PERMANENTS

Permaswage System

Permaswage System Fittings are radial compressed (mechanically attached) onto compatible tubing to provide a permanent joint with metal to metal sealing.

Permaswage System Features

The fitting to tube relationship is affected by differential springback caused by the annealed condition of the connector, relative to the tubing. Fittings contain one (stainless/titanium) or two (aluminum) silicone seals which seals potential leak paths with tube surface defects.

  • Lower weight, minimum envelope, high fatigue strength and cost-effective performance benefits for superior tube connections.
  • Installation tool converts linear force into radial swaging force, resulting in compression of the fitting and tube.
  • Fast, reliable repair and production of aircraft hydraulic, fuel, pneumatic and ECS tubing lines.

Permaswage System

Fittings

  • Provides optimum flexure performance.
  • Controlled dimensions with wide tube insertion tolerance to compensate for structural tolerance build up.
  • Leakproof joints for the lifetime of the aircraft.
  • Simple inspection.
  • Simple tube preparation.
  • Comes in all configurations including, but not limited to, straights, elbows, tees, crosses, reducers, flanges, and more.
  • Permanent connections can interface with lipseal, flareless and flared couplings
  • Available in corrosion resistant steel, aluminum and titanium materials.

Tooling

  • Design features allow for simple, one-hand operation.
  • Lightweight and portable.
  • Allows for use in tight tube clusters.
  • Rapid “in situ” and “on the bench” installation.
  • Repeatable, consistent process.
  • Tool kits are available in a variety of sizes and in a variety of size combinations
  • Tooling training in-the-field is available.
  • Tool maintenance program is available to service tooling.
