Hydraulic cylinder covers in three material options

Durable, High
Strength Materials

Protect Hydraulic Cylinders in Any Work Environment.

Specifically designed to fit your machine, we custom build each patented Seal Saver using durable, lightweight and flexible material that covers the entire cylinder when fully extended. Our materials protect cylinder rods from dirt ingressions, abrasions, dings and dents and are a practical choice for everyday applications, while extending the life of cylinders up to three times longer.

From hot slag to salt water, every industry has its own challenges protecting equipment in harsh environments. Specifically constructed for your application, we have a range of Seal Saver protective boot material options to choose from, each with its own advantage.

Product Description

Kevlar fiber is a lightweight fabric woven—face down—in a 3/1 left hand twill pattern. The fabric is coated on both sides with medium gray silicone rubber and is resistant to some chemicals and acids. It protects hydraulic equipment that is exposed to high heat and harsh environments, making it a good application in rock quarries or demolition sites where a stronger, denser fabric is needed.

NOTE: Our Kevlar fabric has passed FAA's one hour "Igloo Fire Test", which may allow certain narrow body combi airplane operators to comply with the FAA's new air worthiness directive #AD-93-07-15.

Ballistic Nylon

Product Description
Ballistic Nylon is woven from nylon yarns of various denier (weight). The double weave 1050 denier fabric is the most durable for its weight level. It's sturdy, yet flexible nylon is resistant to abrasions, water, oil, sunlight and tearing and is backed with polyurethane (which aids in waterproofing). The material will not break down with age and can be used continuously in temperatures up to 250 °F, making it ideal for protecting hydraulic cylinders in most working environments.
