Just not to brag but this tool made my job removal and installing the cups on my 2002 f250 a brease! I would not recommend using any other product. This tool is a must to install the cups correctly in you ride.

Loctite 620 is the only product I would use for injector cup retaining.

I ended up also using loctite 7649 as a primer since i was doing the job at low temps and the cure speed is unacceptably slow.

Loctite 620 perfect for the job.. I tried a different brand before. I had to do the job twice. Now with the 620 I haven't had no problems

Doesn't make sense that you can't find Loctite 620 at local stores. Thank God for Riffraff Diesel. They make it easy to get.

I ordered this injector sleeve compound it shipped fast and riffraff diesel is one of the best places to get hard to find items like this compound works great thanks riffraff diesel.....

So far so good! after flushing the system a dozen time getting the diesel out of the system. dont see any new signs of fuel...so Im happy

plenty of product to do full set plus.
so far no leaks so I am happy.

I've dealt with Loctite products for years in different diesel applications and from those past experiences, I would recommend this product. I wouldn't chance a "off" brand where this stuff is going in the head to seal and hold!!!
