“Rectus interchange” Quick Couplings
“Rectus interchange” air quick couplings refer to pneumatic quick couplers that are designed to be interchangeable with the Rectus brand couplings — a well-known European manufacturer (now part of Parker Hannifin) that established several widely used coupling profiles.
The coupling follows the same dimensions and profile as a Rectus series, so it can connect with original Rectus couplings or other brands that match the same interchange specification.
Rectus Series
There are many different pneumatic quick connector series under the Rectus brand. Including ISO international standards, European standards, etc. The ones listed here are mainly designed by Rectus. Other standards can be found from the corresponding standard page.

Other Rectus Interchange Series
Other rectus interchange series quick connectors are usually interchangeable with international standards, such as European standards, ISO6150 B standards, ISO6150-C Standard, so we will list them on other pages. Because the classification of pneumatic connectors is very complicated, we cannot list all the classifications clearly. If you encounter product interchangeability issues, you can contact us. We can help you answer questions you encounter on various quick connectors.
