Seal Repair kit

Cypher SPRSEALS - it starts with seals

Since 1998, in the field of mechanical seal work and control, we have made step-by-step efforts to overcome the limitations and difficulties of the factors that affect the stability of the sealing performance, such as the material and the shape of the sealing lip.
Since 2000, continuous improvement and optimization of polyurethane elastomer materials and research on mixing with different materials and chemical raw materials. While the physical properties are balanced, new material performances after different chemical mixtures are also deeply developed.

Regarding the mixing research and development of nitrile rubber, hydrogenated nitrile rubber, silicone rubber, fluorinated rubber and various metal powders, countless deployment tests have also successfully realized the ideal special sealing material.
In the development and improvement of polyamide (nylon resin), polytetrafluoroethylene, and phenolic resin, we also ushered in a rapid increase in the number of our European customers and a doubled increase in sales in the Asian market.

We are researching dust seals (DKBI), piston rod seals (IDI, IUH, HBY), support rings (KZT,), piston seals (OUH, SPGO) in conventional hydraulic sealing systems day after day ), anti-wear rings/anti-wear rings (WR, SPGW) and are suitable for all kinds of jib cylinders, cantilever cylinders, bucket cylinders, lifting cylinders, and power steering cylinders.
Including the research and development and iterative production of the sealing ring of the hydraulic breaker, there have also been more new breakthroughs.

Thank you very much for your attention. If you have any demand for sealing system solutions, please be sure to contact me. I will cooperate with you in an honest and professional manner.
