The Polywedge barrel seal is used to secure tension rings on barrels and drums.
The barrel seal Polywedge is a wedge-shaped, flat body. This is inserted into a narrow, elongated sealing opening on the closure of a closed clamping ring that is attached to a barrel or drum. There it is wedged in such a way that it cannot be removed without a tool. The Polywedge is suitable for sealing openings with a width of 15.0 to 16.5mm and a depth of 3.0 to 3.5mm.
The Polywedge seal is delivered without a label.
