The Fupa 12 Ceramic kit includes 2 ceramic cups and a spare diffuser . It performs identical to the original glass version but has the added strength ceramic cups bring. The ceramic version comes only in 3/32 – 2.4 mm tungsten size and will thread on a 45V44 or the 17 Kit . It does not require Orings
The Fupa 12 will handle up to 200 amps non continuance . And it is recommended for DC only applications

NOTE: the Diffusers in the cups are designed to work only with the Furickcup brand cups. We also recommend you buy a few spare diffusers to have, they are somewhat consumables and will eventually need to be replaced, The diffussers must be installed like you received them installed and must seal tightly around the cup or you will have poor results. They are designed to have a gap between the 2 layers of screens and it is recommended you install them back that way, It may take a few tries to get the screens in properly but have patience , The cupped side goes in first .
