Green FKM Fluorine Rubber O-Rings - 3mm Cord Thickness, OD From 8mm To 520mm

Need a tough, chemical-resistant seal?

These are green FKM (fluoroelastomer, often called Viton) O-rings.

They're brand new and unbranded.

The key spec is the 3mm thick cord (cross-section diameter).

The outer diameter (OD) ranges from as small as 8mm all the way up to 520mm, so this is likely a large assortment or you specify the size you need.

FKM rubber is famous for handling high temperatures, oils, fuels, and many aggressive chemicals.

They're perfect for automotive, aerospace, industrial, and plumbing applications where a standard rubber O-ring would fail.

Made in China.

Whether you're repairing a fuel system, a hydraulic fitting, or industrial equipment, these O-rings offer superior durability.
