Flange Aligner Buyers Guide – What To Look for When Buying Flange Aligners

The Flange Wizard Brand

As you may have noticed, all of our recommendations come from the same brand – Flange Wizard. Flange Wizard is well known for their superior quality products. They have been in business for over 35 years and they are well-known within the industry. In our search, we were able to find some promising brands, but we felt that none of them could quite stack up to the Flange Wizard brand. As far as quality goes, it is hard to find products that can compare to what they create consistently. That is why we have a strong preference towards the Flange Wizard brand.

Two-Hole Flange Aligners

Two hole flange aligners are designed to allow you to align a pipe up horizontally with the ground using two of the holes. It will help you ensure that the pipes are aligned correctly and it will save you valuable time making adjustments. It has been shown to decrease fit uptime by over 50% and it completely removes the frustrations that come with attempting to balance a level using pins on your own. It is a must-have tool for anyone that works on aligning and fitting pipes together.

Flange aligners are inserted into two holes in the flange. From there, you will use a series of levels, which vary depending on the type of aligner you are using, to align the type parallel to the ground. You can use both the horizontal and vertical levels to align the pipe perfectly in a matter of minutes.

Two-Hole Alignment

The two-hole alignment is necessary in order to create two pivot points on the pipe. While the two hole flange aligner will be able to work with any two holes as long as the cross pin is long enough, the simplest way to use it is to insert the aligners into to neighboring holes. This makes aligning the flange as easy as possible.

Magnetic Centering Head

A magnetic center heads is a tool that is used to mark the exact center of a pipe or a curved metal object. They come in two different sizes which are suited for either small/medium or medium/large size pipes. The feet of the centering head rest securely on the pipe and stabilize it in place. The magnetic forces hold it in place so that it doesn’t move. This allows you to get an exact measurement without any interference.

They come equipped with a degree dial in the center which encases a bubble level inside of it. The level can be adjusted at small increments at a time. These interments will usually range between 2° to 3° each. In most case, 3° adjustments will do just fine. If you need more precise measurements, you should look for centering heads that allow for 1° or 2° adjustments.

By turning the center dial, you will be able to adjust the positioning of the level. The dial can be turned 360° so that you can use it anywhere around the pipe. This type of adjustment is necessary if you want to use the centering head at all positions around the pipe.

The magnetic feet of the centering heads allow you to position them on the pipe and trust that they will not move. It frees up your hands for more accurate and safe marking. The magnet is strong enough to attach the centering head completely upside down if needed.

You can find centering heads that are not magnetized, however, we recommend sticking to the magnetized variety because of how easy they are to use.

Each centering head has a nail that aligns vertically through it. Once it is positioned correctly, you can create your marking by tapping down on the center nail using a hammer. These nails are built to last, but they can be replaced they start to wear down.

Small and Standard Center Heads

Small magnetic center heads are designed for pipes that range from 1 inch to 10 inches in total diameter. The feet of the centering head are closer together which allows it to fit on the smaller diameters of these pipes. They are ideal for contractors that regularly work with small pipes such as fence builders, fire service and protection contractors, and those that work with building corrals and pens for livestock. They also have a variety of uses in the automotive industry as well.

The standard magnetic centering head is designed for larger pipes. These pipes will typically range between 8 inches and up to 4 feet in diameter. If you look at them, you will quickly notice that the feet on each side of the centering head are much wider. This is to allow it to sit securely on larger pipes. They are ideal for welders that regularly work on larger pipes or tanks.


The price you should expect to pay will vary based on what you are looking for specifically. If you are simply looking for a two-piece flange aligner and only the basics, the cost is lower. If you are looking for something more, like the flange wizard kit that we reviewed above, you should prepare yourself to pay more.

The choice will ultimately depend on your needs. If you have specific needs that fall outside of the products that we have featured here, you may have to spend a little more.
