Hydraulic Glands
Hydraulic glands are critical to maintaining proper sealing, rod support, and overall hydraulic cylinder performance. PSI Hydraulics supplies OEM replacement and aftermarket hydraulic glands for a wide range of industrial and mobile applications, with reverse engineering and custom manufacturing available when replacement components cannot be sourced.

Overview
Hydraulic glands, also known as rod glands or cylinder heads, secure the sealing system at the rod end of a hydraulic cylinder while supporting the piston rod throughout its operating stroke. They house rod seals, wipers, bearings, and other sealing components that help prevent hydraulic fluid leakage, minimize contamination, and maintain proper cylinder alignment.
Because hydraulic glands experience constant contact with moving components, wear can eventually affect seal performance, rod support, and overall cylinder reliability. Replacing a worn or damaged gland during a hydraulic cylinder repair can help restore sealing performance and extend the service life of the cylinder.
PSI Hydraulics supplies OEM replacement and aftermarket hydraulic glands for a wide variety of hydraulic cylinders used throughout construction, oil and gas, manufacturing, agriculture, marine, mining, and material handling industries. When replacement glands are unavailable or no longer manufactured, our team can reverse engineer existing components and produce custom replacements that match the original fit and function.
Whether you need a standard replacement gland or a solution for an obsolete hydraulic cylinder, PSI Hydraulics provides the technical expertise and manufacturing capabilities to help keep your equipment operating reliably.

Why Choose PSI
Finding the correct hydraulic gland involves more than matching basic dimensions. Seal configurations, thread specifications, bearing locations, and mounting features all influence how the gland performs within the cylinder assembly. PSI Hydraulics helps customers identify and source replacement hydraulic glands for a wide range of equipment while providing reverse engineering and custom manufacturing when replacement parts are unavailable. By combining hydraulic product knowledge with precision machining capabilities, we help customers minimize downtime and restore hydraulic cylinders with confidence.

Frequently Asked Questions
How can I identify the correct hydraulic gland for my cylinder?
Hydraulic glands are identified by several critical features, including rod diameter, bore dimensions, thread style, seal configuration, bearing design, and mounting method. If this information is unavailable, PSI Hydraulics can evaluate an existing gland or cylinder assembly to help determine the correct replacement.
When should a hydraulic gland be replaced during a cylinder repair?
Hydraulic glands should be inspected whenever a cylinder is disassembled. Excessive wear in the bearing surfaces, damaged threads, worn seal grooves, or corrosion can compromise sealing performance and accelerate wear on other cylinder components. Replacing a worn gland during a rebuild can help prevent repeat repairs.
What happens if an OEM hydraulic gland is no longer available?
If an OEM replacement gland has been discontinued or cannot be sourced, PSI Hydraulics can reverse engineer the existing component and manufacture a replacement that matches the original dimensions, sealing features, and mounting characteristics.
Why is seal groove accuracy important in a hydraulic gland?
Seal grooves must be machined to precise dimensions to properly retain seals and maintain the correct amount of compression during operation. Improper groove geometry can contribute to fluid leakage, premature seal wear, increased friction, and reduced hydraulic cylinder performance.
