Connection Sizes
½, ¾” and 1” in BSP NPT and flanged end connection.

QS Dry Disconnect coupling safety locking pin

The QS safety locking pin provides additional safety over other Dry Disconnect Coupling options. The QS Dry Disconnect safety lock pin prevents accidental disconnection.

The QS locking pin is fitted as standard on the following sizes: 1 ½” DN40; 2” DN50; 3” DN80; 4” DN100 and is also available as an option for size DN150; 6″.



Ergonomic single action operation for both the Square and Round handle QS options is designed for the rigours of repeated time pressure industrial applications and the challenges of offshore environments.
Automatic Turn and Lock mechanism ensures the connection is secure and safe.
Bump ring to guide and protect.
Selectivity system protects against cross-contamination and is fully compatible with existing systems.
5. Built-in swivel within the QS Dry Disconnect coupling removes hose twist and tension on the hose. This reduces fatigue on the hose or loading arm and means the connection process is much easier for the operator.
6. Designed and manufactured to industry standards.
7. QS Locking Pin is fitted as standard for sizes 2”, 3” and 4”. This safety feature is an additional safety benefit in demanding and fast operating conditions.
8. Completely interchangeable with other manufacturers and existing systems.
9. Automatic valve opening and closure delivers non-spill efficiency; reducing the risk of accidents and avoiding operating clean-up costs.


Industry standard and compatible with other systems
