Custom Stainless Steel Tubing Fabrication

From straightforward cut and deburred tubes to complex medical devices or industrial parts, Vita has the capabilities and services to fabricate parts to your specifications.

Some examples of our work include cardiac surgical instruments, components for military rifles, veterinary implants, fiberoptic sheaths and sampling needles installed on a space probe now on Mars. We can produce specialty fittings and EDM or CNC / hand machine parts quickly and to your specs. Tube forming, tube swaging, assembly, and special finishes are easily handled by Vita. Most of our work is with stainless/high nickel series, brass, aluminum and copper but we also work with other alloys.

Custom Tubing Capabilties

Our millions of feet of many sizes of tubing gives us a unique advantage and our drawing and sizing capabilities allow us to form just a few feet or hundreds of thousands of feet. Vita Needle's equipment, technology, five family generations of experience and partnerships with other American family owned businesses allow us to offer complete manufacturing solutions. In short, our customers optimize value without having to worry about quality or delivery of their parts.

Closed End Consistent Wall

Formed and hermetically sealed spherical end. The wall thickness is consistent throughout the dome, ideal for temperature probes and other instrumentation applications. Most cannula are requested in 304SS, but we also stock additional 300 series stainless, nickel, copper, and brass alloy tubing.

Slot & Holes

Cannula side ports typically allow for the transfer of liquid or gas. Electrical Discharge Machining (EDM) can form simple holes and slots to complex shapes, unique patterns and geometries.

Pencil Point

Manufactured by swaging the tube, hand sharpening the point if necessary. Pencil points puncture without coring.

Finishing

Vita Needle can offer a variety of finishing options, including plating, passivation to reduce surface contamination, electropolishing for an improved finish, laser marking, and grit blasting, often for a rough surface used for plastic over molding, among others.

Machined Fitting

Vita Needle stocks a wide variety of luer lock, NPT, barb and thread fittings, and can custom manufacture fittings. Most stock fittings are offered in brass, which is more easily machined than stainless, with nickel plating. Nickel plating has replaced less environmentally friendly chrome plating as the standard for the medical industry.

Bend

Vita Needle can engineer and build tooling to create bent tubes, within gauge and radius limitations.

Assembly Capabilities

Include laser welding and brazing. Soldering and brazing utilize filler material to join custom fabricated parts, while welding fuses parent materials by using heat and sometimes pressure.

Flare

Typically functions as a transition, guide or stopper. As a general rule, a flare diameter of approximately 20% of the OD is the maximum that can be achieved, but wall thickness and other factors can be additionally prohibitive.
