Push-in Plugs

The push-in plug S35 is a compact unit that simply pushes in. All parts on the inside and the outside of the plug housing are fitted as form-locking components. Using no glued or welded connections was a conscious decision. It means that the plug can be disassembled and all its parts recycled at the end of its operating life.

Push-in plug IV with float housing A4N540/580/620/660/700

The push-in plug for all lead-acid batteries with a vent size of 35 mm (S35) and fixed mounting depth.
The robust housing encircles the float completely in that way to protect the filling system against a malfunction, because of encreasing of the seperators. The design of the housing ensures as usual the checking of acid density through the service hole on top of the plug.
