System description:

Lincoln-style air couplers and nipples

           

Coupler and nipple can be joined without user pulling back on sleeve. A true quick-connect design!

Lincoln air couplers provide split-second coupling of grease guns, impact wrenches, paint sprayers and other air-operated equipment. Air flow products from Lincoln have the features and durability you demand for your business.

  • Positive locking mechanism so coupler cannot be detached accidentally.
  • Extra large air passage insures greater air flow.
  • Automatic air check valve shuts off air instantly when uncoupled, providing leak-proof seal.
  • Corrosion-resistant steel plug and stainless steel check and check spring for long service life.
  • Free swiveling action prevents curling or kinking of air hose.
