They consist of a body that connects to the tube. It has one compression ring, a ferrule, and a tightening nut. The hermetic union between the tube and the body of the fitting is made thanks to the pressure exerted by both rings on the tube when the nut presses them. The function of one ring is to close it, which prevents leaks, and the role of the other ferrule is to hold the tube.
Extreme conditions? No problem! Our twin ferrule tubing fittings withstand high pressure while being resistant to vibrations even in harsh environments or severe applications. The nuts have an internal anti-seize silver bath as standard.
We stock all sizes and types of REDFLUID fittings, including elbows, reducers, crossovers, tees, valves, sleeves, bushings, welding, etc. In terms of materials, they are manufactured as standard in Stainless 316 / L or in Brass.

The connections with the Redfluid fitting are reliable, all the accessories have been certified with exhaustive tests and the experience since 1984 in the manufacture of accessories supports us. High-quality materials, exacting manufacturing tolerances and unitary quality control contribute to the tightness of Redfluid accessories.
Redfluid twin ferrule fittings for joining tubes have different advantages, they do not twist the pipe during installation or rotate on themselves when installed. The proper design ensures that the load is transmitted axially to the tube and not in a localized area.
The mounting of the accessories is easy thanks to the silver-plated threads, which acts as an effective lubricant and prevent seizure.
