  • ISO B, Hardened plugs and sleeves along with solid bar stock construction assures long service life by providing maximum resistance to damage caused by hydraulic and mechanical shock.

  • Durable ball locking mechanism assures reliable connections every time. Many ball bearing distribute the load while providing alignment and excellent swiveling action to reduce hose torque and prolong hose life.

  • Broad range of metals and seal materials allow the use of most fluids.

  • Industry-wide interchangeability with most major manufacturers makes for the most versatile fluid system quick coupling on the market.


Series "DS" sockets incorporate valves in both socket and plug halves to prevent fluid loss when the socket is disconnected. These sockets are normally referred to as "Hydraulic Couplings", but they are used extensively with other media where appropriate. The Series "DS" sockets are available in ROHS compliant steel and brass.


Series "DS" couplings are known as "Industrial Interchange" couplings because they are dimensionally and operationally interchangeable with similar couplings of the same size manufactured by others.

Dust Plugs and Dust Caps:

BRECO offers a complete line of dust plugs and caps for their hydraulic quick couplings. When ordering the dust cap/plug, body size must correspond to that of the socket or plug.

Ordering Information:
