Regarding the fittings, there is one more detail you need to know. Almost all of the fittings nowadays use the G1/4“ thread (12.9mm wide) and this is the industry standard for all mainstream custom loop liquid cooling manufacturers.

What is G pipe fitting?
Parallel (straight) threads, British Standard Pipe Parallel thread (BSPP; originally also known as British Standard Pipe Fitting thread/BSPF and British Standard Pipe Mechanical thread/BSPM), which have a constant diameter; denoted by the letter G.
What is G thread?
G (supposedly from German/English “Gas”) are the cylindrical pipe threads used on originally inch based pipes. The internal (conical) pipe thread is is described as “GCon”. The size designation (like 3/8″) does not mean actual thread OD; it is the internal diameter of the pipe, on which it is used.Are NPT and G threads compatible?

What is the difference between G1 4 and 1/4 NPT?
G1/4″ is a straight thread, and why PC fittings come with O-rings. NPT is a tapered thread that is self-sealing, but usually needs something like plumber’s tape for a good seal.
Is G thread parallel or tapered?
If you have any questions please contact us or check out our fittings with BSPP/ BSPT (G) thread. Female and male thread are both parallel. Female thread is parallel and male thread is tapered. Female thread can also be tapered: Rc, but this is not common.Is G thread a BSP?
Is G thread the 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.
Is G thread the same as R thread?BSP distinguishes between two types of threads. 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.
Article first time published onIs 3/4 BSP the same as 22mm?
If your ball valve is 22mm it is a copper compression fitting otherwise all screw threads in the UK even on 22mm metric fittings have 3/4 BSP threads.
Are NPT and BSP 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.
What is UNF and UNC thread?
The Unified Thread Series is classified into coarse threads, fine threads and extra fine threads much like Metric screw threads are. UNC: Is the symbol for Unified coarse pitch threads. UNF: Is the symbol for Unified fine pitch threads. UNEF: Is the symbol for United extra fine pitch threads.
What does NPT and G mean?
NPT threads are common in the United States and a few other countries, BSP threads (also know as the R subset according to ISO 7) are widely used in many other countries. BSPT -British Standard Pipe Taper. BSPP -British Standard Pipe Parallel (G) NPT -National Pipe Taper. NPS -National Pipe Straight.
What does NPT stand for in threads?
The best known and most widely used connection where the pipe thread provides both the mechanical joint and the hydraulic seal is the American National Pipe Tapered Thread, or NPT. NPT has a tapered male and female thread which seals with Teflon tape or jointing compound.
Is gas thread same as BSP?
This type of thread is also known as BSP parallel thread (cylindrical) or “Gas” thread (G). The cylindrical thread to ISO 228-1 is a type of Whitworth thread, a name derived from the inventor of it and whose origins date back to England in the mid-nineteenth century.
What is G1 process connection?
G1-1/4. This process connection is also sometimes referred to as an Ingold fitting. It uses a female threaded union nut to mate with a fixed socket welded to the bioreactor vessel. The seal between the sensor holder and the socket is created with the O-ring on the sensor body.
Is SAE and UNF the same?
There are two general types of SAE bolts (sometimes referred to as machine screws). UNF (fine thread pitch) has more threads per inch than the same diameter bolt in the UNC (coarse thread pitch). Nut dimensions are maximums per SAE. … All dimensions are in inches.
How do you read thread sizes?
Thread sizes are given in nominal sizes, not in the actual measurement. The exact measurement is slightly below the named or nominal size. For example, a 6mm bolt may measure 5.8mm or 5.9mm, but it is called 6mm bolt. It is also common to use “M” before the bolt size, such as M6 for a 6mm bolt.
Are NPT and IPT threads compatible?
IPT (Iron Pipe Thread) is equivalent to NPT; Some sources also refer to IPS (Iron Pipe Straight); using IPS risk confusion with NPS listed below.
What is BSP measurement?

What is a PG thread?
The PG stands for Panzer-Gewinde . This is a German type thread. The Main difference on this vs NPT and Metric is that the depth of the thread is smaller but has a larger flank angle, which makes it have a wider pitch along with a straight thread.
What is the difference between UNC and NPT?
UNC is Unified Coarse thread , the successor to the obsolete National Coarse (NC) thread. … NPT National pipe thread is used (in the U.S.) for plumbing of water and gas pipes, and threaded electrical conduit. NPT is defined by ANSI/ASME standard B1. 20.1, American National Standard Taper Pipe Thread.
What does MIP and FIP mean?
MPT stands for Male Pipe Thread and MIP stands for Male Iron Pipe which both indicate a male fitting with NPT threads. FPT stands for Female Pipe Threads and FIP stands for Female Iron Pipe which both indicate a female fitting with NPT threads.
Is RC thread same as Bspt?
BSPP is parallel thread, BSPT, R and Rc are taper thread, but Rc is female BSPT thread. BSPP and BSPT (in most cases) have different threads per inch (TPI) (and consequently the pitch).
Is 3/4 BSP the same as 20mm?
For threads and PVC Pipe: half inch refers to 15mm, three quarter inch refers to 20mm, one inch refers to 25mm, one and a quarter inch refers to 32mm, one and a half inch refers to 40mm, two inch refers to 50mm. … A standard 15mm garden tap has a 15mm BSP Male threaded inlet and 20mm BSP Male threaded outlet.
What thread is on a 22mm compression fitting?
The threads on compression fittings are usually 1/2″ BSP and 3/4″ BSP (for the 15mm and 22mm fittings).
How do you measure plumbing fittings UK?
- 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.
Will BSP fit Bspt?
The BSPT (tapered) male will mate with a BSPT (tapered) female, or a BSPP (parallel) female. … The BSPT connector is similar to, but not interchangeable with, the NPTF connector. The thread pitch is different in most cases, the thread angle is 55° instead of the 60° angle found on NPTF threads.
Can you thread NPT to BSPP?
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 the full form of BSW thread?
The principal features of the British Standard Whitworth (BSW) thread form are that the angle between the thread flanks is 55 degrees and the thread has radii at both the roots and the crests of the thread.
