Review: Essential for a secure fit without the headache - Used this for a PCV valve installation on my 4runner, and it’s exactly what I needed. Since this stuff is oil-resistant, I don't have to worry about it breaking down in the engine bay. The best part about the Blue 243 is the peace of mind—it’ll keep the valve seated and prevent it from vibrating loose, but I shouldn't have a tough time removing it later when it's time for the next swap. It’s a solid middle ground between "vibration-proof" and "serviceable." If you're doing your own maintenance on a Toyota, this tube is a must-have for the toolbox. ## Features - Fit type: Vehicle Specific ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B004L439FE | | Best Sellers Rank | #2,530 in Automotive ( See Top 100 in Automotive ) #9 in Thread Lock Sealers | | Brand | Loctite | | Brand Name | Loctite | | Color | Blue,Red | | Compatible Material | Aluminum, Stainless Steel | | Container Type | Tube | | Customer Reviews | 4.8 out of 5 stars 3,297 Reviews | | Full Cure Time | 24 hours | | Global Trade Identification Number | 00079340439078 | | Included Components | (1) 243 Threadlocker for Automotive, Blue, 6-ml | | Item Form | Liquid | | Item Package Quantity | 1 | | Item Type Name | automotive-thread-lock-sealers | | Manufacturer | Loctite | | Material | Aluminum , Stainless Steel | | Material Type | Aluminum,Stainless Steel | | Model | 1330799 | | Number of Pieces | 1 | | Part Number | 1330799 | | Specific Uses For Product | Automotive, Mechanical | | UPC | 079340439078 | | Viscosity Level | Medium | | Volume | 6 ml | | Water Resistance Level | Water Resistant | ## Product Details - **Brand:** Loctite - **Color:** Blue,Red - **Item Form:** Liquid - **Material:** Aluminum,Stainless Steel - **Specific Uses For Product:** Automotive, Mechanical ## Images ![Loctite 243 - Image 1](https://m.media-amazon.com/images/I/81InQQNOf1L.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: is there a loctite that resists gasoline ?** A: Most of our Loctite anaerobic sealants and threadlockers will resist gasoline once they're fully cured. The right product will depend on your application requirements. Please call 1-800-LOCTITE (562-8483) to receive a product recommendation from one of our engineers. **Q: How do I open the Loctite 243 bottle?** A: You simply twist the cap and it should open. **Q: Is this good to use on battery cable bolts?** A: Yes this can be used on the threads. Loctite 243 is a plastic so keep it off the post where good electrically conductive contact is required. I am thinking a car battery here. If this is a different design and IF THIS THREADED ASSEMBLY REQUIRES ELECTRICALLY CONDUCTIVY DO NO USE OUR PLASTIC THREADLOCKER IT WILL INSULATE AND GENERATE RESISTANCE. **Q: Can this still be effective on a bolt that is threaded, left to sit, and then threaded again to torque spec?** A: Left for set how long? When you remove the bolt, if it's still wet then yes, but I would wipe it off and reapply because I would want a thicker application for a tighter bond. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Loctite 243 Oil Resistant *by F***R on July 4, 2026* Loctite makes great products you can have confidence in. ### ⭐⭐⭐⭐⭐ Essential for a secure fit without the headache *by M***N on April 11, 2026* Used this for a PCV valve installation on my 4runner, and it’s exactly what I needed.
