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

Product Information

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

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 NPT - National Pipe Thread - is the US standard. Most of the rest of the world uses BSP - British Standard Pipe. The nominal size refers not to the outside of the pipe, nor even to the outside of the thread, but to its internal bore - the inside of the tube where the fluid flows. It makes sense when sizing pipes for flow rate but it makes things confusing when measuring for replacement parts. DZ or DZR symbol stamped on brass components means that the part is dezincification resistant. Dezincification is a form of corrosion that can occur within a plumbing and heating system.

Chrome Fittings

Although it is not recommended, these products can be used with other fluids but must not be corrosive or flammable. Please note, using aggressive fluids will reduce the working life of the hose or fitting.

The standard ISO 7 - Pipe threads where pressure-tight joints are made on the threads consists of the following parts:

Malleable iron fittings are perfect for a wide variety of uses. They are highly durable and very popular in the plumbing industry as they can be used in commercial and residential applications.

It is not recommended to run within the maximum pressure limits for prolonged periods of time as this can severely deteriorate the hose and fittings life span. 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.

Keeping your installation secure and tidy

Just to confuse things, often the T in BSPT refers to Thread and doesn't indicate either Taper or Parallel. In North America NPT, JIC and ORFS pipe threads are common. Some NPT threads are similar to BSPT threads so if in British Standard Pipe is the standard thread used on plumbing fittings across most of the world (but not in North America). Below, you'll find tables showing BSP sizes in mm; tables detailing the difference between BSP and the American standard NPT; an explanation of straight and tapered thread types; and a handy thread size ruler and template to print out and use at home.

G is the international standard shorthand for BSPP - BSP Parallel threads. R is the standard for BSPT - BSP Tapered. Parallel (G) threads are used where the seal is made on a mating face, like inside a cast iron radiator with the aid of a gasket. Tapered fittings achieve a tight thread-to-thread seal with the help of a little sealant such as PTFE tape or hemp and Boss White. Right first time 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. 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. NPT has flattened peaks and troughs where BSP is rounded. NPT has a thread angle of 60º where BSP is 55º. 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.

In Japan JIS tapered and parallel threads are common and are interchangable with the respective BSPT and BSPP threads, The hexagon bush collection includes stainless steel reducing bush suitable for various applications. Sizes range from 1/4” to 4”.
