About this deal

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. The push-in fitting comes with a sealing ring on one side and threads on the other side, so it's quick and easy to connect and doesn't require any special tools. Tightening, though, has to be done with care: Too much compression can lead to galling, and over-tightening can damage the threads.

They are often referred to as metric connections because they are used in the metric system and the dimensions are based on metric measurements. These are sometimes denoted by the letter G, for example G 1/2" means a parallel 1/2 inch BSP thread. The problem is the length of the process connection is 23mm as per PT drawing and the female fittings have maximum depth of approx.

Some pressure connections also include a tapered shank which assists in the correct alignment of the bonded seal. While it is possible to mix and match NPT and BSP in most applications if the right amount of dope is used, I would tend not to recommend it. Inch BSP - Central heating oil line connectors, some European toilet cistern fill valves (not common in UK). Another obvious visual: The G connector ends with a small protrusion (nipple), used to center the gasket.

The other common style of sealing a BSP thread is to make the seal around the outside of the thread at the opposite end of the thread via an elastomer seal sandwiched between the two outer surfaces that come together. Once the connector bottoms out to make the seal, the positioning of the instrument cannot be changed. The inner diameter of connector: 25mm(/G3/4inch), outer diameter: 20mm(G1/2inch), overall length: 34mm/1.The only difference between the two thread forms is that the A form has a slightly tighter thread tolerance than the B form. The size was originally based on the inside diameter, measured in inches, of a steel pipe for which the thread was intended. Caution: The screw connection must not be used with hot water, drinking water or in the food sector. Due to the spiral leak path, however, Teflon® tape (PTFE) or a sealing compound is required to create a good seal. Prefixing with G, is equivalent to adding BSP after the pipe size, although BSPP is more strictly correct to define the parallel version.
