FIBREFLEX MT-540 is a non-asbestos homogeneous gasket material produced by the
beater-addition process.  Characterized by its grey/black color, this material is manufactured
with a blend of nitrile latex and fibrous reinforcing materials which results in a product
of high density, good fluid resistance, good dimensional stability and flexibility, which is
suited for higher temperature applications.  *Actual temperature range will vary depending
on the particular application.

COMPLIANCE CERTIFICATION: FIBREFLEX MT-540 is certified to be in compliance with
A.S.T.M. F104-88, F724155E43M5.
