Rod Seal Manufacturers — Polypac Hydraulic Seal Solutions
Rod Seal Manufacturers — Precision Solutions by Polypac
Polypac is one of the premier Rod seal manufacturers, offering engineered hydraulic rod seals and complementary O-rings. Founded in 2008, our custom rubber ring and O-ring factory spans over 10,000 m² (8,000 m² production space), equipped with industry-leading production and testing systems. We combine scientific R&D and hands-on manufacturing to deliver consistent, high-performance sealing solutions.
Advanced Materials & Expert Formulation
Our roots in filled PTFE—bronze, carbon, graphite, MoS₂ and glass-filled PTFE—give Polypac a material advantage. We also produce O-rings from NBR, FKM, silicone, EPDM and FFKM to meet diverse temperature, chemical and wear requirements. This deep materials expertise ensures rod seals optimized for friction, extrusion resistance and long service life.
Custom Manufacturing & Rigorous Testing
As specialized Rod seal manufacturers, we offer tailored seal design, tooling and production for special working conditions. Our factory’s advanced equipment and strict quality control protocols enable repeatable tolerances and batch traceability. We partner with universities and research institutes to validate performance under real-world pressure, speed and temperature cycles.
Applications & Performance Advantages
Polypac rod seals serve hydraulic cylinders, mobile equipment, industrial presses and subsea actuators. Benefits include low leakage, extended wear life, stable dynamic sealing, and compatibility with challenging fluids. Our engineered PTFE composites and elastomeric compounds reduce downtime and maintenance costs across heavy-duty applications.

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.
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.
What is the purpose of the metal spring in a rotary shaft seal?
The garter spring in a shaft seal (e.g., FSKR, SPGO types) provides a constant radial force on the sealing lip. This ensures consistent contact with the rotating shaft, compensating for minor wear, eccentricity, and vibration to prevent lubricant leakage.
How do I choose the right material for my sealing application?
Material selection depends on four key factors: Media: What fluid or gas will the seal contact? (e.g., petroleum oil, water, chemicals, steam) Temperature: What is the minimum and maximum operating temperature? Pressure: What is the system's operating pressure? Are there pressure spikes? Application: Is it a static, dynamic, or rotary seal? Example: NBR (Buna-N) is excellent for standard hydraulic oil, while FKM (Viton®) is needed for high temperatures or aggressive chemicals.
