6/16" or 3/8", in AN terms the dash number is in reference to how many 1/16 of an inch the OD of the hose is. -4=1/4" -8=1/2" -12=3/4" -20= 1 1/4"
A -6AN hose has an inner diameter of 3/8 inch (approximately 9.5 mm) and an outer diameter that varies depending on the hose's construction and material. The "-6" in the AN (Army-Navy) designation refers to the size code, which corresponds to the inner diameter in 1/16 inch increments (6 times 1/16 inch equals 3/8 inch). AN fittings are commonly used in automotive and aviation applications for fluid transfer.
Internal diameter.
To accurately measure the diameter of a hose, you can use a caliper or a ruler to measure the distance across the widest part of the hose. Make sure to measure from one edge of the inner wall to the opposite edge. This will give you the diameter of the hose.
Inside diameter just like copper tubing
To accurately measure the diameter of a vacuum hose, use a caliper or ruler to measure the width of the hose opening. Make sure to measure across the widest part of the opening for an accurate measurement.
To determine the hose size based on the outer measurement, measure the outer diameter of the hose using a caliper or ruler. Then, refer to a hose size chart or consult the manufacturer's specifications to find the corresponding hose size based on the measured outer diameter.
To accurately measure hose size for a proper fit, use a tape measure to determine the diameter of the hose. Measure the inside diameter for a precise fit. Additionally, consider the material and flexibility of the hose to ensure it will meet your needs.
I assume you want to find out how much water fits in the hose. Treat the hose as a cylinder - that should be a good approximation, even when you bend it. Measure the length and the interior diameter. Divide the diameter by 2 to get the radius. Convert everything to feet, and finally use the formula for a cylinder to get the volume.
The inner diameter of a shop vac hose is typically around 1-1/4 inches, while the outer diameter is usually around 1-1/2 inches.
The diameter of the lower radiator is 1 1/2 inches on the radiator side, the water pump diameter is 1 3/4 inches. The hose has 2 different size ends.
To accurately measure the size of a shop vac hose, use a measuring tape or ruler to determine the diameter of the hose. Measure across the opening of the hose to find the diameter in inches or millimeters. This measurement will help you identify the correct size for replacement or accessories.
The shop vac hose size for this model is 1.25 inches in diameter.
