Double nipples & screw connections

We offer double nipples in different qualities. Regardless of whether it is brass, nickel-plated brass, stainless steel, plastic or galvanized steel, they all form a combination of two external threads. They are used to adapt different threads and thread types. With the double nipples it is possible, for example, to reduce from a large thread to a small thread or, for example, to adapt from a metric thread to an inch thread. In order to position the components after assembly, we recommend using separable double nipples or pipe fittings (flat or conical sealing). Practical tip: You can often build an exotic adapter using the metric and imperial threads of a cutting ring screw connection.
