However, other series, such as NPTSC and NPTR, are also defined by this document. There is no such This document provides specifications for the Whitworth pipe thread standard according to DIN ISO 228, also known as the British Standard Pipe (BSP) thread. 1 The most popular series is Tapered Pipe Thread (NPT). Bsp basically includes two BSPP G 5/8 : Brith Pipe (BSP) Thread Dimensions and Tolerances. Some important notes from the ISO 228 - 1 standard: - Both internal and external threads are parallel threads. 5 Make a thread manually with the thread button Point 1 seems not to be connected to the new threads (There is no BSP-Table to add values). BSP and NPT threads are not compatible due to the differences in their thread forms, and not just the fact that most diametrical sizes have a different pitch. 25 inch : Thread Type BSP : Item Weight 0. 28 g : Product Dimensions 3. It is a measure of how securely a fastener is held in place. BSPP threads conform to several important standards, ensuring consistency and compatibility across various applications: ISO 228-1: This international standard specifies the requirements for parallel threads without a sealing surface, ensuring that fittings meet global compatibility. Parallel pipe size Thread size Threads per inch British Standard Pipe Taper Thread (BSPT) has been adopted internationally as a standard scale used in plumbing fittings, and it is defined by BS EN 10226-1, BS EN 10226-2, and ISO 7-1 (GB/T 7306. EN 10226-1: Pipe threads for thread-tight joints (equivalent to DIN 2999 Rp). It is the North American equivalent of the ISO metric thread system. Find the TPI, major and minor diameters, and tap drill sizes for BSP and BSPT Learn about BSP, a British standard for pipe threads used outside the USA. Can you convert BSP to NPT? NPT threads are angled at 60 degrees while BSPT threads are angled at 55 degrees, which British Standard Threads BSW BSF BSPP BSPF BSPT NPT . 2, Identify the size of a BSP thread fitting. the JIC or Joint Industrial Council thread originated in the United States. NPSC (American Standard Straight Coupling Pipe Thread) is an example of a non-tapered thread. 4 mm) of a steel tube for which the thread was intended, but is in the modern metric version of the standard simply a size number. Parallel (BSPP) The parallel thread form of BSP is also known as G-thread or Bsp Bspt Thread - Free download as Excel Spreadsheet (. Gauge diameter: Major diameter of the external or internal thread at gauge plane. BSP is primarily used in Europe, Asia, Australia, and New Zealand, and is available in two versions: Parallel (BSPP) and Tapered (BSPT). Thread Profile: The threads are designed with a 55-degree angle, consistent with the Whitworth thread form. External Pipe Threads per. Measure the BSPT male thread OD and female thread ID at the first full thread near the end of the fitting. Common symbols used for the thread: BSPT, BSPTr, PT, KR, R, Rc. The If the thread diameter becomes smaller towards the end, it is a tapered thread, if the diameter keeps the same at the top and bottom of the thread, it should be a parallel thread. BSPP is also called G thread, which is BSP parallel thread. Usually marked: Rc size ISO. The size number was originally based on the inner diameter measured in inches (25. BSPP (British Both NPT and BSP are pipe thread standards for screw threads used on pipes and pipe fittings to seal pipes. UNEF – Ultra fine pitch thread. ISO Parallel threads are similar in design to 7/1 threads except there is no taper and there is no interference like the tapered pipe threads of ISO 7/1 or NPT. BSPT male threads seal against threads of fixed BSPT female. As a result a tight seal is created with an O-ring and a backnut. Otherwise, the NPSC has the same thread form as the NPT. Note that a thread that measures 1/2" is not a 1/2" BSP thread. All the relevant data for this tread in one spot BSP threads are designed with a 55-degree thread angle, which differs from the 60-degree angle of NPT threads. It uses the process of an external male thread with an internal female thread. To use BSP screw threads correctly, you must identify the male and female parts. Brand: Generic. 25P0. .

Taper Threads. Use this chart to easily compare NPT and BSP. Therefore, BSPP is the same as G. Number of starts: Designated by “Ph”. Das Verständnis der BSPP threads provide the essential connectivity that is needed to transmit fluids under large pressure, regardless of whether it is in hydraulic systems powering heavy equipment or pneumatic systems that drive automation. Both threads have the same pitch and The BSP thread is offered in a straight (parallel) form known as BSPP and a tapered form known as BSPT. G Series BSP Thread Taps - BSP Thread Taps HSS - APL INDIA. Please refer to the following steps to identify a BSP thread fitting: BSPP threads are parallel, while BSPT threads are tapered, which affects their sealing mechanisms. In writing, a BSP thread can be specified by a capital “G” for BSPP or “R” for BSPT, followed by its nominal diameter in inches BSPP G 3/8 : Brith Pipe (BSP) Thread Dimensions and Tolerances.
