🔧 Lock it down with Loctite 272 — where strength meets heat resistance!
Loctite 88442 Red 272 is a professional-grade, high-strength threadlocker designed for high-temperature applications. It cures quickly on most surfaces, including new fasteners, providing a permanent, vibration-resistant bond that requires heat and tools for disassembly. Packaged in a 50 mL bottle, it’s ideal for engine rebuilds and demanding mechanical projects where reliability under heat and stress is critical.

I could never find these locally
Works as intended. Stronger than blue. Used this on my bed frame bolts about two weeks, so far so good. Only time will tell.

Good Product
Seems to be genuine Loctite. On the bottle is states "For sale in India only". I'm in the US, so have no idea what that is all about.

Perfect for an engine rebuild, high strength that actually holds
Used this Loctite 272 red threadlocker during an engine rebuild and it did exactly what I wanted: it kept critical fasteners from backing out while dealing with heat, vibration, and repeated torque checks. Once it cures, it is seriously solid. No surprise loosening, no mess, and a little goes a long way. The 50 mL bottle is a nice size if you are doing a full rebuild or multiple projects, and the liquid applies cleanly without globbing everywhere. I had best results by cleaning the threads first, applying a small amount, and giving it proper cure time. One thing to know up front: this is high strength. If you plan to remove the fastener later, expect to need heat and the right tools. For permanent or long term assembly on an engine, that is a plus. Would buy again for any rebuild or high heat application.

Not good to ship in winter.
I love Loctite and have been using their products for many years. This on came frozen from the UPS truck. I called Loctite and was told they have tested this product in much colder conditions. But to be safe, he said, I should use it within 30 days after opening. I guess I won't order any more until summer.

Bottle is intentionally half full and is over-sized for air gap to prevent curing in bottle per Mfr
Product worked to specification withing advertised cure time as expected with all quality Loctite products. ALL thread lockers by Loctite and other manufacturers are sold in a bottle that was intentionally manufactured over-sized to allow adequate shelf life as advertised to specified expiration date, 24 months after manufacture; ATTENTION to previous buyers who have left poor reviews because they thought they received only half of what they paid for expecting a filled to the top container, if it were filled with no oxygen it would have been hard as a rock once received at your door, if your bottle looks half full, as it is supposed to be, that is because that is the only way how anaerobic adhesives like Loctite are able to be sold longer than 24 hours after manufacture; No air/oxygen = cure time/hardening begins, Adequate air gap in container = Longer Shelf Life
