New HF couplings – install without hemp and thread tape

Three new HF couplings are now available, enabling the manifold to be installed completely hemp-free.

LK-Coupling-HF-hemp-free-connection-manifold

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.

LK Coupling HF

LK Coupling HF is intended for hemp-free installation to the LK Manifold RF. The coupling is available in both angled and straight versions. When combined, the couplings are dimensionally adapted to fit the hole pattern in LK’s installation cabinets. The coupling's swivel nut comes with a pre-mounted gasket, and the external thread of the straight coupling is sealed with an O-ring. If needed, complement with LK Nipple HF for a hemp-free connection to LK Ball Valve Straight G25 / LK Optiflow EVO II.
