If you need to connect a run of metal or hard plastic tubing, using a pp compression fitting is a versatile and common solution that’s tried, true, and trusted. Since pp compression fittings have the ability to withstand high pressure and extreme temperatures, ensuring that you select the right pp compression fitting is critical for a safe, tight, and secure fit. And determining the exact fitting size to use is easy. Here are a couple of steps to follow to select the right compression fitting.

How to Measure a Threaded PP Fitting

To measure a threaded pp fitting, measure the thread diameter at the widest point across the threads. For a non-threaded pp fitting, measure the actual insert opening diameter or tube being inserted into the compression sleeve.

Next, compare your pipe measurements to the chart below to determine your correct size pp compression fitting. When the compression fitting has been sized, you’ll need to take into consideration whether any additional piping can be done to make a straight connection or if a directional fitting is needed.

The compression connector family is ideal when working with any rigid tubing, including tubing from fluoropolymers (PFA, PTFE, PEP, PVDF), from other rigid plastics (nylon, polypropylene, polyethylene), and from metals. Compression fittings can also be used with flexible tubing; that will require a tubing insert made from a rigid material that helps the tubing maintain its shape.

So, by following a couple simple steps and working with the table provided, selecting the correct pp compression fitting for the application at hand is as easy as one, two, done! Pair your fittings with the proper metal or plastic tubing and cut that tubing to size with one of our handy tube cutters.
