Designed for applications that require no leaks at pressures at or above 20,000 psi, Tri-Fitt Kit includes black carbon-PEEK ferrule, stainless steel triangular ferrule, and stainless steel nut. Carbon PEEK ferrule deforms when stainless steel nut is tightened and stainless steel triangular ferrule clamps onto tubing at same time to increase sealing pressure. Both stainless steel parts are reusable, while carbon PEEK ferrule must be replaced when fitting is removed or loosened.
