In addition to some 500 gasket profi les, EMKA has introduced a range of pre-assembled gasket rings and frames which, with fully-sealed ends and corners, remove the chance of manual trimming errors. Sealing of ends and corners is essential to maintaining full sealing performance of a gasket profi le, eliminating problems of ‘cutting short’, which leaves a gap in the installed gasket strip. This also addressess the problem of sealing into a square corner – often achieved by running the gasket around and creasing the material or by cutting and not adequately sealing.

Pre-assembled gaskets are ideal for rapid application to door frames or apertures such as skylights, vents, access panels in electrical/electronic cabinets or enclosures. Standard shapes include butt joins and right-angle joins, enabling rings and frames. Assembly is very simple by pushing or knocking onto a fl ange.
