GT7 is a professional, non-greasy multi-spray of premium quality, developed for lubricating, releasing and protecting cylinders, locks, multipoint locking systems, hinges, fittings, locking mechanisms and various technical components.

Popular among technical services, maintenance professionals and government agencies.

GT7 penetrates extremely fast, displaces moisture, breaks down rust and restores smooth operation of mechanical parts — ideal for maintenance, troubleshooting and interventions.

🔑 Why professionals choose GT7

• Suitable for all types of locks, cylinders and multipoint locking systems

• Loosens stuck components quickly (sticky latches, stiff lockcases, rusted hinges)

• Improves the operation of poorly closing doors: a small amount on the latch helps the door fall smoothly into the strike

• Supports cylinder pulling: penetrates deep into the cylinder housing, allowing pull screws to turn more smoothly and reducing breakage

• Ideal for maintaining door and window hardware in residential and commercial buildings

• Non-greasy → does not attract dust or dirt

• Immediately restores smooth movement of rotating parts

✔️ Key applications & functions

1. Penetrating oil – frees what is stuck

GT7 penetrates into microscopically small openings.
Ideal for:

• seized cylinders

• blocked lock mechanisms

• squeaking or rusted hinges

• stiff multipoint locking systems

• metal components that no longer move

2. Deep-penetrating moisture displacer

GT7 pushes moisture away instantly in cases of rain, condensation, leakage or frost.
Restores the operation of:

• moisture-affected locking parts

• oxidised mechanical components

• electronic locking systems

3. Powerful rust breaker

Breaks down rust crystals and works faster thanks to the cold-shrink effect.
Screws, strike plates, fittings and mounting parts come loose more easily.

4. Contact spray for electronic systems

Suitable for:

• electric locks

• door openers

• magnetic plates

• access control systems

• junction boxes

• wiring and connectors

Removes oxidation and restores conductivity.

5. Effective cleaner

Removes:

• old oil

• grease

• dust and dirt

• tar residues

• brake dust

• deposits in lockcases, cylinders and mechanisms

• general technical contamination

6. Non-greasy lubricant

Ensures long-lasting, clean and smooth operation of:

• cylinders

• mortise locks

• multipoint locks

• hinges

• window and door hardware

• precision components

No dirt build-up, no sticky residue.
