Includes: one Fupa 12 Pyrex cup (a part of FU12KC), one Fupa 12 Ceramic cup (a part of FU12KOKN), three diffusers, four O-rings and one titanium cover for the Pyrex model.
The Fupa 12 models are constructed with the identical original diffuser as the Jazzy cups but in larger packages. Fupa 12 cups are recommended for Mild Steel, Stainless Steel, Chromoly, Titanium, Inconel and other space grade applications. The Pyrex model will work best on thinner applications such as header tubes and chassis tubing. The Ceramic cup performs identically to its glass cousin but is made with the added strength that ceramic cups can bring.
The Fupa 12 Pyrex cup is for use with DC only up to 175 amps whilst the Fupa 12 Ceramic cup is also DC only with an increased amperage rating of 200.
