EURO-Profile couplings

Series 510, 520, 530, 540, 550, 560 and 570

Our EURO-profile couplings are produced in strong and impact-resistant quality materials. Because of an optimized valve system the couplings have a low drop of pressure. The couplings are pressed together to prevent leaks and have an easy connecting and disconnecting – so easy that it can be done with one hand.

The EURO-profile series are adjusted different purposes:
Series 510: Low connection force. Suitable as vacuum couplings.
Series 520: For heavy-duty use. Low weight.
Series 530: For heavy-duty use.
Series 540: Made of stainless steel 316.
Series 550: Made of stainless steel 316. Ball cage and valve are made of POM.
Series 560: Suitable as vacuum couplings.
Series 570: Low connection force. Safety coupling with a 2-step release system.

The couplings have the following compatibility:
Standard: EURO
Flow diameter: 7,8 mm
Connectable with the following:
Cejn 320, Hansen Auto Flo 24, Proquix 1420 og 1421, Legris 94xx A, Oetiker SC Series C, Prevost ESC 07/ERC 07, Rectus-Tema 25, 26 og 1600.

The JWL couplings and nipples with external thread can also be delivered with teflon.
