  • economical gasket tape made of high-quality ePTFE (oriented, expanded material)
  • handy, easy to instal: no punching; the fitting gasket is formed directly off the coil: round, square, longitudinal, uneven etc.
  • universally applicable as static gasket in almost all areas, e.g. heat exchangers, pipelines/flanges, columns, casings - for steel flange, flat or with grooves and spring - for oxygen lines in copper/ copper base alloys (see BAM-approval)
  • Specifically suited for FRP and plastics flanges, glass/graphite devices, sight glasses, ceramics flanges etc. because of its excellent mouldability quality

Approvals / tests:
BAM-tested, TgbNo. 5421/83/4-1906I:
No reservations concerning safety regulations with use of gaseous oxygen within the corresponding range of pressure and temperature
  • CHETRALON® substitutes the conventional square packing, esp. with smaller cross section: coil it into the stuffing box compartment and tighten with gland/follower nut ("50% compressed")
  • "Instant" seal custom-made - excellently mouldable PTFE-core, supported by PTFE spiral casing, guarantees versatile filling of the sealing compartment, at the same time limiting the cold flow - no pressing out of material or "obstruction" of spindle
  • universally applicable in chemical and pharmaceutical industries, mechanical engineering, heating installations, domestic technique, in the agricultural area or with steam use a.o.

Approval/ Correspondence:
Corresponds with FDA-stipulations
  • MPG is a high-quality system for the production of gaskets for most industrial areas of application
  • Unevenness in flanges up to 7 mm can be levelled out - MGP is shape permanent, does not shrink or get warped or off-center
  • easy installation (s. diagram) and disassembly - easy to strip without caking together, goes easy on flanges
  • economical application; no waste, no cutting to size, no punching
  • resistant to water, oils, hydraulic liquids, solvents, chemicals etc. (except concentrated acids and alkaline solutions; (s. pH-range)
