Quick-connect couplings for industrial applications
Whether in mechanical and plant engineering, process engineering, or demanding industrial processes— our stainless steel quick-connect couplings offer flexible connection options for liquid and gaseous media. In addition to standard applications, suitable material and seal combinations also allow for use with chemically demanding media such as solvents, acids, and alkalis. The selection of the appropriate coupling is based on the medium as well as the respective pressure and temperature requirements.
European pressure equipment directive PED 2014/68/EU
QC Range (quick connect couplings):
All couplings are designed and manufactured according to Article 4.3 of the European Pressure Equipment Directive PED 2014/68/EU. Couplings with nominal diameters of more than 25 mm up to and including 32 mm must not be used for pumping liquid or gaseous fluids of group 1 (hazardous) according to the Pressure Equipment Directive PED 2014/68/EU. Couplings with nominal diameters of more than 32 mm may only be used for pumping group 2 (non-hazardous) liquid fluids according to the Pressure Equipment Directive PED 2014/68/EU. If used with other media, a review by Schwer Fittings should be requested.
Statement from Schwer Fittings
Description
Description of Stainless Steel Quick-Connect Couplings
Schwer Fittings' quick-connect couplings enable fast and reliable connection and disconnection of fluid-carrying lines. Manufactured from high-quality stainless steel, they are suitable for a wide range of applications in fluid technology, hydraulics, and the chemical and process industries.
Our product range includes quick-connect couplings for low- and high-pressure applications up to 300 bar, as well as various designs, connection types, and seal materials. Depending on the model, single-end shut-off, double-end shut-off, double-end open, and flat-seal coupling systems are available.
Function
Flat-seal quick-connect couplings for minimized fluid loss
Our flat-face quick-connect couplings allow for connecting and disconnecting lines with exceptionally low fluid loss. The design reduces fluid leakage during disconnection while also minimizing the risk of contaminants entering the system.
Flat-face couplings thus offer advantages in terms of cleanliness, operational safety, and handling, particularly in hydraulic applications and with sensitive process media. Depending on the model, additional locking mechanisms provide protection against accidental disconnection.
