Double nipples & Screw fittings

We offer double nipples in various qualities. Regardless whether brass, nickel-plated brass, stainless steel, plastic or galvanised steel, all form a combination of two external threads. They serve for adapting various threads and thread types. For example, it is possible with the double nipples to reduce from a large thread to a small thread or for example to adapt from a metric thread to an imperial one. In order to position the components after assembly, we recommend the use of separable double nipples or also pipe screw connections (flat or conical sealing). Practical tip: Often an exotic adapter can be built with the metric and imperial threads of a cutting ring fitting.
