How do you measure tubing fittings?

Answered by Arthur Reyes

When it comes to measuring tubing fittings, there are a few steps you can follow to ensure accurate measurements. The first thing you'll need is a piece of string or flexible measuring tape. This will help you determine the circumference of the fitting, which in turn will allow you to calculate the diameter.

To begin, wrap the string around the pipe or fitting, making sure to go around the widest part. If the fitting has male threads, wrap the string around the threads themselves. It's important to wrap the string snugly, but not too tight, as this could distort the measurement.

Once you have wrapped the string around the fitting, mark the point where it touches itself. This will give you a reference point to measure from. Carefully remove the string from the fitting and lay it flat on a surface. Using a ruler or measuring tape, measure the distance from the end of the string to the marked point. This measurement represents the circumference of the fitting.

Now, to calculate the diameter, you'll need to divide the circumference by pi (π), which is approximately 3.14159. This will give you the diameter in units of length. If you prefer to work with fractions, you may need to convert the decimal measurement to a fraction.

For example, let's say the measured circumference is 10 inches. Dividing this by pi gives us a diameter of approximately 3.1831 inches. If we prefer to work with fractions, we can convert this to 3 3/16 inches.

It's important to note that when measuring tubing fittings, precision is key. Even slight variations in the measurement can result in a poor fit or leakage. Therefore, it's always a good idea to double-check your measurements and ensure they are as accurate as possible.

In my experience as a sommelier and brewer, I have come across various types of tubing fittings, each requiring careful measurement. Whether it's a siphon tube or a keg connector, accurate measurements are crucial in order to achieve the desired results. I have learned through trial and error that taking the time to properly measure fittings can save a lot of frustration in the long run.

To summarize, measuring tubing fittings involves wrapping a string around the fitting, marking the point of contact, and calculating the circumference. From there, dividing the circumference by pi will give you the diameter. Remember to be precise in your measurements and consider converting decimal measurements to fractions if necessary.
