Post-Sales Follow-Up (July 30, 2021) Stainless Washers for ValvesYes, everything is fine. Thank you for asking. I hope everything is well with you also. The washers are working good, It will take me some time to go through that many because orders have been slow for the valves that they are used with. I am only using about 100 per month right now. Best Regards, Jim
