressure.

  ●Limited Availability in Certain Regions: While BSP threads are standard in many parts of the world, they may be less common in areas where NPT threads prevail, such as the United States and Canada. This limited availability might lead to delays in procurement or an increase in costs, affecting project timelines and budgets.
