If you own an E4 Series RDE tip purchased before 2006, you must choose one of the special "thin disk inserts" from the pricing table. If you purchased your E4 Series RDE tip after 2005, then you may use any of the standard 5.0 mm OD x 4.0 mm thick disk inserts in the pricing table.
Disk inserts with diameters larger than 5.0 mm may require the use of stainless steel or epoxy encapsulation for additional support.
