Cam Lock Fittings allow for quick, secure connections of hoses to tanks or other hoses. The name "Cam Lock" comes from the Cam or Lever that is used to lock one hose or fitting into place with another one. The female connector has two cams as part of the assembly. The male connector has a shape that allows the cams to lock into place. The opposite end of a connector may have a hose barb, male pipe threads or female pipe threads. Caps and Plugs are available to seal the ends.
