Zero Leakage Seal — Reliable, Long-lasting Sealing Solution

Polypac Zero Leakage Seal is engineered to stop leaks before they start. Designed for hydraulic cylinders, oil systems and equipment in harsh environments, these seals combine proven materials and precise manufacturing to deliver dependable performance and extended service life. Backed by Polypac’s 15+ years of sealing expertise, they reduce downtime and maintenance costs.

Why Choose Polypac Zero Leakage Seal?

- Exceptional leak prevention: Advanced designs and material blends ensure a tight seal under high pressure, temperature swings, and contamination.

- Custom solutions: From standard O-rings to complex rubber rings and filled PTFE seals, we tailor seals to your operating conditions.

- Quality you can trust: Our 10,000+ m² facility and industry-leading equipment support consistent production and strict testing standards.

- Research-driven innovation: Long-term collaborations with universities and research institutes keep our products at the cutting edge.

Materials & Manufacturing

Polypac produces seals from a broad range of materials to match specific needs: filled PTFE (bronze, carbon, graphite, MoS₂, glass), NBR, FKM, silicone, EPDM, and FFKM. Our filled PTFE expertise ensures low friction and excellent wear resistance, while elastomers offer flexibility and chemical resistance. Every seal is manufactured and tested with precise equipment for consistent quality.

Typical Applications

Zero Leakage Seals are ideal for hydraulic cylinders, pumps, valves, compressors, and industrial machinery in construction, agriculture, oil & gas, and manufacturing. They perform reliably in extreme temperatures, high pressure, and contaminated or abrasive environments.

Benefits at a Glance

Longer service life, fewer leaks, lower maintenance costs, and tailored designs to fit special working conditions. Polypac’s rapid prototyping and custom production shorten lead times and get your equipment running sooner.

Q&A

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.
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 a static seal and a dynamic seal?
A Static Seal is used between two surfaces that do not move relative to each other (e.g., pipe flanges, end caps). O-rings and gaskets are common static seals. A Dynamic Seal is used between surfaces that do move (e.g., piston and cylinder, rotating shaft). Rod seals, piston seals, and rotary shaft seals are designed for this purpose.
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.
