You should use the exact size of silicone hose for your application. Using the wrong size may cause leaks. In this article, we will show you how to measure the inner and outer diameters of silicone hoses.
How to Measure the Diameter of a Silicone Hose
To measure the diameter of a silicone hose, use a digital caliper to measure the inside diameter (ID) from the inside edge to the inside edge of the other side. If you don’t have a hose, you can measure the outer diameter (OD) of the hose connection pipe and match it with the ID of the hose. Do not use a ruler to measure, it may not provide accurate measurements.
Step-by-step guide to measuring silicone hoses
Prepare the tools you need
Prepare your measuring tools before you begin
Digital caliper – most accurate
Tape measure – For large sizes
Ruler – not very accurate
How to accurately measure the inside diameter?
Silicone hose sizes are usually measured by the inside diameter (ID)
Make sure the hose is not bent
Use a digital caliper: Place the jaws of the caliper into the hose and spread the caliper so that it touches both inner walls of the hose
Look at the measurement result: the number on the digital display is the inside diameter of the hose
Measure several times: To maintain accuracy, measure several times
How to measure the outside diameter
Use a caliper
Place the jaws of the caliper on the outside of the hose and measure the width
Use a flexible measuring tape
Wrap the measuring tape around the circumference of the pipe
Divide the circumference by π (3.1416) to get the outside diameter
How do you measure the wall thickness of a silicone hose?
Use a caliper to measure the outside diameter (OD) (ID)
Subtract ID from OD, how to divide by 2
Conclusion
Measuring the inside diameter (ID) of a silicone tube can install the correct hose. The hose obtained using a digital caliper is the most accurate. If there is no hose, the outside diameter (OD) of the pipe can be measured
