I am looking for about 20’-25’ of a gasket material about 1" wide by 3/4" height. Any suggestions on where I can get this? It has to be rubber.
try mcmaster.com
Any suggestions on what type of material it should be? This is for a blast cabinet so it has to be able to hold up.
urethane is pretty abrasion resistant.
Does it compress at all without much force? It doesn’t really have to be that abrasion resistant it is for the seal between the lid and the base. I outlined the part.(very poorly) 
This is when it’s shut:
try a nitrile rubber
cool, thanks.
i usually get stuff like that from Sealing Devices.
