KEC Quick Release Couplings works on a simple push & pull principle. The Adaptor when pushed into the coupler is securely help by the self-locking arrangement resulting in a positive and leak proof connection. This action simultaneously opens the valve and the fluid flow starts. To disconnect, pull back the sleeve of the coupler, the adaptor ejects out and valve shuts off automatically.


KEC Quick Release Couplings are manufactured from the selected raw materials under strict quality control.

Technical Description

The FF coupling system has double shut-off, dry break and single-handed operation. During uncoupling there is no oil loss, and during coupling there is no inclusion of air into the system.


Dry break quick connect coupling. With minimum pressure drop. Single-handed operation. No oil loss during uncoupling. A safety-closing ring prevents unintentional disconnection. Also available with pressure Eliminator, i.e. coupling is possible up to a back pressure of 400 Bar.


For the use under extreme conditions in the chemical industries, building machinery and in all industries.

Cam Lock Couplings

Design Principle

The principle behind the design of the Cam lock is simple pivot pins for coupler cam arms which lock into the adaptor groove are located so that when the line pressure attempts to force the cam lock apart, the bottom edge of the adaptor groove pushes with equal pressure against the under edge of the cam arm increasing the locking action. When properly connected, line pressure will not separate a cam lock with recommended pressure limit.


Cam locks are manufactured from selected raw materials under strict quality control.
