• Corrosion, fretting or erosion across the mating face

Service / Installation Notes:

  

• Remove all old sealing material without damaging the mating faces and confirm the correct seal grade or thickness.

• Lubricate only where specified, install without twisting, and pressure-check the system after assembly.

• Select gasket grade from measured piston protrusion; do not rely only on the marking of the removed gasket.
