Flangeless Plugs | Silicone Rubber Bakewell Firtrees





BAKEWELL FIRTREE Flangeless PLUGS are temperature resistant silicone rubber hollow tapered plugs, with annular rings along its taper. These assist the plug to fit into holes that need masking or protecting.

Flangeless Plugs, also called BAKEWELL® FIRTREES, feature a handgrip on the top to assist in insertion and subsequent removal.

Identical flangeless plugs made from EPDM and neoprene rubbers are also available where extremes of temperature aren’t present.

The Flangeless Plugs are used to mask holes, both plain and threaded, during finishing operations such as electro-static powder coating, E-Coat, wet painting, plating and anodising. They are also useful for temporary plugging up of pipes and hoses to prevent ingress of dirt.

Like other BAKEWELL silicone rubber parts in our ranges, the Flangeless plugs are colour coded by size, for easy identification and selection.
