Once the connector bottoms out to make the seal, the positioning of the instrument cannot be changed. Some pressure connections also include a tapered shank which assists in the correct alignment of the bonded seal.

Choose this straight adaptor from RS PRO for leak-free and stable connections for your pneumatic system. You can change your choices at any time by visiting Cookie preferences, as described in the Cookie notice. This is the source of the confusion, as people incorrectly think the size refers to the outside diameter of the male thread. We don’t share your credit card details with third-party sellers, and we don’t sell your information to others. They are often referred to as metric connections because they are used in the metric system and the dimensions are based on metric measurements.To assist you with any product related question we created a request form which enables you to contact us in the most convenient way. We suggest you contact Wika or ABB, which are both instrumentation manufacturers that specialize in the supply of differential pressure transmitters with oil filled diaphragm seals and capillary tubing. Have you ever looked at a pressure gauge in a pipe assembly and wondered which connection type it has? Im trying to put a pressure gauge on a 55 gallon drum ,i put pressure in the tank but not one pressure gauge will work ,i put the gauge on the top of the tank ,right on the lid , and it wont give me the pressure . I would like to know if a 1/2 inch NPT instrument connection would fit into a 1/2 inch BSP sample port or could we use a G 1/2 B connection instead?

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.Tightening, though, has to be done with care: Too much compression can lead to galling, and over-tightening can damage the threads. This brass straight screw in connection is designed with male threads and a compression ring fitting connection. Just to confuse things further, often the T in BSPT refers to Thread and doesn't indicate either Taper or Parallel. The tapered shape of the NPT threads allows users to continue turning the connection several more degrees after making the seal – until the instrument reaches the desired position.

The pressure experts at WIKA USA understand national and international measurement standards, pressure gauges, and which ones are best suited for your industrial processes. Neither will work, BSP or G parallel threads are not compatible with NPT tapered threads, ideally you should use an adapter between the two threads to be sure of a reliable seal between the two different types of thread.There are mainly two ways of identifying a british standard pipe parallel (BSP-P) thread, either with the thread size suffixed by “BSP-P” or prefixed with “G”. Since finishing my business apprenticeship with WIKA Germany in 1985, I have worked in many different positions and areas. Not knowing the exact application and set-up it is almost impossible for us to diagnose the issue from a distance.

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 inner diameter of connector: 25mm(/G3/4inch), outer diameter: 20mm(G1/2inch), overall length: 34mm/1. 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. Universal fitting with internal thread CELLFAST IDEAL G1 / 2 "- G3 / 4", for water intake with external thread. Compared with other same products in the market, this shower hose joint has thicker interface, explosion-proof and pressure-resistant, more durable, suitable for Grohe tap, ballfix valve, the adapter can be applied for 13mm EU taps and 15mm UK faucet, and with the rubber washer make more sealed and leak-proof. Male (external) NPT connections are somewhat conical, with the diameter of the threads decreasing slightly from socket to tip.
