Special grease for installing stainless fittings. It does two things: prevents galling (seizing, cold welding) and reduces the coefficient of friction, so the torque you apply goes into clamping rather than being lost to friction.

| Product name | ABF Anti-Bloc-Fett (Antibloc-Grease / Graisse-Anti-Bloc) |
|---|---|
| Maker | Eaton Walterscheid — made in Germany |
| For material | Stainless 1.4571 (AISI 316Ti) |
| Function 1 | Avoid gripping — galling, seizing, cold welding |
| Function 2 | Reduce the friction coefficient for torque conversion |
| Application | Brush or lint-free cloth, to all contact surfaces |
| Packs | Tin (workshop) · tube (site) |
| Material | What happens under contact load |
|---|---|
| Plated carbon steel | The zinc or zinc/nickel layer shears preferentially — it is sacrificial. The fitting is designed around that friction figure. |
| Austenitic stainless | There is only a thin oxide film. It breaks down under contact load, bare metal meets bare metal, and the two cold-weld and tear. |
The timing is what makes it expensive: this failure happens on first assembly, often before final torque. A seized stainless fitting has to be cut out, not undone — and on an installed line, that means remaking the joint from scratch.
Surfaces must be clean before greasing — dirt trapped under grease still scores.
Lint-free because fibres left behind go into the system and circulate with the oil to the filters.
Thread flanks, ferrule cone, nut face. A sufficient amount — do not pack it: excess gets pushed into the fluid, where it becomes contamination.
Immediately after greasing. Greased fittings left on a bench collect dust and grit — which is then dragged across exactly the surfaces you were protecting.
ABF changes friction, not method. Eaton instructs you to follow the assembly instructions for the respective fitting system — turns, torque and the ferrule-bite procedure remain as specified. See the assembly procedures on the DIN 2353 fittings and double ferrule pages.
| Not… | Why |
|---|---|
| Not a thread sealant | The fitting seals by its design — ferrule bite, 24°/37° cone, or an O-ring. For tapered threads, use a proper thread sealant. |
| Not a general-purpose grease | Ordinary grease lubricates but is not formulated to stop stainless cold-welding under contact load — symptoms reduce while the surfaces still gall. |
| Not needed on plated carbon steel | Zinc or zinc/nickel plating already does the job. Use ABF only for stainless on stainless. |
Data note: Eaton's sheet for this product states the function, the material and the application method, but does not publish a temperature range, an NLGI grade or the composition. If your project specification calls for those figures, we will confirm them with the factory on request.
Two things. It avoids gripping — galling, seizing, cold welding — and it reduces the coefficient of friction so torque goes into clamping rather than friction loss. Eaton describes it as a special grease for the installation of stainless couplings in material 1.4571.
Plated carbon steel has a zinc or zinc/nickel layer that shears preferentially. Stainless has only a thin oxide film — it breaks down under contact load, bare metal meets bare metal, and the two cold-weld. The failure typically happens on first assembly, before final torque.
No. The fitting seals by its own design — ferrule bite, a 24° or 37° cone, or an O-ring. The product has no sealing function. For tapered threads, use a proper thread sealant.
Ordinary grease lubricates, but it is not formulated to stop stainless cold-welding under contact load. The risk is that symptoms reduce while the surfaces still gall — and a seized stainless fitting has to be cut out, not undone.
Enough to film all contact surfaces — thread flanks, ferrule cone, nut face. Eaton specifies “a sufficient amount”. Do not pack the fitting: excess gets pushed into the fluid, where it becomes contamination.
Because fibres left inside a fitting go into the system. On stainless lines they circulate with the oil and reach the filters. Same reason the surfaces have to be clean before greasing.
No — assemble immediately after greasing, to avoid contamination. Greased fittings left on a bench collect dust and grit, which is then dragged across exactly the surfaces you were protecting.
It changes friction but not method. Eaton instructs you to follow the assembly instructions for the respective fitting system — turns, torque and the ferrule-bite procedure remain as specified.
No. Zinc or zinc/nickel plating already does the job, and those fittings are designed around that friction. Use it only for stainless on stainless.
Two pack forms: a tin for the workshop bench (brush application) and a tube for the site toolbox. A little goes a long way, so most orders are small.
