Double Ferrule Fittings

Swagelok offers a wide range of double ferrule compression fittings.

Double ferrule fittings. Furthermore our double ferrule tube fittings meet or even exceed nuclear industry requirements for quality and documentation and they meet key standards including asme section iii and b16 34. Widely used in instrumentation and process tubing systems these fittings have a front ferrule that act as the sealing while back ferrule grips the tube. All the action in the fitting is by an axial movement along the tube instead of a rotary motion to create the joint. This is because they are easily installed keeping downtime to an absolute minimum.

Stainless steel is widely known as inox steel that has been used in various industrial applications. When the fitting nut is screwed on the tube the ferrules get deformed to create a tight seal. What are double ferrule instrumentation fittings. Double ferrule compression fittings are favored when installations need to be disassembled once in a while.

Available in numerous configurations and sizes our double ferrule compression fittings are made up of four parts consisting of a body. These fittings help in enabling leak tight connections due to its strong mechanical grip and other properties. And finally apart from the vacuum tubing fittings we offer valves tubing and instrumentation as well as tailor made solutions for any specific issue. Double ferrule fittings are available in many materials but stainless steel has been widely used by the industries due to its highly unmatched specifications and properties.

Double ferrule fittings comprising of back and front ferrule with axial motion in the pipeline arrangements ensure a leak proof and torque free connection. For example parker double ferrule fittings are also available in steel and a few different corrosion resistant alloys including 6mo alloy 825 and alloy c 276. When the nut is tightened the ferrule impresses on the tube to make a leak proof connection. Parker double ferrule tube fittings are designed as leak free connections for process instrumentation applications.

Double ferrule fittings work on the proven principle of ferrules swaging to the tube when tightened with a spanner. Double ferrule fittings by comparison are usually available in a wider variety of materials along with stainless steel and brass. Furthermore they can be re used keeping the cost of materials as low as possible. Parker double ferrule tube fittings are available as standard in heat code traceable 316 stainless steel.

Double ferrule compression fittings feature an outer nut two deformable ferrules in soft alloy or non ferrous metals and a tube fitting body and are available for metric and fractional tube sizes. They are regularly used in process measurement and control systems in aerospace defense chemical processing plants medical equipment and oil gas industries. The double ferrule tube fittings are manufactured to the highest quality standards and are available in a broad range of sizes materials and configurations.
