CEJN manufactures QC couplings for the semicon industry


CEJN is an independent family owned business with its roots in Sweden since its start in 1955 which manufactures reliable and specially designed quick connect couplings for the semiconductor industry, ensuring no spill at disconnection eliminating the risks of contamination in sensitive environments.

CEJN is committed to high quality products with focus on performance, safety and environment, secured through own development and production in a spirit of continuous improvements of processes, technologies and products.


  • ultraFLOW SC Quick Couplings
    ultraFLOW SC Quick Couplings - Available in DN5, DN10, DN12 with threaded or double ferrule fittings

  • ultraFLOW SC Quick Couplings with double ferrule tube fitting can be used with any type of fluid and are primarily intended for liquid cooling solutions within the semiconductor manufacturing industry. The ultraFLOW has extremely good pressure drop performance that will benefit the overall system performance. The flat-face design will guarantee no spill on connection or disconnection also in a system under pressure. This allows for hot swaps to avoid critical system downtime. As it is made of stainless steel, it can be used in corrosive environments and with any type of fluid, even deionized water, glycol mixtures, mineral or synthetic oils or dielectric fluids. The couplings are also suitable for two-phase liquid cooling solutions as they have shown equally good performance for both liquids and gas. The low pressure drop of the ultraFLOW will help improve the systems energy efficiency as the total pressure drop of each coupling, hose, pipe and component adds up and is highly affecting the total energy efficiency of the cooling system.
