Threaded restrictors

For simple and space-efficient flow restriction, we offer threaded restrictors in sizes ranging from 0.3 to 4 mm, with thread dimensions from M5 to M12. A threaded restrictor is a compact insert that is installed directly into a threaded port in a hydraulic system to restrict fluid flow. With its fixed orifice, it functions as an effective flow restrictor—completely without moving parts. This makes it a reliable and maintenance-free solution for adjusting flow rates without the need for separate valves.

Individual plugs

We offer a wide selection of individual threaded restrictors from EIS Inserts & Systems, made from high-quality stainless steel. They are available in a variety of sizes to suit different applications.

Assortment kits

For greater flexibility, we also provide convenient assortment kits containing a selection of different orifice sizes. If you have specific flow requirements or preferences, we’re happy to assemble a customized kit tailored to your needs.
