Quick-Seal Multi 9654/MB


Quick-Seal Multi 9654/MB sealing tape consists of virgin multidirectional expanded PTFE. The modern production process creates a multidirectional fiber structure that gives the seal its special properties.


  • High dimensional stability
  • Outstanding compressive strength
  • Excellent adaptability
  • Minimum cold flow properties
  • Universal media resistance
  • Easy handling

Operating range

Pressure: The pressure resistance depends exclusively on the installation and operating parameters (please read our installation and maintenance instructions).
  • Continuous operation:
    t = -240 °C ... +270 °C
  • transient peak temperature:
    t = +315°
Recommended surface roughness:
RZ = 12.5 ... 50 μm

Chemical resistance: pH = 0 … 14
Not suitable for use when melting alkali metals or in hydrogen fluoride and fluorine compounds at t > 150 °C and p > 40 bar.

Sealing parameters
AD Directive B7:
  • kO x KD = 25 x bD
  • k1=2,5 x bD
  • DIN 28090-2:
  • εKSW = 39 %

Standards and approvals

  • EC 1935/2004 (without adhesive)


Easy to fit on site. Shape and length can be cut to size by hand. No waiting or curing times. The sealing tape does not age. The adhesive life depends on the storage and installation conditions. The tapes can also be doubled or spliced to take account of extreme flange conditions, distortion or irregularities.

Elastic Tankpak 6756

EagleBurgmann Elastic Tankpak 6756 is an excellent gasket for sealing transport containers for chemicals or solvents. The core is made from a hollow elastomeric material (EPDM) wrapped in PTFE foil, thus guaranteeing optimum chemical resistance for the entire seal. The polypropylene middle layer primarily acts as a cushion and buffer, and it is first wrapped with PTFE foil. The entire seal is then over-braided with PTFE yarn, fixing it firmly to the rest of the material composite.
