Mitutoyo Pipe and Tube Thickness Gage

Pipe and tube dial gages have a spherical anvil (ø.14") and a flat upper contact designed for measuring the thickness of a tubular wall. It can also be used by musicians to measure the graduated thickness of double reeds for oboes and bassoons. The anvil can be inserted into the tube for a distance of .78"

With the anvils closed, as shown in the photo, set the dial to zero by rotating it, if necessary. Zero setting on the digital version is as simple as pressing a button.

The lifting lever at the top is depressed with the thumb and the anvil is raised. The lower anvil is then inserted into the tube, the upper anvil is allowed to close down on the outside of the tube and a direct measurement is taken by reading the dial.

It is possible to convert the dial gage for left hand use. The indicator can be swung around 180° and the lifting lever can be moved to the other side. You can also replace the dial indicator if it ever gets damaged. You will want to order inch reading Mitutoyo indicator 2414S.

For more information on thickness measurement in general, please refer to page 12 among others.

There is no question that Amazon can offer you the best prices on almost every kind of precision measuring tool. They also offer easy no-questions-asked returns and often free shipping. The small distributor simply cannot compete. That's why we include this link so you can go directly to Amazon and see what they're offering.

Two things to consider:

  • Amazon product photos sometimes don't match the product description. It's the description that you want to pay attention to.
  • There are imitation gages on the market (specifically Mitutoyo) and you can make sure you are getting the real item by looking for the words "sold by Amazon". If it is sold by a third party, you might want to call Mitutoyo to find out if they are legitimate distributors.
