Specifications

Start with the interface. Then check the exact variant, dimensions and application.

General
MaterialStainless steel 304 as standard; 316 available on request
The bulkhead union is constructed with a stainless steel body and a push-in mechanism that secures the tube without tools. The half thread version has a shorter threaded section, while the full thread version provides a longer thread for thicker panels. Both versions are used to route tubing through enclosures, cabinets, or machine frames, maintaining a seal and strain relief. Installation involves inserting the fitting through a panel hole and securing it with a locknut (not included unless specified). The push-in connection allows for quick assembly and disassembly of tubing. Typical applications include pneumatic control panels, instrumentation, and fluid handling systems. When requesting a quote, specify: tube size (e.g., 4-4 mm), panel thread (e.g., M12x1), thread type (half or full), material (stainless steel), quantity, and packaging requirements. Additional parameters such as operating pressure and temperature are not provided here; please state your requirements for confirmation.
