Tef-Gel Anti-Seize Corrosion Gel — 10g Tube
One tiny tube, one massive problem solved. Tef-Gel is the anti-seize, anti-corrosion and anti-galling gel used by foilers, kiters and marine enthusiasts worldwide to keep bolts, screws and fittings turning freely — no matter how long they’ve been in saltwater. A small amount applied during assembly means no seized bolts, no stripped threads, and no frustration when you need to break down your foil at the end of a session.
Key Features
- Anti-seize — acts as an assembly lubricant so bolts and screws torque correctly and come apart easily for maintenance
- Anti-corrosion — forms a barrier that stops rust and oxidation on metal contact points
- Anti-galling — prevents thread damage between dissimilar metals (e.g. titanium bolts in aluminium masts)
- NSF registered — non-toxic and non-harmful to marine and land-based ecosystems
- Non-reactive and chemically stable — safe on all metals, composites and carbon fibre
- Indefinite shelf life — stays effective in the tube; one application lasts the life of the fastener
- 10g tube — compact size perfect for your kite bag or foil kit

Construction
Tef-Gel is formulated with polytetrafluoroethylene (PTFE) — the same low-friction, chemically inert compound used in industrial sealing and aerospace applications. Its non-reactive base means it won’t contaminate surrounding materials, degrade composites, or react with saltwater. Unlike petroleum-based greases, it won’t wash out or break down over time, making it the go-to choice for foil and kite hardware exposed to constant saltwater cycling.
Why We Recommend It
If you foil regularly in saltwater, seized bolts aren’t a matter of if — they’re a matter of when. We’ve seen titanium mast bolts welded solid into aluminium fuselages after just one season without protection. A tiny smear of Tef-Gel on every bolt at assembly takes 30 seconds and saves hours of frustration (and potentially a ruined component) later.
The 10g tube is the perfect size to keep in your foil bag — enough for dozens of assemblies without taking up any space. We use it on every piece of foil hardware we sell and recommend it to every customer who walks through the door with a foil setup.
Best suited for: Foil riders, kiters, SUP paddlers and anyone using stainless, titanium or aluminium hardware in a saltwater environment.
