Loctite 5990 Premium Silicone Copper Gasket Maker/Sealant is rated out of 5 by 13.Rated 5 out of 5 by Osprey666 from Perfect for exhaust This is a nice easy to apply product coming with a little metal spreader tool. Used on Smart cdi after replacing flexi pipe. I used original metal gasket but used this sealant in conjunction to make the perfect joint. Certainly recommended over any exhaust paste that tends to get brittle with age.Date published: 2018-02-01Rated 4 out of 5 by Sleepless from Exhaust seal Exhaust leak between turbo and catalytic converter. Removed catalytic converter (joined to diesel particulate filter - Peugeot 307SW), cleaned surfaces sealed with Loctite 5990, rejoined with new clamps. Sealant is rated to 250 centigrade, joint measured at 170 centigrade. 1000 miles, OK so far.Date published: 2016-11-18Rated 1 out of 5 by Ornob from Very bad product I will ask people not to buy this..you can trust me this product is very bad..i just wasted my money on buying this product..it can not stick to together with any particle..its sticking ability is really poor..it just messed up the surface wherever you put it..Date published: 2015-10-26Rated 5 out of 5 by Cassim from Excellent to supplement exhaust gasket I bought this product as the exhaust flange on my motorcycle engine was pitted and, despite trying to polish it, some deeper pits remained. Used it to supplement the exhaust gasket and it worked a treat. No exhaust gas leak at all even after 2000 miles. Strongly recommended.Date published: 2015-04-29Rated 4 out of 5 by KiwiG from 1978 Triumph T140v casing e.t.c Used instead of fiddly paper gaskets & as additional sump plug seal with respective copper washers.

It's superior bonding and heat resistance is fantastic and has NEVER let me down. I highly recommend this product and will myself continue to use it.Date published: 2014-12-27
