Camprofile serrated gasket 9588


The serrated gasket 9588 has a concentrically-machined profile based on a 4 mm thick stainless steel base plate. This is coated on both sides with a 0.5 mm thick layer of pure graphite (purity > 98%). Thicker layers are available on request. The serrated gasket 9588 is easy to handle and is particularly suitable for applications in the chemical and petrochemical industries and in power station technology.


  • Maximum compressive strength
  • Low minimum surface pressure required
  • High temperature stability
  • Ideal for withstanding temperature/pressure cycling

Operating range

Pressure: p = 400 bar
Higher pressures available on request
  • Continuous operation:
    t = -200 °C … +550 °C
Recommended surface roughness:
Rz = 12.5 ... 50 μm

Chemical resistance: pH = 0 … 14


  • Serrated ring: Standard 1.4541 and 1.4571
  • Gasket overlay: Statotherm pure graphite, purity > 98%

Standards and approvals

  • TA-Luft
  • Fire-Safe (API 607)


9598/P graphite layer (purity ≥ 99,85%) for nuclear applications
95.../P (without centring ring - Form NR)
95.../...Z (with centring ring - Form IR or LR)
95.../...B (convex form)
9598/SIL (silver sealing foil, 0.5 mm thick, for t < 700 °C)
9598/T (PTFE foil, 0.5 mm thick, for t < 250 °C)
9598/HT (serrated ring made of 1.4828 with glimmer layer for t < 950 °C)


After the initial warm-up, we recommend retightening the bolts (with the system depressurized) in order to compensate for any minor settling of the overlay material and thus maintain optimum surface pressure. If the gasket is replaced, the undamaged serrated profile ring can be reused.
