Rigid Tubing

100+ Years of Rigid Tube Bending Expertise

STS Aerospace has over 100 years of rigid tube bending expertise and has evolved in all aspects of precision bending and tube fabrication to become the world leader in aerospace rigid tubes. We excel at working with titanium, CRES, Inconel with diameters ranging from 1/8 to 3 inches and up to 7 feet in centerline lengths. Visit our capabilities pages to see the full portfolio of process offerings that show both processing expertise and continued vertical integration. From simple tubes to manifolds and complex assemblies, we are ready to be your partner in rigid tube fabrication and precision bending.

We Manufacture the Following Types of Rigid Tubes
Rigid Tubing - Simple


Whether simple or complex, we can handle most production sizes, alloys and configurations supporting the commercial, military, space, land and marine industries.

Simple tubes are classified by their diameter (1/8 – 1/2 inches), number of bends, radius, purchased components (ferrules and nuts), materials and end finishing. Our products are tooled for most common diameter and wall thicknesses and we have in-house machine shop capabilities to assist with new tool/fixture design and support.

Rigid Tubing - Complex


With the continued growth of complexity ranges over the years, we have proven our dedication to evolve in line with our customers’ requests, which allows us to continue being the complex rigid tube leader in the aerospace industry.

While complex tube assemblies can range in diameter from 1/4 to 3 inches, we can meet tight tolerances, configure one-to-one bends and manufacture aluminum, titanium and Inconel materials with high, repeatable success.

Rigid Tubing - Fabrication


Our precise fabrication, supported by our extensive experience, has allowed us to create advanced solutions for our customers. We enjoy working side-by-side with you to bring your visions to life.

Fabricated parts are truly our specialty. Working with any materials (Inconel, CRES, titanium and aluminum) and diameters up to 3 inches, we can:

  • Flatten/form tubes
  • Manufacture a tube-in-a-tube, duct assemblies or hydro-form sheet-metal
  • Perform scarf cutting, beading, tube end-forming, laser machining, welding (orbital and manual) and brazing (furnace, induction and torch)
Rigid Tubing - Manifolds & Ducting

Manifolds & Ducting

We deliver reliable parts that meet performance expectations. Our high performing, multi-port fuel manifolds support commercial and military aviation by providing reliability in extreme environments.

Manifold assemblies consist of multiple bent rigid tubes, tees and elbow-type fittings designed to disperse fluid to multiple ports simultaneously. Various high strength / high temperature alloys, from CRES to high temp nickel and titanium, are procured from established quality suppliers. The metal joining process could be weld (machine orbital or manual) or vacuum furnace braze with gold filler material.
