Knowing how to order PTFE sheets and rods saves time and avoids costly mistakes. PTFE (Teflon) is sold in many thicknesses, diameters and grades, and a wrong choice means a part that wears, leaks or chemically attacks too early. This guide explains the standard sizes, the grades and the details to send when you request a quote.
The goal is a clear specification on the first message, so that we can quote from stock in Dammam and ship to your site anywhere in Saudi Arabia.

PTFE sheets are available from 3 mm to 100 mm thick, in sizes such as 300 x 300 mm, 1000 x 1000 mm and up to 1000 x 2000 mm. PTFE rods are available in diameters from 16 mm to 100 mm, with a standard length of 1 metre and cut lengths on request. PTFE tubes are available with outside diameters from 19 mm to 600 mm.
Custom parts are also possible: gaskets and machined components can be cut to your flange or drawing dimensions.
Virgin PTFE (100 percent) is the pure grade, used for electrical insulation, food processing and pharmaceutical applications. Glass-filled PTFE (15 percent) adds strength and wear resistance. Graphite-filled PTFE (15 percent) reduces friction and handles heat well. Read our graphite filled PTFE guide and the full PTFE grades guide to compare.
Thin sheets are used for gaskets, liners and seals, while thick sheets are machined into bearings, slide plates and wear parts. Small rods are turned into bushes and seats, and large rods into rings and insulators. Always leave extra material if the part will be machined, because machining removes stock.
Tell us the temperature, the chemical or medium in contact, the pressure and whether the part moves or only seals. PTFE can handle temperatures up to about 260 °C and resists a wide range of chemicals and acids, but the filled grades behave differently from virgin PTFE.
Send the product type (sheet, rod, tube, gasket or machined part), the grade, the dimensions and the quantity. Add the application and any drawing. If you need a certificate, ask for the Material Test Certificate; it is provided with every order.
For gaskets, send the flange standard, nominal size and pressure class, or a drawing. For machined parts, a drawing with tolerances is best. See our PTFE gaskets, PTFE envelope gaskets and PTFE machined components pages for the range.
Our main product groups are normally in stock in Dammam, and we ship to all regions of Saudi Arabia. Dispatch is usually within one to three working days for stocked items, and we confirm lead time for custom parts when we quote.
