Non-Locking Couplings, 316 Series

Parker Stratoflex offers a range of non-locking coupling designs, materials, features, and sizes for fluid system applications. Non-locking couplings are commonly used in aerospace and military fluid cooling systems, providing modularity for key components such as electronics boxes and fast, reliable connection to open-fluid flow when the coupling halves are fully engaged.
The 316 series non-locking couplings are equivalent to size -3 (316 inch) for fluid flow area. They are uniquely designed to connect with self-aligning valving for applications needing inlet and outlet fluid flow.
Locking the coupling halves in place typically requires some form of external retention and latch. The 316 series couplings are often used in electronic boxes or cards that install into an overall rack or chassis that provides the cooling fluid. These couplings make the connection between the rack-coupling half and the module- (or box-) coupling half to allow fluid flow when fully engaged. Self-aligning valving allows for manufacturing tolerances to be accommodated and the coupling halves to align properly during connection.
Self-sealing valving prevents fluid spillage and leakage when the coupling halves are disconnected. Parker uses our precision valving design, common in many of Stratoflex coupling products, to provide optimum fluid-flow characteristics.
