G Thread (Metric BSPP) Female to NPT Thread Male Pipe Fitting Adapter - Lead-Free (Two 3/4 inch)

Product Information

In the USA, NPT (National Pipe Tapered) is the most popular process connection, especially in businesses of oil and petroleum. Compared with BSP, NPT is easier to cut and user-friendly, and is considered a booster to American Industrial Revolution. Being a kind of screw thread system, NPT is tapered thread with the pressure tight seal being made on the thread itself. The most common sizes are 1/4, or 1/2 inch NPT. 1/2"NPT MALE The adapter has a built-in O ring seal which acts the same as bonded or dowty seal for sealing the 1/4 BSP (G1/4) thread end.

The “M” designation for metric screws indicates the nominal outer diameter of the screw, in millimeters (e.g., an M6 screw has a nominal outer diameter of 6 millimeters). (Source from Wikipedia) ISO 262 selected sizes for screws, bolts and nuts A common variation of this Process Connections is the M/F-250, or the autoclave fitting. This fitting has a cone at the end of it for pressure ranges above 10,000 psi. It is also commonly referred to as a Sno Trik® fitting as well – though that is a brand name. BSP sizes don't match up with what you measure on the scale of a ruler, which can obviously cause some confusion. For example a 1/2 inch BSP thread (see above) actually measures more like 3/4 inch with a ruler. International Standards Organization Specification 228/1, straight threads, reference specification: BSPP, DIN 259, JIS B0202. The BSPP is excellent at the high pressures seen in hydraulics. It's often used in North American hydraulics, too.BSPP is the standard for hydronic radiators in the UK, Europe & Asia. Most of the flat panel ones & towel warmers sold in The sealing technique for both types is fundamentally different, NPT relies on the gradual compression of the flanks of the internal and external thread to directly form a seal on the thread, whereas a G1/4 provides the mechanism for compressing a seal typically between two flat surfaces at one end of the male thread. Adapt G1/4 (1/4BSP) female to accept 6mm OD tubing There are two distinct styles of seal typically used for pressure instrumentation with a BSP thread fitting. BSP is a technical standard called "British Standard Pipe". It covers two distinctly different threads: Most of the time, the answer depends on geography. In the U.S. or Canada, the pressure gauge will most likely come with an NPT (National Pipe Tapered) connection. This thread type, standardized by ANSI (American National Standards Institute) and ASME (American Society of Mechanical Engineers), is typical among North American measuring instruments, found in piping systems, pumps, compressors, plumbing systems, mobile working machines, and many more applications.

When placed side by side, the difference between the two connection types is clear. The NPT thread is slightly tapered, while the G connection is straight. Another obvious visual: The G connector ends with a small protrusion (nipple), used to center the gasket. If calipers are handy, a third method is to measure the angle between threads: NPT threads are 60°, while BSP threads are 55°.

NPT Connections in Pressure Gauges

The 6mm OD tube is simply pushed into the other end of the adapter and it self-seals with the tube. To remove just lift the inner part of the adapter to break the seal and release the tube. Inch BSP - Central heating oil line connectors, some European toilet cistern fill valves (not common in UK). DIN3852-A is used with a bonded seal (also known as a Dowty seal) which is a steel washer that has an elastomer ring bonded to the inside diameter of the washer. Some pressure connections also include a tapered shank which assists in the correct alignment of the bonded seal. If there is no tapering it is advisable to use self-centering bonded seals to avoid a poor alignment of the seal which may compromise pressure tightness.

Inch BSP - Bathroom basin taps and kitchen sink taps, radiator connections, shower hoses, old outside tap outlets, toilet cistern fill / float valves. BSP Male DIN16288 and G1/4 Male EN837 are a couple of examples of how this style of connection is described. Prefixing with G, is equivalent to adding BSP after the pipe size, although BSPP is more strictly correct to define the parallel version. external) & 3B (internal): for applications where closeness of fit and/or accuracy of thread elements are important. Where can we source a pressure DP transmitter flanged with a flush diaphragm for liquid level measurement with an output over 0-200 inH2O?

Please note:

I have a pressure sensor for use on air with a G1/4 female process connection and would like to convert it so it can accept 6mm OD tubing. Would you have some kind of adapter that could do this?
