Clip-in Plugs

The clip-in plug consists of the basic plug and the respective clip adaptor. To align the plug on the cell vent, the basic plug is able to turn on the adaptor after installation – a solution for which bfs holds the patent. The clip plug fits on bayonet cell openings (European and Asian standards) and is installed like the push-in plug without requiring a quarter turn. All parts on the inside and outside of the plug housing are fitted as form-locking components. This means that the plug can be disassembled and all its parts recycled at the end of its operating life.

Clip-in Plug – Kits IKIT

To some extent, bfs products are available as preassembled units. We deliver not only plugs with the floats installed but also complete watering systems including the hose system and water connection. However, this is only practical with plugs that can be pushed or clipped in.
