High Flow Style / European Air Coupler Plug

●  The high flow or V style Air Coupler Plug has more than 2 times larger flow area than standard industrial interchange fittings. The increased flow results in greater tool efficiency and decreased air costs. The nipples are made of solid brass for better durability, and steel material is also available. Steel is hard and resilient with more damage resistance than softer metals and a wide range of working temperature, and Zinc-plated finish provides high corrosion resistance.

●  High flow air hose fittings are the male end of coupling sets, also called quick-connect air coupling plugs or nipples. They are inserted into the V style air coupler bodies (female ends) to connect pneumatic tools.

●  The high flow or V style Air Coupler Plug is interchangeable with Germany style couplings DN7.2 – 7.8, Cejn 320, Legris 25/26, Norgren 234/238, Rectus 25/26, Schrader InterCheck 35.
