Sealing elements 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 Avoid the use of assembly adhesives if possible.
Should an assembly adhesive be required after all, use a commercially available
contact adhesive (e.g. Pattex) or sealant (e.g. HYLOMAR or Epple 33).
Only apply adhesive at selected points and in thin layers.
Never use quick-setting adhesives (cyanoacrylate adhesives).
Coat the locating surfaces of the individual components with graphite or similar
before reassembly.
Tightening torques For reassembly, tighten all screws and bolts as specified in this manual.
