Repair Leaky Fittings on Tanks: 5 Real-World Examples

posted in: Hard Line Sealing | 4

The ability to repair leaky fittings that are attached or welded to a tank is invaluable.

Brand new to the industry is Fitting Fixer—an inverted 37° cone that’s coated with diamond dust. Fitting Fixer repairs scratches, dings, imperfections, and other unimaginable damage, leaving an optimal sealing surface.

Below are five examples where people were able to repair a leaky fitting on their tank or pump and avoided the headache of having to replace the attached fitting:

1. Leaky Fitting on Radiator

This example is the most common. There was an imperfection on the fitting’s surface that was preventing a good seal. This usually occurs from over tightening.

Rick Milanazzo used our 3/4″ Fitting Fixer tool to repair the imperfection on the fitting that was causing the leak.

“I repaired the damaged welded in bung on my radiator in about 30 minutes without removing it from the car. After using the Fitting Fixer, I took my car to the track and there was no more leaking. 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. I highly recommend this product.”

2. Damaged Fittings on Aircraft Boost Pumps

This example comes from the aircraft industry. The fittings on an aircraft boost pump were leaking due to imperfections.

Mark Aney used our 1″ Fitting Fixer to repair the surface on all the fittings.

“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.”

3. Damaged and Painted Over Fittings

This example is not the most common occurrence you’re going to find, but it illustrates just what could happen and what’s possible with Fitting Fixer.

Dave Bris sent his tank out to be powder coated only to get it back with one of the fittings covered in paint and two with damage from a tool that was used to remove the paint. Turns out the powder coating guy didn’t cover the fittings before he painted the tank.

Dave used our 3/4″ Fitting Fixer tool to resurface all three of the fittings on his tank.

4. Gouged Fitting on Aftercooler

Here’s a prime example of how the sealing surface on a fitting can get ruined. Andrew Chau had a nasty gouge on one of the welded-in fittings on the aftercooler for a supercharger.

“The gouge in the fitting came from a cheap fitting which had an imperfection on the thread. When I threaded the fitting on, it must have dislodged some aluminum and when the fitting tightened onto the seat, it gouged the finish.”

Andrew used our 3/4″ Fitting Fixer to resurface the fitting and bought a new female fitting for a leak-free connection.

5. Dented Fitting on Oil Pan

Last but not least is the case of the dropped oil pan. This mishap left a dent at the end of the sealing area of the fitting. A little extra work was necessary for this repair, but certainly less than what the alternative would have been.

Brad Shamo used our 3/4″ Fitting Fixer to resurface the fitting’s sealing area.

 

“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!”

      On the before pic he has the aftercooler out and on the after it is installed so it’s not the same angle. Maybe he couldn’t get a good shot from the opposite side. It was the only picture we got from him and it’s hard for us to ask more from people when they are documenting this for us. We are happy that they do it at all.
