I will also need this piece if possible It is a straight through connector in preferably nylon, with 3 mm through hole. Taper screw at one end and push fit with barbs at the other end It is for 4 mm ID tube The wings are just to make it easy to screw the taper thread into tube. 联系方式Co:Vulcan Sun Ltd Add:United Kingdom Tel:44-121-4408078 Email:rob@vulcansun.com Website:http://www.vulcansun.com
