Why are Hydraulic Seals Important?

Hydraulic seals (also referred to as hydraulic cylinder seals or shaft seals) are devices designed to keep fluids from escaping from cylinders or pumps while simultaneously preventing foreign contaminants from entering them. They are vital pieces in many types of machinery since they help create a method for fluid power to be converted into linear motion (you can learn more about them here). Given the working conditions found in many of these industries, these seals need to be built to withstand high pressure. That durability is exactly what makes Allied Metrics the trusted hydraulic seal manufacturer it is today.


Durable Seals, Minimal Cylinder Repair

Hydraulic seals

As previously stated, Allied Metrics is a leader among hydraulic cylinder seal manufacturers. Our seals and other cylinder repair parts are built to last far longer than the average seal and are held in high regard by many well-known Fortune 500 companies and OEMs. And because our seals come in many different materials, dimensions and sizes (ranging from 4 mm to 1000 mm), we make hydraulic cylinder repair easy. Whether you're looking for standard sizes or need a full set of custom hydraulic seals, we have the ability to provide any shaft seal type with our cutting-edge machining services. Of course, not every machine contains both rods and pistons, so be sure you know the difference between the two, and which one is the type of seal that you need.
