3 millimetri Air Line connettore rapido (1pc)
This is not a good product.
When you pressurise the tube, at about 50 psi the o-ring opens and the pressure is gone.
Nice item, fits tightly onto the 3mm OD pipes sold here.
weight 1.5-2 grams
length assembled 25mm
width approx 9mm
screws together with rubber seal. Haven't air tested it but it's a solid design. Refer to files tab for reference photos.
4 stars only because it may prove difficult to assemble/disassemble due to the number of turns required.
