I had a damaged fitting on my oil pan and used the fitting fixer. This was very helpful so I didn’t have to pull the motor and take the oil pan off. It worked fantastic, making a nice new sealing surface on the fitting. It is a very good quality tool and customer service is fantastic. I would recommend purchasing one if you need to do a repair!

Used the -16 Fitting Fixer on 2 aircraft boost pumps where the fitting was part of the main housing that was leaking.
The 37 degree angle cleaned up perfectly and the housing was saved.

I was able to repair the damaged welded in bung on my radiator in about 30 minutes without removing the radiator from the car. I tried the fitting fixer and took the car to the track last weekend. No more leaky connection. Without this tool I would have had to incur the costly process of removing the radiator, having the old fitting cut off and a new one welded on. Highly recommend this product.

This tool worked perfectly. I damaged to An fitting on an oil pan when dropping an engine in a car. This allowed me to repair the fittings from underneath the car without pulling the engine out again! This tool can be a savior!

I used these on my dry sump tank after it was damaged. The fittings came out perfect. Thank you

Great tool and great idea. The only reason I’m giving it 4 stars is because within the first 5 Minutes of using it the threaded insert piece on the guide loosened up and the knurled edges could never bit back properly. Luckily I’m pretty handy ended up tig welding all the threaded inserts on the guides. I would think machining the guide and threaded inserts would be a better approach. But otherwise I was able to fix a bunch of fittings on this old hydraulic animatronic character we are working on so thank you for that.
