We can guarantee premium quality FFPM o-rings that are minimum Equal in quality to Kalrez®.
Our biggest advantage is that we have the biggest range of standard compounds and special compounds available in stock in high quantities in a huge range of sizes. Whatever FFPM O-ring you are looking for, we have it on stock.
What is an FFKM O-ring?
O-rings from FFKM are materials that can be most stressed chemically and thermally. Some O-ring types of FFKM can handle temperatures of +300 °C. The resistance of the FFKM O-ring to chemicals is almost universal and comparable to that of an Oring PTFE. The advantage of the O ring fkm is the difference that it can be used both chemically and thermally.
Operating temperature:
• -15 °C to +270 °C.
• Available with special qualities: -40 °C to +340 °C.
FFKM Orings are highly resistant to:
• Almost all chemicals
• Ozone, weather conditions, aging
FFKM O rings are not very resistant to:
• Fluorinated compounds
