## Description

OEM approved - use where OES specify 515 or "anaerobic" gasket (cures in absence of air). Eliminates preformed, pre-cut, paper, rubber, and cork gaskets. Flexes with flanges that move in service.Gasketing product for machined metal flanges. Medium strength. 30 min fixture time. Can also fill gaps up to 0.25 mm.LOCTITE 515 is a medium strength (6 N/mm² tensile shear strength), medium cure speed, methacrylate-based industrial gasketing product designed for machined, rigid metal flanges. The product, which cures anaerobically, is suitable for gaps up to 0.25 mm. It is used typically as a form-in-place product for pumps, thermostats, compressors, transmission housings and axle covers. Ideal for machined metal components.LOCTITE automotive aftermarket products are not just OEM-specified, they are also designed by auto manufacturers and lab tested. Engines of nearly every professional race car are assembled and maintained with LOCTITE brand adhesives, sealants, gasket makers, and coatings. Whether gasoline or diesel, from bolts and gaskets to cooling lines and core plugs, Henkel products are used to seal, secure, and repair vehicle components.

Review: stopped the leak - After doing quite a lot of research I decided to give this a try. I have an old Speedaire air compressor that had a leak from the valve plate gasket for which a replacement is no longer available. The gasket is subject to high compression and excessive heat. After attempting to make a replacement from gasket material (which nearly worked but still leaked minutely) I assembled the compressor using this product and it has performed flawlessly: no leaks. It is critical that the mating surfaces are extremely clean before applying. It does set up to a thick gel consistency but it does not harden which many other products do. A bit more costly than many other sealants but worth it.
Review: Excellent product at an excellent price!!! - Been using the stuff for decades on snowmobile engines, and other applications. The best of the best. Great price here by far!!!

## Questions & Answers

**Q: Does it work on plastic engine parts? The cylinder on my chainsaw mounts to plastic.**
A: It does not work on plastic. The product is activated by metal ions, so it fully  cures only in presence of metal.

**Q: will this work for diesel exhaust manifold block off plate with high temps?**
A: This product can only resist up to 300-350 degrees F, not recommended for exhaust manifolds. The metallic gasket is the only thing that will create a proper seal for those temps of a diesel engine.

**Q: Can I use 515 to seal around the leak for automatic transmission fluid around the dipstick tube as it connects to the chevy automatic transmission?**
A: 515 is primarily an anaerobic, used to prevent air leakage between torqued surfaces. I have used it on gear cases and power equipment transmissions with success.  It may work on your dipstick, if you can secure it so it doesn't move around. Of all things JB weld may be a better repair.

**Q: What is the shelf life**
A: There is no shelf listed on tube I have used it well past  year on Engines case halves
