Diode Trading EST supplies Industrial gasket supplier orders custom-cut to any flange size or pattern, with fast delivery across the GCC. See our related PTFE Products and Rubber & Polyurethane Product ranges.
Non-Asbestos and Graphite Gasket Sheets
We supply non-asbestos gasket sheet material (aramid/NBR-bonded compressed sheet) for general industrial and process sealing, and graphite gasket sheet — flexible graphite, plain or with a tanged or perforated stainless steel insert — for high-temperature and high-pressure duties beyond what non-asbestos sheet can handle. Both are stocked in Saudi Arabia and supplied cut to your flange pattern.
Gasket Sizing to ANSI and DIN Flange Standards
Full-face and ring gaskets are cut to ANSI B16.5 (Class 150-2500, NPS 1/2″ to 24″+) and DIN/EN 1092-1 (PN6-PN40) flange dimensions on request, with the correct bolt-hole pattern, ID/OD, and thickness for your flange rating — send us the flange standard, class/PN, and size and we’ll confirm the cut sheet.
Choosing a Gasket Material
The right gasket material depends on three factors: the media being sealed (chemical compatibility), the operating temperature, and the flange pressure rating. As a general guide: non-asbestos compressed sheet suits water, steam, oil, and general chemicals up to moderate temperature and pressure; graphite suits high-temperature steam, hydrocarbons, and most aggressive chemicals; PTFE suits highly corrosive/aggressive chemicals and food/pharma applications; rubber (NBR, EPDM, Viton) suits lower-pressure water, air, and chemical service depending on grade. Tell our team your media, temperature, and pressure and we’ll recommend the right material.
Ready-Cut Gaskets to Your Drawing
Need finished gaskets rather than sheet? We cut rubber, non-asbestos, PTFE ring, PTFE envelope and rubberised cork gaskets to your drawing or flange standard — see Ready-Cut Gaskets.
