cleaners and inhibitors. Chapter 9: Fluid Lines & Fittings Introduction Aircraft fluid lines are usually made of metal tubing or flexible hose. Metal tubing (also called rigid fluid lines) is used in stationary applications and where long, relatively straight runs ... made simply by replacing the tubing. However, if replacements are not available, the needed parts may have to be fabricated. Replacement tubing should be of the same size and material as the original tubing. All tubing is pressure tested prior…
- Chapter 9: Fluid Lines & Fittings › Swaged Fittings
Special installation tooling is available in portable kits. Always use the manufacturer’s instructions to install swaged fittings. Typical Permaswage™ fittings are shown in Figure 9-25. One of the latest developments is the Permalite™ fitting. Permalite™ is a tube ... fitting that is mechanically attached to the tube by axial swaging. Permalite™ works by deforming the fitting into the tube being joined by moving a ring, a component of the Permalite™ fitting, axially along the fitting length using a Permaswage…

fitting that passes through the bulkhead is longer than the other end(s), which allows a locknut to be installed, securing the fitting to the bulkhead. Fittings attach one piece of tubing to another or to system units. There ... four types: (1) bead and clamp, (2) flared fittings, (3) flareless fittings, and (4) permanent fittings (Permaswage™, Permalite™, and Cyrofit™). The amount of pressure that the system carries and the material used are usually the deciding factors in selecting…
