What are BSP sizes?
Although BSP is a foreign thread, it isn’t actually metric. This is why it comes in imperial sizes: 1/8, 1/4, 1/2, 3/4, and so on. BSP parallel threads commonly seal via a 30° chamfer on the male thread to a 30° recessed cone inside the female thread (swivel only).
How is BSP measured?
How to Measure Your BSP Fittings
- Measure the outer diameter (OD) of the thread (in inches)
- Then subtract 25% from this (¼ inch)
- You’ll then need to make sure it is a BSP fitting so by counting the threads on your coupling, perhaps only just over ¼”, you can just multiply this by four to find the threads per inch.
What is the diameter of 1 BSP?
What are BSP thread sizes?
| BSP Size | Actual Diameter (Imperial) | Actual Diameter (Metric) |
|---|---|---|
| 1″ | 1 & 1/4 inch | 31mm |
| 1 & 1/4″ | 1 & 2/3 inch | 40mm |
| 1 & 1/2″ | 1 & 3/4 inch | 45mm |
| 2″ | 2 & 1/4 inch | 57mm |
Is BSP and NPT the same?
Both NPT and BSP are pipe thread standards for screw threads used on pipes and pipe fittings to seal pipes. Both threads have the same pitch and the familiar shaped peaks and valleys. In BSP, they are rounded. Secondly, the NPT angle of the thread is 60 degrees and the BSP angle is 55 degrees.
Does NPT fit BSP?
NPT and BSP threads are generally not compatible due to the differences in their thread forms. NPT and BSP thread pitches (threads per inch, TPI) are listed below. You can use 1/2″ and 3/4″ NPT and BSP fittings together, but all others will be incompatible and will therefore leak.
What is 13mm in BSP?
What is BSP thread size?
| BSPP Size | Male Thread Outside Diameter | Female Thread Inside Diameter |
|---|---|---|
| ¼” | 13mm/0.51” | 11.9mm/0.47” |
| 3/8” | 16.5mm/0.65” | 15.2mm/0.60” |
| ½” | 20.8mm/0.82” | 19.1mm/0.75” |
| 5/8” | 22.8mm/0.90” | 20.8mm/0.82” |
Is there a metric pipe thread?
Pipe Threads. These metric pipe thread sizes have been adopted by the ISO (International Standards Organization), and are primarily intended for pipes or tubes for screwing together or into ISO pipe ports on valves, cylinders, pumps, and other components.
Are 1/2 BSP and NPT interchangeable?
NPT stands for National Pipe Taper and common in the USA and BSP stands for British Standard Pipe and are used widely around the world. You can use 1/2″ and 3/4″ NPT and BSP fittings together, but all others will be incompatible and will therefore leak.
What is BSPP and BSPT?
BSP includes BSPP & BSPT thread. 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.
