Three new HF couplings are now available, enabling the manifold to be installed completely hemp-free.
The new HF couplings allow the manifold to be connected without hemp or thread tape, supporting faster and cleaner installation. The manifold’s lower pipe can be raised for easier bottom feed and additional space inside the cabinet.
An angled ball valve is no longer required – use LK Coupling HF (angled) together with a straight ball valve.
RSK is retained for an easy transition.
Manifolds with an adjustable bracket will be introduced progressively during 2025.
