Do replacement 19 mm master cylinders use the same two small metal rings inside the fluid inlet ports

Do replacement 19 mm master cylinders use the same two small metal rings inside the fluid inlet ports from the reservoir. I have discarded my old cylinder and the neew one does not have the small metal washers under the rubber
grommets.

I am not 100% sure.

I opened a post in our forums. A Pelican community member may be able to answer your question.

I would grab a repair manual. It will list the special tools and Or you can give our parts specialists a call: 1-888-280-7799, They will help you find what you need.

If your old one had them I would find some.

I recently installed a new ATE 19mm purchased from Pelican. It came with the two washers in the box with the master cylinder but in a separate baggie. The rubber grommets were installed, so they had to be pulled out and the washers put in.

Yes, they are required to allow the metal tube to seat itself. The flared end of the tube sits on the washer and is sandwiched by the grommet. Otherwise the flared end will go in too far, and float; perhaps not sealing. The washer ensures the tube will flow freely under gravity.
