1/2" BSP Thread Pipe Connection Elbow Male x Female Screwed Fittings

Product Information

At least 41 thread sizes have been defined, ranging from 1⁄ 16 to 18, although of these only 15 are included in ISO 7 and 24 in ISO 228. [3] [4] [5] [6] The size number was originally based on the inner diameter (measured in inches) of a steel tube for which the thread was intended, but contemporary pipes tend to use thinner walls to save material, and thus have an inner diameter larger than this nominal size. In the modern standard metric version, it is simply a size number, where listed diameter size is the major outer diameter of the external thread. For a taper thread, it is the diameter at the "gauge length" (plus/minus one thread pitch) from the small end of the thread. The taper is 1:16, meaning that for each 16 units of measurement increase in the distance from the end, the diameter increases by 1 unit of measurement. Please use a suitable tool to fasten and remove the fittings through the outer hexagon or inner hexagon of the fitting body. When tightening the fittings threads, please refer to the recommended torque amount listed in the recommended torque values information above. If the torque amount exceeds the recommended value, it can cause stress to the threads and may cause the fitting to break, or the gasket to deform and cause the fitting to leak. BES has all the steel fittings you need, from screwed stainless steel elbows to hose tail adaptors. Some of the most popular product types within this range would include: Parallel (straight) threads, British Standard Pipe Parallel thread ( BSPP; originally also known as [1] British Standard Pipe Fitting thread/ BSPF and British Standard Pipe Mechanical thread/ BSPM), which have a constant diameter; denoted by the letter G.

Taper threads, British Standard Pipe Taper thread ( BSPT), whose diameter increases or decreases along the length of the thread; denoted by the letter R. Parallel (straight) threads, British Standard Pipe Parallel thread (BSPP). These are sometimes denoted by the letter G, for example G 1/2" means a parallel 1/2 inch BSP thread.Making BES your one-stop shop for all your steel pipe fittings needs is a no brainer. Our range includes all the essentials possibly needed as well as specialised fittings.

The threads are rounded equally at crests and roots by circular arcs ending tangentially with the flanks where r ≈ 0.1373 P All Metric fittings are not supplied with any sealing equipment and require the use of PTFE/Teflon tape when being installed.

Screwed brass fittings in all sizes

We are often asked why malleable iron fittings are so popular. Malleable iron fittings are heavier than standard pipe fittings; they have good thermal expansion and vibration damping properties and do not break during assembly. Malleable iron fittings at your door in no time One of the most commonly used pipe fittings, stainless steel tees are used to adjust the flow rate and change direction. Our steel tees come in sizes ranging from 1/8” to 4”. The right steel fittings for your needs They have been designed to join piping systems by coupling thread ended pipes and accessories available as male thread and female thread connector types and a selection of thread standards to choose from e.g.: BSP, NPT or G. Threaded joints are mainly used on smaller diameters pipes in non-critical applications such as domestic oil, gas, air conditioning, heating ventilation installations but can also be seen in pneumatic, automotive applications. Common types of threaded fittings are 90° elbows, 45° elbows, tees, straight fittings, square head plugs, hex head plugs, reducers, adaptors, flanges, caps, bushings. Threaded fittings systems ensure leak-tight connections in all low-pressure, low-temperature installations where vibration is not encountered. What does DZ on brass fittings mean? In Europe Metric (DIN) pipe threads are common on German machines. These generally have a 1.5mm thread pitch, although The hexagon bush collection includes stainless steel reducing bush suitable for various applications. Sizes range from 1/4” to 4”.

Please note that it is only recommended to use these products with air or pure water (pure water must not exceed 60°C). In pure water applications, if the temperature of the fluid exceeds 60°C, the heat and moisture can cause damage to the fitting's body and gasket. At certain sizes, NPT and BSP share the same number of threads per inch - at ½" and ¾" - but at all other sizes the two are quite different. The table below lists the TPI for both NPT and BSP at sizes commonly used with domestic radiators. Nominal Just to confuse things, often the T in BSPT refers to Thread and doesn't indicate either Taper or Parallel.NPT has flattened peaks and troughs where BSP is rounded. NPT has a thread angle of 60º where BSP is 55º.
