The High Flow Air Coupler provides more than 2 times larger flow area than standard industrial interchange fittings. It helps you quickly switch between different air tools and accessories. It is a must have air fittings for pneumatic tools, air compressors, air blow guns and air hoses etc, and widely used in light engineering environments. This range of couplings is lightweight and compact design, which has proved popular in the robotics, medical, instrumentation and automation industries.. The high flow style, or European style / V style, interchanges with a common high flow European couplings: 1/4 body size interchange with DN7.2 – 7.8, CEJN 320, Rectus 25; 3/8 body size interchange with DN10, Rectus 27 and CEJN 410. Both steel and brass material are available. The solid brass construction provides high corrosion resistance and prolong service span. Protective shoulder helps to avoid dirt penetration. Integral sleeve guard resists accidental disconnection. Recommended to use Teflon tape.
