Global Leader – Breakaway Coupling and Emergency Release Systems

KLAW is a global leader in the manufacture and supply of Breakaway Coupling and Emergency Release Systems; products used in the safe transfer of hazardous and non-hazardous liquids, gases and powders.


Applications include Ship-to-Ship, Ship-to-Shore. Ship-to-Rig, Road Tankers and Rail cars.

KLAW products protect loading and unloading systems from costly damage due to spills.  This significantly reduces the risk of downtime, damage to assets, injury to personnel and harm to the environment.


KLAW has been designing, manufacturing and supplying breakaway solutions since 1980 and now has over 10,000 units in service throughout the world.

The oil, gas and petrochemical industries has long trusted KLAW to deliver products that ensure protection and peace of mind.

In August 2006 KLAW was involved in the first commercial Ship-to-Ship transfer of LNG. A project that is typical of KLAW innovation, experience and technical ability.

No Partial Break with a KLAW Flip-Flap

KLAW is the only source for the original Flip-Flap design which not only provides minimal headloss but also eliminates the risk of a potentially hazardous Partial Break event.

Partial Break is when a breakaway coupling has been partially separated. This could occur where an operator begins to move a vehicle, then realizing that they have not disconnected and then stopping. With alternative designs of breakaway coupling it could be possible for the potentially hazardous “Partial Break” to occur thus leading to an uncontrollable spillage.

The KLAW Flip-Flap design ensures that before the seal between the two coupling body halves open to the atmosphere, the internal flap valves have been released to provide 100% shut-off.

Safety by design

KLAW manufactures to the highest standards.

Every coupling is made to exact specifications based on factors such as hose strength, flow rate, working temperature, working pressure and media type.

Where necessary all products are manufactured in compliance with the PED (Pressure Equipment Directive 97/23/EC) verified by TUV® (Ident. 2529) and ATEX Directive (94/9/EC)
