Del Fitting Seal 3/8 OD Aluminum

These seals are amazing! Instead of replacing lines and fittings in a very tight engine space, these sealed the damaged AN fittings perfectly.

Fast service as always! You and mcmaster carr are the best

Works perfectly

A little oil leak goes a long way down the belly of an airplane. This little seal stopped the leak and gave me a little more piece of mind about my oil pressure situation.

Fantastic product. My guys use these in the US Air Force. We decided to try on our civilian GE LM6000 engine and they worked great. Prevented having to spend several thousand dollars for a new GE part.

If you are working with AN fittings I agree you should have some of these in hand. I was doing an efi conversion in a car and two expensive 90 degree fittings were leaking. Ordered these and some extras, I put it in the fitting, connected it all and that was the end to those pesky leaks. Highly recommend them.

These worked great, had several leaks in my newly installed brake system. Lost one star for packaging, these are super soft aluminum and need to be packed in a container. Found that by carefully forming it over a loose but same size male AN fitting easily got them back to perfect fit. DO NOT OVERTORQUE these, they are very soft and will tear if overtorqued.

worked as advertised. Stopped small fuel leak immediately

Ordered these for replacement on AN fittings after fuel system repair. They are extremely fragile and I was unable to get one into proper position without damaging it. Finally put the system together without the fittings and it worked fine, no leaks.
