Get a can of dry teflon (PTFE) lubricant from Home Depot. Do NOT get Liquid Wrench brand (takes too damn long to dry). Spray the felt seal thoroughly, and I spray the base plate with a little too. Respray the felt every so often.
there is a few things you can do..get a few extras and have them soaking in a tupperware container filled with 30 weight oil and every so often rotate them out..this will keep them lasting longer....or you can get a zoom spout oiler and put some on the felt ring every so often....
not real sure what is going on with the felt rings for the RX...the old ones use to be harder and last a long time..the newer ones are now really soft and do not like to seat into the ring....I guess they figured if they cant sell the RX like they use to..they had to come up with some other way of getting our money.........
