We work hard in trying to assist our customers when they have another vendor discontinue an item.  In this case we were told that a customer was no longer able to obtain a specific 18mm septa which we were thankfully able to add to our catalog at a substantial discount to their previous source.

18mm Silicone/PTFE Liners; PN 10709

We encourage customers to contact us with any product request whether taking up backorders/discontinued items or new product engineering projects!
