Customized special fittings are the best solution when standard fittings don't meet your requirements. We support you from the creation of the drawing to the 3.1 documentation and manufacture fittings exactly according to your specifications. These include, among other things, eccentric T-pieces for residue-free emptying, flow-optimized Y-pieces or 180° bends with outlets (point of use). In addition, connection components enable the integration of measuring and control elements to monitor temperature, flow rates or pressures. All special fittings are cleaned and securely packaged. And thus perfectly prepared for your application.
Special Fittings
We develop special fittings to meet your specific needs. Whether Y-pieces or branches with different angles – our services include everything from planning to 3.1 documentation.

When standard is not enough: Customized special fittings, perfectly optimized to your requirements
Connection components
Dockweiler connection components can be used to integrate measurement and control elements for monitoring temperature, flow rates and pressures. Whether for gases or liquids, the instrumentation T-pieces can be equipped with various sensors to measure flow and other parameters during system operation. Thanks to our manufacturing expertise, we ensure flow-optimized cross-sections and low-dead-space designs that guarantee maximum efficiency and quality.
