TEF GEL Syringe

From 28.20 

TEF-GEL® is a watertight, PTFE-based paste which can be used universally.

  • Prevents metal from blooming and protects reliably against corrosion by means of galvanic currents between different types of metal.
  • Seawater-resistant lubricant and for sealing purposes to prevent water from penetrating.
  • Used in the boat,bike & automotive industry, in aviation and aerospace and wherever parts have to be protected from corrosion.
  • Contains 0% volatile solvents, TEF-GEL® will no evaporate, cold flow, or dry out, giving protection many years later when hardware must be dissembled.


TEF-GEL® is a watertight, PTFE-based paste which prevents the blooming of metal and also reliably prevents corrosion from galvanic flows between unequal metals. In all places where refined metals come into contact with less refined metals (e.g. aluminium with special steel), a small amount of TEF-GEL® suffices to prevent galvanic exchange of electrons and subsequent corrosion.

Assemble your bolted connections with TEF-GEL® and every connection is easy to disconnect even after intensive use in sea water. The same also applies to corrosive locking of set screws, shroud clamps or other bolted connections.
Tef-Gel applied to both mating surfaces of nuts and bolts or threaded holes and bolts leaves a layer of 40% solid PTFE within the thread interface, which works as friction barrier.

Tef-Gel®, which contains 0% volatile solvents, will no evaporate, cold flow, or dry out, giving protection many years later when hardware must be dissembled. It protects connections of various metals, and screw connections are kept workable permanently.


  • Stops corrosion of stainless screws in aluminum and any other dissimilar metal corrosion
  • Stops seizing, assemble with Tef-Gel and disassemble with ease
  • Stops galling of stainless bolts and nuts
  • Tef-Gel® does not electrically insulate hardware or electrical connections


TEF-GEL® is applied to the surface to be protected, smoothly and evenly, directly from the tube or using a small brush. TEF-GEL® never dries up, which means there is no processing time. Use turpentine to clean tools or surroundings.

  • Cleaning : mineral spirit
  • Storage: open container >10 years
  • Consistency: pasty
  • Combustion point: > 230 °C
  • Processing temp.: -20 °C bis +45 °C
  • Density: approx. 1.077 g/L
