Used properly ULTRA Tef-Gel is the ultimate anti-seize, anti-corrosion lubricant available to the public. Stops and prevents Galling, Seizing, and Blistering in any marine application. Bottom line: PTFE synthetics have rightfully earned high marks for their anti-seize protection. Best Buy. Conclusion

The application guidelines are to be used in conjunction with the product Material Safety Data Sheet and application information printed on the product label.

This project should be framed as a comparison between examples from each of the two categories of greases-organic vs. synthetic. It is not a strict head-to-head test. Lanocote is derived from sheep lanoline, one of the worlds oldest greases, while polytetrafluoroethylene (PTFE, aka Teflon) is a 20th century synthetic. There is a range of similarly formulated products in either category that we expect would deliver comparable results. (Forespar makes its own synthetic product, Marelube TEF 45, that would be a better match for Tef-Gel in a true head-to-head.) Lanocote

Whether you go to sea for work or play, protecting your floating investment from saltwater’s destructive force is critical. We recommend using PTFE based ULTRA Tef-Gel everywhere saltwater touches joining metals. ULTRA Tef-Gel is ideal for aluminum boatsTef-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. Tef-Gel is a made with a water resistant coating that prevents oxidation of metal and paste corrosion due to the flow galvaniques between different metals.

Use mascara brush, bottle brush, or toothbrush to apply a thin coat of Tef-Gel to both the threaded hole and the bolt threads and tighten. (Torque requirements may have to be altered according to application of thread lubricants). However, we use Tef Gel in assembly to eliminate the risk of galvanic corrosion between dissimilar metals. This brilliant American-made (as used by the US Navy!) product is difficult to find in the UK, so we decided to sell it to UK yachtsmen. Any items that we deem unhygienic will not be processed so please clean faulty goods if returning them.

Specification

Tef -Gel ™ is derived from a specially formulated Teflon® paste & is used in high corrosive environments to ensure serviceability & presentation of assembled hardware. ​ Tef-Gel™Applications ​

Tef-Gel applied on both surfaces and bolt or nut bolt and threaded solid leaves a film of PTFE, which prevent drill steel 18/Corrosion. Tef -Gel ™ paste contains 40% PTFE powder and 0% volatile solvents, no silicone's or petroleum solvents to evaporate, which would leave voids for electrolytes to be drawn into creating a galvanic cell. When both surfaces are coated and mated with Tef -Gel ™ there are no voids for electrolytes (saltwater) to be drawn in by capillary action over extended periods of time.Tef-Gel™ must be applied liberally to all surfaces prior to assembly including threaded fasteners and flat surfaces of hardware including washers. Failure to adequately apply Tef-Gel™ will result in a reduction in protection. Any excess Tef-Gel™ can be removed with Mineral Spirits, (Mineral Turpentine) to leave an airtight barrier of protection. Ensure clean up products are used within the guidelines of the product suppliers and the respective Material Safety Data Sheets.
