Gaskets & Gasket Sheets

Compressed fibre, PTFE and graphite gasket sheets are cut into flange gaskets for pipelines, pumps, valves and vessels. Seven Star LLC, an independent supplier in Muscat, supplies gasket sheet materials from Klinger and Garlock to maintenance teams and fabricators in Oman and the GCC.

Types of gasket sheet in this category

Fibre-reinforced NBR sheets such as KLINGERSIL C-4300, C-4400, C-4430, C-4324 and C-4500 and Garlock BLUE-GARD Style 3000 and 3200 cover water, steam, oils and gases at moderate temperatures. Klinger Quantum uses HNBR for higher temperature service and top-graph 2000 adds graphite. Filled PTFE sheets like Klinger top-chem 2000, 2003, 2005 and 2006 and Garlock GYLON Style 3500, 3504, 3510, 3530, 3545, 3565 and EPIX handle aggressive acids, alkalis and solvents.

How to select a gasket sheet

Choose the material on the fluid, temperature and pressure, then check its P x T limit for the gasket thickness you intend to use. PTFE grades suit chemicals but need correct bolt load to avoid creep, fibre sheets suit general utilities, and graphite-containing sheets suit higher temperatures. Specify the sheet thickness and size, or the flange standard and size if you need cut gaskets.
