Cup Forms

Cup seals and cup arcs are available with and without brush holders, or can be installed with mounting tabs. Click here for available mounting tabs. Channel sizes include A, B, C, D, F, G, and K and are available in galvanized and stainless steels. Standard minimum cup outside diameter (OD) and standard minimum arc outside radius (OR) depends on channel size and channel material as shown below. (For cup and arc forms with K channel, contact your Sealeze Sales Representative for maximum and minimum radii). A wide range of synthetic, natural and metal filaments are available.

Ez-Flex Strip Brush is available as an alternative to metal back brush. It's great for use around curves and in-field installation. Click here for more information.

If your application requires a cup form with diameter and radius less than those shown, contact a Sealeze Sales Representative for more information.
