Does anyone know where you can buy the brass tube seats found in the ports of your master cylinder, brake calipers, and distribution block?

I am rebuilding my distribution block with a kit from Muscle Car Research and it seems my distribution block has an oddball size seat. The seat you have to pull out in order to get the springs and piston out. The pressed in part of the seat I pulled out of my block is 13/32 inch in diameter. The replacement seat from the kit is 3/8 inch in diameter. It's only 1/32 inch but it makes all the difference in the world as far as the press fit

I called Scott at Muscle Car Research and to this point, he hasn't come across a block that his 3/8 inch replacement hasn't worked in. He does not stock the size I need. Interestingly enough, I have another distribution block here identical to mine. I bought it off of Ebay to get the switch terminal off of it (I broke mine) and the bore in it is smaller than mine and the 3/8 seat would work in that one.

I have looked online and checked with NAPA and other auto parts stores and turned up nothing. When I show it to the guys at the auto parts stores and the look at it like it's something that came from another planet.

Any suggestions ???

Thanks.......Dave

I would take that to mean my chances of finding someplace to buy these from is slim?:smile2:

What I don't understand that if they are still making master cylinders, brake calipers, and other brake system parts that use these seats.......where are these manufacturers getting them from?Someone is making them. Maybe they make their own. Same thing with companies who rebuild these parts. I wonder where they get them from?

I would visit your local hydraulics/pneumatic vendor making tubing and hoses and ask for SAE flare copper crush washers, SAE = 45°
Best sealing device since sliced bread.

I looked at the crush washers online to see what they looked like. Am I correct in assuming that you would place one of these washers over a worn or deformed brass seat then the copper crushes between the brass seat and the flare of your brake line making a tight seal?.......or am I way off?

Correct, thus the reason they call them crush washers - soft copper forms to the irregularities of the mating surfaces.
