Ferrule Tube Fitting | Swagelok Double Ferrule Stainless Steel Fittings Thailand

Ferrule Tube Fitting (Swagelok Double Ferrule Tube Fitting)

Swagelok ferrule tube fittings, also known as Double Ferrule Tube Fittings, are precision-engineered stainless steel fittings designed to provide reliable tube grip and leak-tight sealing. Each fitting consists of two ferrules, with distinct functions to ensure safety and performance in fluid and gas systems.

  • Front Ferrule: Provides strong tube grip to secure the tubing and reduce vibration.

  • Back Ferrule: Creates a leak-tight seal to prevent fluid or gas leakage.

The most critical factor in using ferrule tube fittings is proper installation. Swagelok tube fittings must be tightened to the specified number of turns according to installation standards. When correctly assembled, the fitting forms a mechanical seal, delivering high sealing integrity, enhanced safety, and effective tube retention to prevent tube blowout.
