Permatex 77134 Nickel Anti-Seize Lubricant, High-Temp Protection up to 1316°C, Ideal for Extreme Pressure and Temperature Conditions 1 x 14g

There is a reason nickel anti seize is used on new O2 sensors. I have experience of Loctite and Bostik nickel products and have found them to be greatly superior to copper anti seize. This appears to be of a similar high quality. Although I cannot rate the long term anti seize qualities, I have found it resists disassembly galling of high temperature parts very well. Had I used copper anti seize, experience tells me I'd have been lucky to get it apart again, even with heating. Despite a high purchase cost, it has already paid for itself.

I've used permatex products before, primarily for brake caliper slide pins and on the side of the pads. This product though was recommended to me as I am using some stainless steel nuts and bolts and this is said to prevent galling of the threads during assembly and any subsequent disassembly. Apparently the Nickel content is what works some magic. The nice thing is that it comes with a brush attached to the lid to help with application. Unfortunately, like all other anti-seize greases, it magically gets on your hands and fingers despite the brush! Seriously though, it works well and I would buy it again in a flash but I think this one jar will go a long way. Excellent product.

Permatex products - through experience these are always a professional / industrial product typically much better performing than similar competition.
