Source for 1-piece gasket for HMV No.4 ?

To the guys using the white Exhibition tubing, are you splitting it down the seam so that the mica can be inserted in it?

The perfect replacement is 2 mm silicone medical tubing. It offers gentle clamping pressure as the original gasket did, But you need to glue it onto the diaphragm before installation, or install a diaphragm of the diameter 2-3/16 inch to compensate for the smaller diameter gasketing. I had considered having these gaskets made, but the set up cost for manufacturing made it prohibitive, especially since the amount of people that would actually purchase a gasket for five dollars, or four dollars, wouldn't make up for the set up cost. Those red rubber washers being sold on the Internet don't work, the hard ones, or the soft ones. If they did people would be raving about them, including me

I wonder of something like this would be easier for you to work with? http://www.ebay.com/itm/50-pcs-white-O- ... g-Fi-7yjVg

No, using one tube on each side.
