Does the company supply O-section (or some other suitable) gasket extrusion for forming a vacuum seal between a rectangular frame-supported membrane and a flat surface?

Hi Rod,

We don't sell anything, however, the EPDM draught-excluder seals that are available from most hardware stores are perfect, these have been used in many industrial vacuum press applications for years, they're self adhesive, hold a perfect vacuum and are cheap! here's a link to the sort of thing that I mean, i'm sure you'll be able to track some down locally.
