What is a G1 2 thread?

Parallel (straight) threads, British Standard Pipe

British Standard Pipe

British Standard Pipe (BSP) is a set of technical standards for screw threads that has been adopted internationally for interconnecting and sealing pipes and fittings by mating an external (male) thread with an internal (female) thread.

British Standard Pipe - Wikipedia

Parallel thread (BSPP). These are sometimes denoted by the letter G, for example G1/2" means a parallel 1/2 inch BSP thread. Taper threads, British Standard Pipe Taper thread (BSPT).

Is G thread same as NPT?

The G (BSP / BSPP) standard is used in Europe and around the world. Although the threads look incredibly similar, they are not compatible. The NPT (US Standard) thread is tapered with a 60 deg thread pitch and designed to seal when the threads compress together, with pipe tape to fill in any minor leak paths.

What does G mean on threads?

G Connections in Pressure Gauges

G connections have a straight body (constant diameter) with parallel (straight) threads. The main purpose of the parallel threads is to contain the pressure, which allows for regular installations and removals without damaging the thread.

Is G1 2 same as BSPP?

The two types of thread are the same parallel straight. BSPP is the British Standard Pipe Parallel thread and it is also denoted by the letter G (ISO standard). Therefore, BSPP is the same as G. ISO 228, DIN 259, BS2779 British Standard Pipe Parallel thread is called BSPP.

Are BSP and G threads the same?

BSPP = British Standard Pipe Parallel, cylindrical pipe thread with 55°apex angle. British parallel threads are often referred to as “G” threads, the two types of thread are the same parallel straight, the threads are measured in threads per inch. Therefore, BSPP is the same as G.

Can I use BSP with NPT?

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).

Is G1 same as BSP?

Two types of threads are used: Parallel (straight) threads, British Standard Pipe Parallel thread (BSPP). These are sometimes denoted by the letter G, for example G1/2" means a parallel 1/2 inch BSP thread.

What is G1 connection?

Inner thread connections are welded to the container with free placement according to your request. This type of connection is very reliable and provides great flexibility to connect different type of accessories while at the same time being able to close with plug later.

What is G and R thread?

These are parallel threads (BSPP), which have a constant diameter, which are known a G threads, and taper threads (BSPT), whose diameter increases or decreases along the length of the thread, known as R threads.

What is G1 4 fitting?

G1/4 is a straight thread (no tapering). This type does NOT seal in the threads, which is why you ALWAYS see G1/4 barbs with an o-ring. The o-ring provides the seal between the barb and threading. This thread type is easier to use because it provides a much more consistent seal when compared to NPT.

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 are the 3 basic types of threads?

There are three standard thread series in the Unified screw thread system that are highly important for fasteners: UNC (coarse), UNF (fine), and 8-UN (8 thread).

Are 1/2 BSP and NPT interchangeable?

NPT/NPS and BSP threads are not compatible due to the differences in their thread forms, and not just the fact that most sizes have a different pitch.

How do I know if I have BSP or 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.

Are NPT threads tapered?

NPT has a tapered male and female thread which seals with Teflon tape or jointing compound. Pipe threads used in hydraulic circuits can be divided into two types: Jointing threads are pipe threads for joints made pressure tight by sealing on the threads and are taper external and parallel or taper internal threads.

Is G thread BSPP or 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.

What is BSP female thread?

British Standard Pipe (BSP) is a set of technical standards for screw threads that has been adopted internationally for interconnecting and sealing pipes and fittings by mating an external (male) thread with an internal (female) thread.

Are BSP and BSPT interchangeable?

BSPT & BSPP Male and Female Fittings

British Standard Pipe threads are similar in function to NPT threads, but are generally not interchangeable. BSPT male threads seal against threads of fixed BSPT female.

How do you convert BSP to NPT?

BSP thread 1/2 Inch to NPT thread 1/2 Inch - threaded pipe fitting adaptor which will let you convert the BSP(UK) or G (European) thread to NPT American standard thread or other way round. You would need to just screw this adaptor into existing male thread and you will end up with other standard thread.

How do you measure 1/2 inch BSP?

Use a tape rule (or vernier gauge) to measure across the outside of the male thread. Note that a thread that measures 1/2" is not a 1/2" BSP thread. Using the table below we can see that a thread measuring 1/2" is actually a 1/4" BSP thread. Similarly, a thread that measures 1" is actually a 3/4" BSP thread.

What thread is on 15mm compression fittings?

Threads on the 8mm, 12mm and 15mm compression ends are equal to 1/4", 3/8" and 1/2" BSP in accordance with BS 2779/ISO 228. Other thread sizes are to BS 84 Whitworth.
