Rectus Ranges

Rectus quick couplers are used in many industries, mainly for connecting hoses and modules quickly and leak free.

They are often used for fluid and gas connections. Depending on the design, the connecting elements for low pressure are suitable for a pressure of up to 35 bar.

The quick couplings are available in the most common materials such as brass, steel, stainless steel, PVDF, and are also increasingly used in plate or block applications.
