Looking for a Rectus® 20 Series compatible quick release coupling or plug?
This guide explains the recommended Kee Connections replacement, compatibility considerations and the available product configurations.
What is the Rectus 20 Series?
The Rectus 20 Series is a compact quick release coupling profile commonly used for compressed air and pneumatic applications where a small connection size and reliable performance are required. It has been widely specified by OEMs and maintenance teams across industrial equipment, automation systems and general workshop installations.
When replacing existing couplings, many users look for a compatible alternative that allows them to maintain or repair equipment without redesigning the complete pneumatic system. Selecting the correct replacement requires the connection profile, valve configuration and application to be considered together.
