Vibra-TITE 125 Medium-Strength Gel Threadlocker — 35 ml Pump, Blue, Removable, Vibration-Resistant

Vibra-TITE 125 is a blue, medium-strength anaerobic gel threadlocker in a 35 ml pump that secures metal fasteners against vibration while remaining removable with standard tools.

This gel-style threadlocker is designed for metal-to-metal threaded assemblies where controlled holding power and the ability to disassemble later are both required. Formulated to cure rapidly on plated or slightly oily surfaces, it replaces mechanical locking devices such as lock washers and plastic inserts and provides resistance to heat, water and many solvents. The 35 ml pump makes application simple for workshop or field use on bolts, studs and hydraulic fittings.

How quickly will Vibra-TITE 125 set and reach full strength?

Cure speed varies with temperature, surface condition and whether a primer is used. With the suggested primer the gel can tack almost instantly, while without primer it typically fixturies in minutes at room temperature. Full polymerization is achieved over 24 hours under standard conditions.

• Fixture with primer: under 1 second in optimal conditions
• Fixture without primer: typically 5–10 minutes at 77°F (25°C)
• Full cure: approximately 24 hours at 68°F (20°C)

Which fastener sizes and joint gaps does it work with?

Vibra-TITE 125 is intended for common bolt diameters and small thread clearances, making it suitable for machinery and equipment fasteners. It seals and locks threads from light to medium-duty sizes while accommodating thin gaps between mating threads.

• Recommended bolt diameters: 1/4" to 3/4" (6–20 mm)
• Maximum gap fill: 0.015 inches (approx. 0.38 mm)
• Designed to replace lock washers, bevel washers, and plastic inserts for these ranges

What mechanical strength and disassembly performance can I expect?

The product provides medium clamping strength that resists loosening from shock and vibration but still allows removal with common hand tools. Measured breakaway and prevailing torque values reflect its medium-strength classification for typical workshop applications.

• Typical breakaway (3/8" phos-oil): 100–130 lb·in
• Typical prevailing (3/8" phos-oil): 40–60 lb·in
• Torque strength measured near 195/70 lbs (Break/Prevail notation)

What storage and handling practices keep Vibra-TITE 125 effective?

Storage conditions influence shelf life and performance. Keep the pump capped and stored at stable, cool temperatures to preserve the formula; refrigerating extends usable life but follow recommended ranges to avoid freezing or overheating.

• Optimal storage: 25 ± 2°C for longest shelf life (18 months from manufacture)
• Refrigeration recommended at 0°C to 35°C when needed
• Shelf life at 68°F (20°C): 12 months; full shelf life 18 months at optimal storage

Who is this for? Vibra-TITE 125 Gel Threadlocker suits maintenance technicians, assembly shops, and field mechanics who need a reliable medium-strength locking adhesive that performs on plated or slightly oily metal surfaces and allows later disassembly. It’s a strong option for gearbox bolts, drive shafts, bearing covers, hydraulic fittings and construction equipment where vibration resistance, leak prevention and the ability to remove fasteners are important. Prepare fasteners by cleaning oil and debris for best results, apply by hand from the 35 ml pump, and choose primer when rapid fixture is required.

• Features:
  • Locks and seals threaded fasteners
  • Resists loosening from shock and vibration
  • Performs better than many mechanical locking devices
  • Reduces rust-lock and helps prevent leakage
