AL TYPE 40 (Universal purpose couplings)

Low Pressure, Single valve Type
  • Widely used and accepted couplings for air line connection.
  • Socket have automatic shut-off valve so that fluid in the socket will not run out on disconnection.
  • Important steel parts are hardened for high durability.

Note:

  • Types 40 ( 44, 46 and 48 types ) are interchangeable and types 20 are the same, but not interchangeable between 20 and 40.
  • Packing materials should be selected for the applicable fluid.

Caution:

  • Fluid should flow from socket to plug; in the opposite use, Please advise as "W TYPE".
  • Scraps of the seal tape and dust causes fluid leakage. Be careful not to stick them to the couplings.
  • Do not impact, hit, pull or bent. Don't dismantle. It causes damage to the coupling.
