Vibra-TITE medium-strength gel threadlocker 35 ml pump, Blue — removable, anti-vibration seal

Vibra-TITE 125 Gel is a medium-strength, removable anaerobic threadlocker in a 35 ml pump that locks and seals metal threaded fasteners against vibration while allowing later disassembly with standard tools.

Designed for use on a wide range of metal fasteners, Vibra-TITE 125 cures into a tough adhesive seal that prevents loosening from shock and vibration and reduces leakage and rust-lock. The gel formulation works well on plated or lightly oily surfaces and in slightly inactive conditions where liquid threadlockers might drip or run. Packaged in a convenient pump bottle, this blue medium-strength formula is intended for nuts and bolts between 1/4" and 3/4" (6–20 mm) and fills gaps up to 0.015".

How quickly will Vibra-TITE 125 hold fasteners during assembly?

The threadlocker begins to fixture fasteners within minutes and reaches full strength over 24 hours at room temperature. Using the recommended primer cuts initial fixture time dramatically on inactive or oily surfaces.

• Fixture speed without primer: typically 5–10 minutes at 77°F (25°C)
• Fixture speed with primer: under 1 second on qualifying surfaces
• Full cure: 24 hours at 68°F (20°C)
• Stored: refrigerate 0–35°C for best shelf life

What fastener sizes and materials is this gel suitable for?

Vibra-TITE 125 is formulated for metal threaded hardware and works on a variety of plated and unplated metals. It covers common machine fasteners used across industrial, automotive and equipment applications.

• Recommended fastener diameter: 1/4" to 3/4" (6–20 mm)
• Maximum gap fill: 0.015 inches
• Typical breakaway strength on 3/8" phos-oil: 100–130 lbs·in
• Typical prevailing strength on 3/8" phos-oil: 40–60 lbs·in

How does this product perform against vibration, temperature and solvents?

The medium-strength gel resists loosening from shock and vibration and offers good temperature and solvent resistance for many industrial uses. It replaces mechanical locking devices where controlled removability is required.

• Designed to stop fasteners loosening from vibration and shock
• Good resistance to water and non-polar solvents
• Performs better than lock washers and plastic inserts in many applications
• Helps prevent rust-lock and leakage at joints

What storage and handling details should I know?

To maximize shelf life and preserve performance, store Vibra-TITE 125 at stable, cool temperatures and keep parts clean before application. The product dispenses easily from the pump for controlled, hand-applied coverage on threaded parts.

• Container: 35 ml pump bottle for precise application
• Shelf life: 12 months at 68°F (20°C); up to 18 months when stored at 25 ±2°C
• Suggested primer: N or T for inactive surfaces
• Application: clean, dry fasteners; hand apply from bottle

Who is this for: Vibra-TITE 125 Gel is aimed at maintenance technicians, equipment assemblers, automotive and industrial mechanics, and anyone who needs a reliable, removable locking adhesive for machine bolts, studs, gearbox and bearing cover screws, conveyor hardware, and hydraulic system fasteners. It’s especially useful when vibration resistance and future disassembly with standard tools are both required.
