MEASURING AND IDENTIFYING TUBE FITTINGS

Identifying and measuring threads can sometimes be the hardest part of any fluid related project. Damaged threads or damaged fittings can often lead to misidentification and constant headaches. By using the simple steps below and by using our Universal Thread identification kit you can easily distinguish any fitting to ensure you can get the parts you need the first time.

WAYS TO INDENTIFY TUBE FITTINGS

2) Measuring the Threads and Thread Pitch

– If your female thread does not have a stamped number on it or you do not have the tube nut you will need to use a set of calipers and a thread pitch gauge to determine the proper size.

Step 2: Measure the OD of the threads

After confirming your tube size you will then measure the OD of the threads. When measuring the threads be sure to have the calipers measuring straight across the fitting versus at an angle to get the correct measurment.

After measuring all three points look onto the chart below to decide what size you fitting is. If you dont know what it is contact us and one of our trained salesman can help you get the parts you need!
