Stecko Type Couplings

Stecko type couplings produced by Darmet Sp. z o.o. are used to connect hoses in hydraulic equipment used in the mining industry.

We manufacture a wide range of connectors with diameters DN6, DN10, DN12, DN19, DN25, DN31,DN38 oraz DN51. All hydraulic fittings are made on modern CNC machines. We have three CNC lathes with bar feeder and four CNC vertical machining centers. With modern CNC machinery and well qualified staff we guarantee high quality of our products. We offer also short delivery time.

The entire range of hydraulic fittings includes:

All offered hydraulic adapters have certificate KOMAG Institute of Mining Technology in Gliwice.This certificate allows for the use of our connectors in underground coal mines and salt.

Couplings with diameter DN6, 10, 12, 19, 25 and 31 are carried out in accordance with the Polish Standard PN-G-32000: 2011. However connectors with a nominal diameter DN38 and DN51 are produced in accordance with DIN 20043:2003-09.

Complete connector consists of the female adapter and male adapter with back up washer, sealing o-ring and the U-shaped staple.

All manufactured fittings are protected against corrosion by the 8?m zinc coating.
