Cam & Groove Spool Reducing Couplings

Special camlock couplings are made to connect pipes, hoses, threaded fittings and equipment in more specialized situations. 

Reducing couplings enable varying diameter pipes to be connected without the use of multiple threaded connections. Reducer Coupling can be an adaptor or a coupler paired with a male thread, a female thread or a hose shank of different size. One piece body makes it stronger. 

Shyang-Twu, a Taiwan QRC coupling manufacturer, offers spool reducing couplings available from Type A to Type F in SS316, Bronze, and PP materials.

Sizes ¾inch x ½inch, 1½inch x 1¼inch, 1inch x 1¼inch, etc. Follow the links for more details.
