Many people are unsure how to get the correct custom clamp measurement needed to order and purchase a custom clamp for their radiator hose. There are three main ways in which you can measure to get an accurate number, these include using a cloth measuring tape, a six inch scale with a slide caliper, or a dial caliper. Let’s break it down so you know how to measure accurately using each of these systems and what number(s) you’ll want to send us.
This is a very simple and easy to use measuring tool. All you need to do is simply take your cloth measuring tape and wrap it around the diameter of the radiator hose. The number that we are looking for is where the cloth tapes come together. For example: if your measurement reads 6 ⅞”, this is the number around the diameter that you will send to us. Once we have this measurement we then divide that number by pi (3.14), this number will give us the diameter of your hose clamp, which we will then machine and send to you.
When using a scale with a slide caliper you will need to send us two different measurements. We recommend measuring over the spring clamp on the particular hose you’re measuring for (do not remove the spring clamp). The number on your caliper you get from measuring across the spring clamp and the thickness of the spring clamp, are the numbers you need to send us in order to create a proper fitting custom clamp.
This method is prefered in order to get the most accurate measurement. You can purchase a dial caliper at your local Harbor Freight for about ten dollars or here. Just like with the slide caliper, open your car and take the clamp measurement around the banded clamp on your radiator hose. The number that your dial caliper shows, is the number you send to us.
In some situations, it may be difficult to get your calipers to measure around the spring clamp or band. In this instance, we’ll have you measure a different way with the calipers. With the hose pushed onto the inlet of either the water pump, the radiator, or the thermostat, you’ll need to take two measurements. Remember to use a soft touch for measuring, measure vertically and horizontally on the hose, the two numbers you get are the clamp measurements we need sent to us. Make sure to let us know that you didn’t measure across any type of clamp, just over the rubber while it was in place.
If the measurements you send us are off by a little bit, it isn’t the end of the world. When we send you your custom clamps you will also receive three compliment liners to offset any inaccurate measurements, even if they are an ⅛ of an inch off.
