What does BSP stand for on a tap?
British Standard Pipe
BSP is the abbreviation for British Standard Pipe. The thread, as defined by the ISO 228 standard, uses Whitworth standard threads, and is among a number of technical standards for screw threads that has been adopted internationally for interconnecting and sealing pipes and fittings.
Is 1 BSP the same as NPT?
NPT and BSP threads are not interchangeable due to the differences in thread forms. NPT threads are pointed in the peaks and valleys, where BSPs are rounded. Most notably, the NPT thread angle is 60 degrees versus the BSP 55-degree angle.
What are BSP thread sizes?
What are BSP thread sizes?
BSP Size | Also Known As | Actual Diameter (Metric) |
---|---|---|
1/8″ | 9mm | |
1/4″ | 12mm | |
3/8″ | 15mm | |
1/2″ | 15 BSP | 19mm |
What is BSP thread used for?
British Standard Pipe (BSP) is the title of the set of technical standards that identifies specific screw threads. Countries all around the world have adopted these standards and put them to use for interconnecting and sealing pipes and fittings.
How do you identify BSP threads?
Once you have the thread size, you then need to determine the number of threads per inch to verify that it is a BSP fitting. You can do this by counting the number of thread crests over a 1/4″ length and then multiply this by 4 to get the number of threads per inch.
Is BSP straight thread?
BSP Thread Type – British Standard Pipe You’ll find it used all throughout Europe. There are two types of BSP threads, BSPP and BSPT. BSPP refers to parallel or straight threads. Meanwhile, BSPT refers to tapered threads.
Can you fit NPT to BSP?
NPT and BSP threads are generally not compatible due to the differences in their thread forms. NPT threads have a 60° included angle and have flattened peaks and valleys (this is a Sellers thread form); BSP threads have a 55° included angle and have rounded peaks and valleys (this is a Whitworth thread form).
Which is better NPT or BSP?
It will depend on whether you’re using something manufactured in the US or Canada, when you should use NPT fittings, or elsewhere in the world, when you should most likely be using BSP fittings. Is NPT or BSP better? Neither system is better than the other and both have been in use for over a century.
How do I know my BSP thread size?
To find the thread size:
- 1) Measure the O.D (outer diameter) of the BSP thread.
- 2) Take the O.D measurement (in inches) and subtract 1/4 inch (. 25”).
- 1) Multiply 3.5 by 4 to get 14. This is the number of threads per inch.
- 2) Combine the thread size with the number of threads per inch and refer to.
Is 1/2 inch BSP the same as 15mm?
Whilst most 15mm compression fittings are 1/2″ bsp, (some earlier ones had finer threads) the same cannot be said for 10mm and 8mm.
What is the difference between BSP and BSPT?
BSPP is also called G thread, which is BSP parallel thread. To form a seal or connection by 60 cone or washer or O-ring on the boss. And BSPT is a taper thread, it creates a seal by thread. Both Threads have the same pitch and angle 55 degree.
Is BSP and BSPP the same?
BSP stands for British Standard Pipe technical standards. BSP connection includes two types of threads, one is BSPP which can be straight or parallel; the other one is BSPT, which is tapered. The thread pitch and thread angle is the same 55 degree. BSP is not the same as BSPP.
