Auto Maintenance and More: When and Why to Use Purple Threadlocker

    July 11, 2013

I have always been a firm believer in the products I sell.  That being said, it is also important to me that my customers believe in them as well.  In working with customer’s everyday, I always get the common question, “What is the difference between Red and Blue Threadlocker?,” but lately, more and more people are getting excited about our Purple Threadlocker, Loctite® 222™.

Purple loctite threadlocker

Loctite® Purple Threadlocker has many uses; from carburetor screws to eyeglasses to small screws on laptops. Due to its low strength, it can be removed with the same tool used to put the project together.  It is available in an easy-to-use liquid application, which makes the product especially efficient with very small screw applications, less than ¼ inches in diameter. In the feedback we receive from customers, many use it on automotive maintenance and motorcycle maintenance applications such as carburetor screws and firearms. One customer said it “worked great for a crown knob that came loose from the stem” in reference to a wristwatch repair.

One user posted on Amazon that they used the product on their laptop computer because of several screw problems. The customer commented that Loctite® 222™ “was perfect to keep them [the screws] in, but still removable just in case I had to get back in there”.

Not Just for Vehicle Maintenance

Overall, this product has a broad array of uses to cater to many applications. Its low strength makes it perfect as it can be removed and resealed. Like all of our threadlockers, the purple increases safety, prevents loosening, leaks and corrosion. Long term, this means less money spent on visits to the repair shop.

If you have tried Loctite® 222™ low-strength, purple threadlocker, please let me have your feedback! If you would like to try it, you can purchase it at a local distributor, or on Amazon.

    I too use Loctite 222 for a non-conventional application; I had some fastener issues with a new holster that I absolutely LOVE …Alien Gear Cloak Tuck 3.0 Inside The Waist Band style, The screws go into “T” nuts/Poly Nuts, and they loosened up on me a couple of times, NOT good ! You don’t want your gun popping out of your holster, which will (a) damage the weapon, and (b) cause unwanted attention when your weapon lands on the ground in a crowded store !!!. I put a little blue Loctite 242 on the screws at first, and it worked a little too well…the screws are fairly small and I was afraid of thread damage because this holster is modular, and screw removal is necessary to adapt it. So looking here I discovered the Purple 222, and it fits the bill perfectly. Screws stay put, and when it comes time for removal, it’s very easy. The Purple 222 is kind of like a hardened,rubbery consistency when cured and keeps the screws where I need them. Even if they were to loosen up, The purple won’t let them back out as to where I could lose them. They NEVER did loosen though. Perfect !!! Thank You very much for an awesome product !

      Hi Timothy – In many cases you could use LOCTITE 425 in place of 243. However, they are not the same chemistry, so there would be some differences when using either one. If you would like more specifics or have any more questions, please contact us at (800) 562-8483. Thank you!

    I use Loctite 222 for my recumbent tricycle. I ride with SPD cleats and pedals, and one day I lost one of the two bolts holding my left cleat in place, mid-ride.

    Cleats wear out and need to be replaced every so often, so it was important I be able to remove it again. With the shoe’s bottom being plastic, Red was right out – that much heat would possibly ruin the shoe itself. Even using Blue was questionable, because it requires significant force to release, and at some point the plastic around the shoe’s metal receiving plate might fail if the force needed was high enough.

    The Purple 222, on the other hand, is just about perfect! 🙂

    I also use it to keep the bolts securing my disk brakes in place (lost one of THOSE once, mid-ride, too – never again!), and a few other places on my cycle.
