What Are Hydraulic Seals and How Do They Work?

Hydraulic seals are essential components that prevent fluid leakage and maintain system pressure in hydraulic machinery. They’re commonly used in cylinders, pistons, and rods to keep oil in and contaminants out.

A reliable seal ensures longer service life, safety, and lower maintenance costs. Choosing the right seal type—rod, piston, wiper, or buffer—depends on your application’s pressure, temperature, and movement needs.

Which Hydraulic Seal Material Performs Best Under Pressure?

Choosing the right material is critical for high-pressure and high-temperature hydraulic sealing. Whether you need resistance to chemicals, extreme heat, or long-term wear, different materials like FKM, TPU, NBR, and PTFE offer unique advantages.

Learn how to select the most reliable seal material based on your cylinder design, media type, and application pressure.

Οι άνθρωποι ρωτούν επίσης

1. How to replace hydraulic cylinder seals?
To replace hydraulic cylinder seals, disassemble the cylinder, remove the old seals using a plastic pick, clean all parts thoroughly, then install new seals in the correct groove orientation. Reassemble the cylinder carefully to avoid twisting or damaging the seals.
2. How to find seal kit for hydraulic cylinder?
To find the right hydraulic cylinder seal kit, identify the cylinder’s model, dimensions, and application type. Cross-reference OEM part numbers or measure the old seals. You can also contact a seal supplier with photos and measurements for accurate matching.
3. Which seals are used with petroleum base hydraulic fluids?
Seals made from NBR (Nitrile) and FKM (Viton®) are commonly used with petroleum-based hydraulic fluids. NBR is cost-effective and oil-resistant, while FKM offers higher temperature and chemical resistance for demanding systems.
4. How to replace seals on a hydraulic cylinder?
First, release all pressure and remove the cylinder from the system. Disassemble the unit and extract worn seals with care. Clean all grooves, install new seals with proper lubrication, and reassemble the cylinder tightly to ensure leak-free performance.
5. How to measure hydraulic cylinder seals?
Measure the inner diameter (ID), outer diameter (OD), and cross-section (thickness) of each seal using a digital caliper. If seals are deformed, measure the groove directly. Always round to standard sizes and confirm material before reordering.
6. How to order hydraulic cylinder seals?
To order hydraulic cylinder seals, provide the seal size (ID, OD, width), material preference (NBR, PU, FKM), and usage conditions (pressure, fluid type). At Hengoseal, we offer fast quote support, no MOQ, and custom kits tailored to your cylinders. Contact us now to get started.
