New Loctite® QuickTape™ 249™

New Loctite® QuickTape™ 249™: the first threadlocker to combine the trusted performance of Loctite threadlockers and the familiar, easy-to-use tape format. It’s neat, clean and couldn’t be easier to apply. Just peel the tape from the spool, wrap the tape around the bolt, and tear. This convenient package is a must for every toolbox.

Like all Loctite® Threadlockers, QuickTape™ 249™ reliably locks threaded fasteners from vibrational loosening and seals threads preventing rust, corrosion or leaks.

Key Features

• Medium strength allows parts to be disassembled with hand tools
• Toolbox/Tool belt/Pocket friendly
• No mess
• Can be pre-applied for future assembly

Large Fastener Threadlocker with NEW PATENTED LOCTITE® TECHNOLOGY

This tough threadlocker meets your most demanding requirements, with the strength and temperature resistance that masters demanding conditions, time after time.

Loctite® 2047™ High Lubricity High Strength Threadlocker

• Black - for applications with large fasteners over 7⁄8” in diameter
• New formula reduces friction and attains higher clamp load than Loctite® 277™
• High strength properties resists effects of vibration, maintains clamp load
• Fixture cure in 90 minutes, full cure in 24 hours

Loctite® 5452™ Fast Cure Thread Sealant

Loctite® 5452™ Fast Cure Thread Sealant - for Sealing High Pressure Gaseous and Fluid Power Systems.

Benefits of the Loctite Hydraulic & Pneumatic Sealants:

• Seal and secure used or new metal pipes and fittings by filling the air space between the threads
• Contains no fillers or particles that could contaminate system fluids, foul valves, or clog fine filters or screens.
• Locks fittings from vibrational loosening, while controlled strength assures easy disassembly

Added benefits of the new Loctite® 5452™:

• Immediate low pressure sealing
• Fast cure speed, on average 4 times faster than traditional anaerobic sealants
• Gel formula, well suited for any size NPT, O-ring boss (ORB) or JIC fittings, even large fittings, gaps or threads
• Seals mating surfaces of flare style fittings, filling scratches and surface imperfections
• Works well with dry seal fittings, such as ORB style connectors to prevent rotation that ultimately leads to leakage
• Primerless formula cures quickly even on stainless or inert metals
