Rated 4.5 out of 5 by 12 reviewers.Rated 4 out of 5 by Sleepless 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. 18 November 2016Rated 1 out of 5 by Ornob 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.. 26 October 2015Rated 5 out of 5 by Cassim 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. 29 April 2015Rated 4 out of 5 by KiwiG 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. 27 December 2014Rated 5 out of 5 by Verified Reviewer Great even for exhaust manifold!! I used the Loctite 5920 as a sealant on inlet manifold gasket and on exhaust (!!) manifold gasket in my Pajero 2.5 TD and I couldt be more happy. Perfect product and very good price.
