The Unseen Heroes: Why Quality Ram Cylinder Seals Matter
Elevating Hydraulic System Reliability
In the demanding world of hydraulic systems, the efficiency and longevity of your equipment hinge significantly on the quality of its sealing components. Ram cylinders, integral to countless industrial and mobile applications, require robust and reliable seals to prevent fluid leakage, maintain pressure, and ensure smooth operation. As a leading ram cylinder seals supplier, Polypac understands that investing in superior sealing technology is not just about compliance; it's about optimizing performance and securing operational uptime. The image showcases a perfect example of such a critical component – a high-performance seal designed for rigorous conditions.Unveiling Polypac's Innovation: A Closer Look at Our Dual-Material Seal
Precision Engineering for Peak Performance
The seal featured in the image exemplifies Polypac's commitment to advanced sealing solutions. This is not just a simple O-ring; it's a meticulously engineered dual-material component. You can observe a distinct, lighter outer ring, typically made from a high-performance polymer like PTFE or a specialized thermoplastic, providing excellent wear resistance and anti-extrusion properties. Nestled within is a darker, more flexible elastomeric element, which serves as the primary sealing lip, ensuring optimal contact and fluid containment even under fluctuating pressures.This innovative combination addresses the limitations of single-material seals, offering superior performance in harsh environments where high pressures, extreme temperatures, and aggressive media are common. By leveraging the strengths of both materials, Polypac's ram cylinder seals deliver enhanced durability, reduced friction, and extended service life, making them a wise investment for any hydraulic system operator.Why Choose Polypac as Your Preferred Ram Cylinder Seals Supplier?

Question you may concern
Products
How important is surface finish on the metal parts that contact the seal?
Extremely important. A rough surface will abrade and wear out the seal quickly, causing leaks. A finish that is too smooth can prevent a lubricating film from forming. A typical recommended surface finish for dynamic applications is 0.2 to 0.8 μm (8-32 μin) Ra.
Can I reuse a seal?
We strongly recommend never reusing seals. Once compressed and used, a seal takes a "set" and its elastic properties are degraded. Reusing it almost always results in a leak. Always install a new seal during any maintenance or repair.
What is the difference between NBR and FKM materials?
NBR (Nitrile/Buna-N): A general-purpose, cost-effective material with excellent resistance to petroleum-based oils and fuels. It has a standard temperature range of -30°C to +100°C (-22°F to +212°F).
FKM (Fluoroelastomer/Viton®): A premium material with excellent resistance to high temperatures (up to 200°C+), chemicals, and oils. It is used in more severe environments but is more expensive than NBR.
When should I use a spring-energized seal instead of a standard elastomeric seal?
Consider a spring-energized seal (e.g., GSF, SPN types) for demanding applications involving:
Extreme Temperatures (below -30°C or above +200°C)
Aggressive Chemicals that elastomers can't handle
Very Low Leakage or "Zero Leakage" requirements
Poor Lubricity or dry running conditions
The internal spring maintains constant sealing force, compensating for wear and system variables.
Why did my O-ring fail prematurely?
Common causes of O-ring failure include:
Chemical Incompatibility: Swelling, softening, or cracking due to fluid exposure.
Improper Sizing: Using an incorrect size leads to over-compression or inadequate sealing force.
Abrasion: Wear and tear from rough surface finishes or contaminated fluid.
Extrusion: The seal is forced into the gap between metal parts under high pressure.
Installation Damage: Nicks, cuts, or twists during assembly.
