Rain, snow, and humidity can cause hydraulic cylinder gland nuts to rust. Once corrosion has formed, they can become practically immovable.
This tool is different from a cylinder spanner wrench, which is unable to pack the punch of a hydraulic cylinder gland nut wrench.
A hydraulic cylinder gland wrench can loosen and tighten nuts that seal reciprocating shafts. They are adjustable and some can be customized to fit gland nuts as large as two and six-inches in diameter. An adjustable gland nut wrench can also be reversed to fit 1/4 inch to 21/64-inch pin holes.
How Much Does A Gland Nut Wrench Cost?
Adjustable nut wrenches vary in price according to their size, quality and tool name brand. Because it is a specialized tool, it is not typically accessible at local hardware stores or chains. Hydraulic cylinder wrenches can be purchased from online retailers.
Gland nut removal tools range in price from $20 to $90. The wrenches with the higher price point are generally made from better materials and are more durable.
More inexpensive wrenches do not offer a variety of size adjustment options. The lower price also means lesser craftsmanship that has gone into making the tool.

Things To Understand Before Purchasing a Gland Nut Wrench
As you may have noticed already, getting the tool which most ideally suits your needs might not be as straightforward as you thought. Some people tend to regret their purchases after trying their new gland nut wrench for the first time, while other end up as happy as possible.
If you’d like to be one of these pleased buyers, make sure to keep all of the following features in mind before making your purchase.
Size
When we talk about size, we are referring both to the size of the gland nut wrench itself and the size of the equipment that you intend to repair. Be sure that the tool has a decent enough size for you to work on your equipment.
A huge wrench doesn’t always do the deal – buy a smaller wrench if you intend to use it on not-so-large equipment.
Pins
As you might’ve noticed, these gland nut socket wrenches tend to have a lot of issues with the pin quality. In some cases, these pins come off very easily. This renders the durability of the wrench itself pretty worthless, as losing the pins turns the tool into unusable metal.
If you want to avoid unnecessary inconveniences, buy additional pins when you purchase a wrench.
Pinhole Fitting – Reversibility
Most of these tools can be reversed to fit on differently-sized pinholes. This is a big benefit offered by the vast majority of these tools, which does wonders when working with heavy equipment. All of the gland nut wrenches that we reviewed today can be reversed – if you were hunting for this feature, feel free to get the one you like the most from this list!
Durability
Imagine being in the middle of repairing a hydraulic cylinder when your wrench suddenly breaks on its own… Not so much of a pleasing scenario, right? Make sure to get a very durable and well-crafted tool from a trusted manufacturer to avoid any issues of these sorts.
Taking warranty into account
If you feel insecure about the quality of a product or its pins, you might want to take a look at those manufacturers who offer warranties. If any issue presents itself, you’ll be able to easily resolve it and the manufacturer will surely take full responsibility for it.
How To Use A Gland Nut Wrench
An adjustable gland nut wrench is only part of a tool because it doesn’t have a handle. Before use, attach the head to a ratchet handle with four-sided fastener heads. Then, identify the gland nut you will be loosening or tightening.
Adjust the wrench to fit the nut and then twist until you have achieved your desired result.
