Polypac Custom Piston Seals
Polypac Custom Piston Seals
Polypac custom piston seals provide dependable sealing for hydraulic cylinders in demanding environments. Backed by a 10,000+ m² facility and advanced production equipment, our seals combine proven materials and precise manufacturing to reduce leakage, friction, and downtime.
Why choose Polypac piston seals?
- Tailored designs for your application — size, profile, and material customized to fit performance needs.
- Wide material range — filled PTFE variants and diverse elastomers for temperature, wear, and chemical resistance.
- Consistent quality — rigorous testing ensures long service life and stable performance under pressure.
- Fast prototyping and production — efficient processes for quick delivery and scalable volume.
Materials & custom options
We started with filled PTFE and now offer bronze-, carbon-, graphite-, MoS₂-, and glass-filled PTFE for low friction and excellent wear resistance. For elastomeric seals, choose NBR, FKM, silicone, EPDM, or High Quality FFKM to match temperature, oil compatibility, and seal flexibility. Polypac engineers help select the right combination for long-term reliability.
