Cam Lock Coupling SetCam & Groove Couplings, or Cam Lock Couplings, are popular in a wide array of vacuum and low pressure fluid applications where a hose assembly is frequently connected and removed. These couplings mate quickly and conveniently by inserting the grooved male adapter into the female cam coupling and simply closing the cam arms. A gasket inside the female coupling compresses as the cam arms close creating a tight leak free seal. Safety pins can be inserted to prevent the cam arms from accidental disconnection. Optional locking arms and dry-disconnect models are available to further reduce any potential spillage. Cam & Groove Couplings are available in a broad range of sizes, styles, & materials, and interchange between major brands in most sizes.

Available in Aluminum, Brass, Stainless Steel, Carbon Steel, Malleable Iron, Polypropylene, Nylon and select corrosion resistant metals (see below)
