Question: How Do You Determine Your Fitting Size?

What is the standard air hose fitting size?

Air hoses are measured by their internal diameter (ID), and come in standard sizes of ¼”, ⅜” or ½” or metric sizes of 6mm, 8mm, or 10mm.

Since higher ID correlates to higher air capacity, selecting your ideal air hose diameter requires an understanding of the CFM needs of your air tools..

What is a NPT fitting?

NPT (or National Pipe Taper) is a U.S. standard for tapered threads widely used on pipes and fittings for over 100 years. NPT connections rely on thread deformation- a metal to metal sealing design where the threads of the connectors themselves form together.

What is the ID of a 5’8 garden hose?

Most 5/8″ hoses have an outside diameter measuring between 0.77 inches and 1.00 inches.

How is pipe size measured?

Tubing is measured by the OUTSIDE DIAMETER (O.D.), specified in inches (e.g., 1.250) or fraction of an inch (eg. 1-1/4″). Pipe is usually measured by NOMINAL PIPE SIZE (NPS). … For sizes larger than 12-inch, NPS corresponds to the actual outside diameter.

How do you measure a hose fitting?

Simply run the tape measure from the top of your hose’s opening to the bottom and record its diameter. When measuring, the number should refer to the internal diameter, as this is size that needs to match the garden hose to a fitting nozzle or faucet.

What is a 3/4 NPT fitting?

A 3/4” NPT pipe thread has an outside diameter -OD – of 1.050 inches. Each thread size has a defined number of threads per inch – TPI, or pitch. The 3/4” NPT pipe thread has 14 threads per inch.

How do I know my fitting size?

To find the correct fitting size, measure the outer diameter of the threads.For a male thread, measure the outer diameter (OD) of the thread.For a female thread, measure the top diameter of the opening (OD).

How do you determine NPT fitting size?

As a general “rule of thumb” an NPT thread is approximately 1/4″ (0.25”) larger than its “name.” For a 1/4″ NPT fitting the “nominal” OD is 0.533”. NPT fittings are slightly tapered so the “nominal” diameter is the diameter in the middle of the threaded portion, as measured by the top (crest) of the threads.

What is standard hose size?

5/8 inchHose diameters range from 3/8 inch, 1/2 inch to 3/4 inch. In the United States, most standard garden hoses are 5/8 inch in diameter. The bigger the diameter, the more water is delivered.
