Frequently Asked Questions (FAQs)

1. What thread are air tools?

If the thread size is 3/8” on your air tool then a 3/8” body fitting is what you need. If you are operating a large air tool it may have ¼ or 3/8 inch thread to screw your male plug into.

2. What are the different type of air fittings?

There are many different types of air fittings but most air tools use one of just a few types of connector. The main things to consider are the fitting type and the thread size. Common fixing types include ¼” BSP, ¼” PCL and 3/8” NPT.

3. What size are air hose fittings?

Thread sizes are typically 1/8", 1/4", 3/8", 1/2" or 3/4" pipe thread. A fitting that has female pipe threads (FPT) can only mate to something with male pipe threads (MPT) that are of the same pipe thread size. Nominal - the inner diameter size that the compressed air passes through.
