Find the right Product in the STEINCONNECTOR Product Search!

The STEINCONNECTOR Product Search offers powerful filtering features that allow you to quickly and easily find the right quick-release couplings, plugs, and accessories for your requirements.

You can filter the following attributes in our product search:

• Applications: Filter couplings, plugs, and accessories by industry or application area, such as "Breathing Protection," "Fluidics," "Medical Technology," "Water, Wastewater, and Waste Disposal Technology," and many other fields.

• Connection Type: Choose between external threads, internal threads, or hose connections, depending on your needs.

• Main Material: Find the appropriate material for your application, e.g., brass, steel, or stainless steel.

• Series: If you already have a specific series in mind, you can search for it directly.

• Variant: Filter by different variants, such as break-away couplings, venting couplings, manual locking with a locking nut, or automatic locking with a special plug.

• Key: If coding is required, you can filter by key types such as hexagon, octagon, tri-point, round, etc.

• Nominal Size: Filter by the nominal size of the coupling to find the exact right product.

• Coupling/Plug: Choose whether you need a coupling or a plug.

• Seal: Depending on the application, a specific seal may be required – choose from materials such as EPDM, Perbunan, Viton, FFKM, and others.

• Valve: Decide whether the coupling should be drip-free, bi-directionally sealing, uni-directionally sealing, or valve-free.
