FIBREFLEX FCS-47 is a cellulose fibre/cork gasket material with a synthetic
rubber binder.  This material is used for sealing uneven surfaces where high compressibility
and conformability are required.  Colored brown FCS-47 is a low density material with high
compressibility, medium swelling and medium absorbancy.

COMPLIANCE CERTIFICATION: FIBREFLEX FCS-47 is certified to be in compliance with
A.S.T.M. F104-88 F336176, and A.S.T.M. F104-88 P3354A and P3464A.
