About this deal

They are often referred to as metric connections because they are used in the metric system and the dimensions are based on metric measurements.

BSP Male DIN16288 and G1/4 Male EN837 are a couple of examples of how this style of connection is described.They are both the same, since the ’19’ refers to 19 threads per inch (tpi) which is the standard thread pitch for a 1/4 BSP P thread. Due to the spiral leak path, however, Teflon® tape (PTFE) or a sealing compound is required to create a good seal. If the pressure is not going to exceed 16 bar we would suggest a John Guest PM010612E 6MM x 1/4″ straight threaded to tube adapter fitting. 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.

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. 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. No need to use a hex key for installation, just tighten it to the external thread, and install it directly on the top of the isolation valve.To avoid the problem of awkward gauge positioning, use a “crush washer” and hand-tighten the connection. Not knowing the exact application and set-up it is almost impossible for us to diagnose the issue from a distance.

As for the “A” or “B” in some name, such as the common G ¼ B connection type, the letter denote lets users know 1) it’s a male thread, as female BSP threads don’t have a final letter, and 2) its tolerance class. The connector is made of nickel-plated brass, so you can be sure of long-lasting service without any risk of rust or corrosion. Often the 2nd P is left off because BSPT tapered threads are less common and BSP is assumed to be parallel unless otherwise specified. The pressure experts at WIKA USA understand national and international measurement standards, pressure gauges, and which ones are best suited for your industrial processes.Choose this straight adaptor from RS PRO for leak-free and stable connections for your pneumatic system. Some pressure connections also include a tapered shank which assists in the correct alignment of the bonded seal.

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.This adapter will convert holes which fit size 1/2" BSPP male threads to a female 1/2" NPT threaded hub. This brass straight screw in connection is designed with male threads and a compression ring fitting connection.
