▪ Gaskets
– Always use new gaskets, making sure that they have the same thickness as
the old ones.
– Always fit gaskets of asbestos-free materials or graphite without using
lubricants (e.g. copper grease, graphite paste).
▪ O-rings
– Never use O-rings that have been made by cutting an O-ring cord to size and
gluing the ends together.
▪ Packing rings
– Always use pre-compressed packing rings
CAUTION
Contact of O-ring with graphite or similar material
Fluid could escape!
▷ Do not coat O-ring with graphite or similar material.
▷ Use animal fats or lubricants based on silicone or PTFE.
▪ Assembly adhesives
– For gaskets, avoid the use of assembly adhesives, if possible.
– If assembly adhesives are required, use a commercially available contact
adhesive (e.g. "Pattex").
– Only apply adhesive at selected points and in thin layers.
