Fixed my compressor!
This tiny little part made the whole compressor useless. A simple replacement with plenty of walkthroughs on YouTube got me back in business.

The fit was very tight which was great.
The part was a nice tight fit. I tried to be careful not to damage the gaskets because the top gasket is very pricey. I ended up replacing both gaskets any way.

Parts Used
The top portion of the Porter-Cable compressor is somewhat difficult to access. There are two screws that keep the upper assembly intact. Once removed the top part slides about 1" and then there are 4 screws that hold the upper pieces (2) together. The compressor head must be removed taking care not to damage the gasket. The tube seal has a seat in which it sets. Push the seal over the tube, insert the seal in its place and put the head back on the compressor.
To make it easier, I removed the clamp that held the rubber hose going into the tank and replaced the clamp with a screw type. It offered a lot of movement that had been restricted.
There are a number of rubber bumpers that protect the components. They are easily knocked off. Take note of where they belong and ensure all are in place before reassembly.

Removed the screws holding the two half''s of the compressor and removing the hose clamps. Then remove the old tub seal and install the new tub seal. Put it all back together. It works just fine and no more air leaks.

I found your YouTube video on how to replace the seal. It is a excellent video and very informative. I followed it and had my compressor working with no air leaks. Here is a copy of the link. I hope it will help some others with the same problem.

Access to one of the torx screws holding the cover together

Difficulty

Time
30-60 minutes
Tools Used
Screwdriver, Socket set, Extra-long neck torx screwdriver
I had to 'make' a long torx screwdriver to access one of the screws holding the top plastic housing halves together. I used a piece of brass bar, bored a hole in one end to receive a torx bit of the right size and then used a vice to squeeze the sides of the bored area to hold the torx bit in place in order to disassemble then reassemble the plastic housing. (I also used plumber's putty to make sure the bit did not fall out.) It would have been good to have known what size and length screw driver to have before beginning the repair. Everything else was straight-forward.

Air Leak above 60 psi
David - February 23, 2018

Compressor
Difficulty
Easy
Time
30-60 minutes
Tools Used
Screwdriver, Socket set, Torx Drivers
Disassembled compressor cylinder, replaced tube seal, gaskets and valve plate, reassembled. There was a YouTube video from eReplacementParts available if necessary. Some of the screws in the housing were in deep pockets and required torx driver with long shafts, but otherwise simple and straightforward. The location of the air leak at the tube seal was easy to diagnose once the housing was disassembled, by pressurizing and listening for the leak. Over time, heat will degrade the seal, fairly common problem for this compressor.

Put new seal in a cup of HOT water for a couple minutes (to soften it, makes it way easier).
Slid seal over pipe
Put seal into cylinder head.
Reinstalled head, motor, covers, compressor to tank.
Would suggest ordering head gasket at the same time, I saved mine, but I have a lot of experience with engines and gaskets.
