TOMBO™ No. 2670-FA-F Rubber O-ring Fluoro-Plus (Special FKM)

TOMBO™ No. 2670-FA-F

Rubber O-ring Fluoro-Plus
Fluoro-Plus is a special fluoroelastomer (Special FKM) that maintains the chemical resistance and heat resistance of a regular fluoroelastomer but has significantly improved wear resistance and non-stickiness.
Fluoro-Plus is different from outer membrane coatings and is a product that undergoes treatment by way of a surface improvement method. As a result, it maintains its attributes over the long term and it experiences no peeling of the surface layer.

Features

Heat resistance guide*: 200°C
Standard hardness (Duro A): 70
It Its friction coefficient is about 1/2 of a standard fluoro elastomer.
Its adhesion with metal is about 1/5 of a standard fluoro elastomer.
It undergoes surface modifying processing and so there is no peeling of the surface layer.

Applications

Sealing of parts that continuously slide or move along a surface, parts that open and close repeatedly (sealing of various control valves), and parts that adhere strongly to metal and are difficult to maintain

Precautions for use

Fluoro-Plus is less adaptable to mating surfaces than Fluoroelastomer FA, so do not use it for applications that require a high vacuum seal.

Non-adhesive
