Rectus couplings are quick disconnect couplings designed for fast and secure connection of pneumatic and fluid lines in industrial systems. This category includes pneumatic quick couplings, safety couplings and hose couplings, featuring Parker Hannifin Rectus series such as Rectus 21, Rectus 26 and Rectus 48. Parker Rectus couplings are engineered for defined flow performance, reliable shut-off and repeated connection cycles. Typical configurations include ball-lock mechanisms, single and double shut-off designs, and male and female coupling halves with standard thread interfaces. The product family supports common pressure ranges and media used in fluid power systems. Customers receive original Parker products supported by technical expertise and global express shipping.
