A complete reference to Kastas sealing technologies; rod seals, piston seals, wipers, guide rings and static seals for hydraulic and pneumatic applications.
Kastas has been active in industrial sealing for more than 40 years: product design, development of elastomer and polymer materials, and the production line, all under one roof.
Kastas products are used in hydraulic and pneumatic sealing and in the fluid power industry, and are available through the company's global sales network. Besides standard sealing elements, part of the Kastas team also works on custom solutions for specific industries.
This catalog is a reference to Kastas sealing codes: hydraulic rod and piston seals, wipers, guide rings, static seals and pneumatic types, together with the material, maximum pressure, working temperature and permitted speed of each code.

The Kastas booth at an international sealing industry exhibition.

The Kastas R&D team works on the next generation of sealing: product and tooling design, new materials, and testing them before they enter mass production.
The Kastas production line, from raw material to finished product, works toward zero defects, and the company's in-house test center checks every stage before shipment.

Kastas has a sales headquarters and authorized agencies in Turkey, a European company named Kastas Europe GmbH in Germany, and active distributors in 81 other countries.
The main distribution center in Izmir, covering 4,200 square meters, stocks more than 30,000 unique products and processes more than 2,000 orders a day, exporting to 81 countries.
Material, maximum pressure, working temperature and allowed speed for each code, grouped by packing type.
