Let's Talk It seems to be a constant annoyance for people in the industry to accurately identify or understand tube metric fittings. If you’re new to the game, or just find Din Heavy vs Din Light too damn confusing, then have a go at Taipan’s Metric Identification resource to simplify things.
I have run a couple of simple sessions with customers and staff to really dumb things down and it seems to work. So here goes…
Metric fittings are always easy to identify if you have the male. There are two crucial measurements to take. See below.
Measurement 1: Measure across the inside diameter of the Male in the small parallel area to get your tube size. Or, if you have the tube it was attached to, simply measure the O.D. Write this measurement down.
Measurement 2: Measure the outside diameter of the thread to get the thread size. Write down this measurement, then refer to the Taipan Metric Thread Chart.
Let’s say our tube size or the inside diameter of the male measured 10mm and our thread outside diameter measured 16mm.
At this stage, you’d measure the thread pitch if you couldn’t pick it by eye. But I know you guys are already all over this part.
Start on the left-hand side of the chart down the column marked OD PITCH and find your thread size. In this case it’s 16mm. Move over to the columns marked DIN L LIGHT and DIN S HEAVY and assess which column reads 10mm for the tube size. In this case it’s DIN L LIGHT. This makes the fitting you’re trying to identify a 10mm Light fitting.
Easy peasy! If you want to be even more adventurous, you could find out how easy this is to put into a Taipan Hosetail part number.
