The world's smallest one touch fittings feature 40% smaller volume ration and 20% smaller O.D. ration in comparison to coventional type. Compact ( miniature ) one touch fittings are specially designed for pneumatic installations in equipment that are small and compact in size. Working pressure from 0~1.0Mpa (0~150psi), Working temperature from 0~60ºC (32~140ºF).

PU-C union staright compact ( miniature ) one touch fittings connect in line two tubings of equal tube ΦD, simpley push in 3mm, 4mm, 6mm, 1/8", 5/32", or 1/4" tubings on both sides.
