These standard dispensing needles are made out of stainless steel cannula and a polypropylene hub. They are anti-static and non sterile and have a blunt open end. These are the classic "dispensing" needles used for years by companies large and small. Only 32 RW needles include covers. Vita can also quote bent stainless cannula ½" and longer, if required.
PTFE Lined Needles Ideal for adhesives and epoxies that typically clog other needles, microdot applications, low viscosity fluids 304SS Cannula lined with PTFE Insert Polypropylene luer lock hub Greater rigidity compared to standard PTFE needles due to stainless steel outer cannula
Commercial tubing & pipe are produced in both the seamless and welded process. Seamless starts with forged hollow bar while welded (also known as "as-welded", "sunk" or "CDOD Tubing") starts with flat strip stock. The seamless process accommodates very heavy wall or high pressure applications but is expensive and tends to have concentricity variances. As-welded tube will have the residual weld bead of metal protruding into the ID of the tubing. The ID will be rough since the material is not drawn over a mandrel.
Vita Needle offers stainless steel wire in several medical grades and tempers. Typically sold in hard temper, SS 302 wire is our most common alloy. Chemically, it is the same as SS 304 except for a higher carbon content, which effectively gives it a higher tensile strength for a given amount of cold work. We also stock hundreds of sizes of 304, 316 and 316 LVM wire. Other alloys are also available upon request and special sizes can be custom made if not available in stock.
Shaped tubing refers to tubing that is not round (circular) in form. Frequently, applications involve some type of stainless steel support for a product, a path or race for fiberoptics or other smaller components, or a dispensing application. Depending on requirements detailed by the customer, shaped tubing can be made stronger in some directions in a similar manner to the concept of an I-beam. All tubing drawn into shapes has to be formed through custom manufactured dies and subsequently straightened though specially formed tooling for straightening profiled tubing. In some cases, customer requirements result in a modest engineering fee for the design work associated with developing a method to form the tube. Vita Needle supplies shaped tubing in a variety of alloys, most popularly in 304 or 316 stainless steel. However, all alloys that Vita Needle produces can be drawn into shapes provided the shape is capable of being formed.

Our polypropylene syringes are designed for industrial dispensing for careful placement of materials such as adhesives, pastes, sealants, lubricants, fluxes and grease, among others. Manual versions are pre-lubricated and include the syringe barrel, plunger and stopper. Syringe stoppers are made of natural black medical grade rubber or polyethylene. Air operated versions are intended for use with dispensing machines; they do not include the plunger and are not lubricated. All items are non-sterile.
Vita Needle utilizes Electrical Discharge Machining, otherwise known as EDM or spark machining, as one method to fabricate burr free cut to length tube parts. In addition to cut and deburred tubes, Vita relies on EDM to fabricate features on tubes, ranging from simple slots and angled cuts to holes, patterns, contours, skives, complex shapes and other unique geometries. Fabricating tubing using EDM is a CNC process. A program is generated which drives the wire (or sinker electrode) along the designated tool path, and the resulting high frequency electrical discharges between the workpiece and the electrode erodes the specified path.
Swaging is a cold forming operation used to reduce the outside and inside diameter of a tube. It is useful for medical, industrial and aerospace applications (such as landing gear tubes and aircraft instrumentation) where a diameter reduction is required but a multi piece assembly is not desired or is too expensive.
Certain applications demand seamless stainless steel tubing for critical functions. Often, seamless tubing is required for petrochemical, gas or nuclear applications where high pressures and exposure to corrosive environments are the norm, or if the tube's wall is too thick to be rolled and welded. Seamless tubing is manufactured by repeatedly drawing a forged hollow bar through a series of smaller dies. No welding takes place at all during the process, avoiding microscopic changes in the grain structure of the tube. Vita's unique tooling and setup capabilities allow us to produce small runs of stainless small diameter seamless tube in a matter of a few weeks, not several months. We also offer competitive pricing on larger quantity seamless tube if required. Coils, straight lengths or fully finished fabricated parts are all within Vita's capabilities for seamless tubing. The majority of Vita's seamless tubing is custom made, except for standard commercial grade sizes which can be found on our commercial tubing page. Additionally, Vita stocks millions of feet of standard and non standard welded and drawn sizes, if this method is acceptable for your application.
Polypropylene Needles Polypropylene cannula and hub Luer Lock Hub Ideal for cyanoacrylates and adhesives that clog easily Less likely to scratch sensitive surfaces than stainless steel tips End user can easily cut to shorter length if required with scissors, knife or other means Environmentally friendly alternative to PTFE
A skive is a slice along the long axis of a tube or wire that leaves a thin layer of tubing (or wire) remaining after completion. Typically as the end of the desired cut length is approached, the skive gradually rejoins the remaining tube over a large radius transition zone. The image below depicts a skived stainless steel tube. They are popular for balloon delivery and retraction applications, and can also be found on tubes for the purposes of product alignment with another piece, or to bottom out a product for secondary welding. Vita has a proprietary method to produce skives with close tolerance requirements, and can even break the heels and radius the tips of skives if required for the application. Finishes along the cut surface of the skive can also be improved using our proprietary manufacturing methods.

Medical hypodermic needles (or needle assemblies) typically consist of a machined fitting joined to a fabricated tube. Most often, the tube is stainless steel and pointed or blunt (click on cannula link for more details). The worldwide hypodermic needle fitting standard in the medical, laboratory and dispensing fields is the female Luer Lock. The mating part, which provides a tight seal via a quarter-turn, quick-disconnect is the male Luer Lock.
The Luer lock system of joining needles to syringes has been in use for generations. Growing from the original application of a metal fitting attached to a glass syringe, male Luer Lock adapters allow this connection system to be used in a myriad of applications. Vita Needle Company has proprietary technology which permits plated brass adapters to be produced far more economically than conventional, single point machining. Because the Luer Lock system specifications are so demanding, very few producers without the generations of Vita's experience are willing to manufacture and stock these luer lock adapters. Vita's variety of stock brass and stainless steel, ANSI and ISO 5941 and ISO 80369-7 TAPER ONLY compliant luer adapters and thread to thread industrial adapters supplements our ability to manufacture to custom specifications.
Vita Needle cuts and deburrs tubing to customer specified lengths and tolerances utilizing several methods. Our most frequently used cut and deburr methods include: Abrasive: Relies upon a spinning cutoff wheel, typically aluminum oxide, to cut tube and a secondary deburring process is utilized after cutting is complete. Electrochemical (EC or ECM): In simple terms, a combination of abrasive and reverse plating by incorporating electrical current into the process in order to cut and deburr tube simultaneously. Electrical Discharge Machining (EDM): Electrical current creates a series of high frequency discharges that erode tubing material in a burr free manner. Supported shear: Custom dies and related mechanical supports are used to precisely cut tube free of burrs.

Rotary swaged to a minimal flat then sharpened and polished. Limitations on sizes apply. Certain geometries may require custom tooling to be made and generate a modest engineering charge. Often, customers specify a hole or slot near the tip to permit liquid or gas passage.
The majority of stainless steel tubing and wire sold by Vita Needle Company falls in the 300 series stainless steel family. The composition of the stainless steel tubing varies depending on the alloy, but in general stainless can be an effective solution for many different types of applications. The key element in stainless steel is chromium, which when alloyed with the remaining elements, permits formation of a microscopically thin, passive layer on the surface of the metal which resists oxidation (rusting). This invisible layer is consistently self repairing in a normal environment---in other words, if the tubing surface is damaged, the layer reforms to protect the underlying tubing from oxidation. The condition of this layer on the surface of the tubing can be enhanced by a process known as passivation, which removes free iron and contaminants from the surface of tubing that might otherwise limit or reduce the formation of the passive layer. However, under exposure to certain environments, the self-repairing nature of the passive layer can be reduced, depending on the alloy and external factors.
Welded and drawn is the preferred tubing choice in terms of economy, lead time and tolerancing compared to seamless in most instances. Many demanding applications call for the T.I.G. welded and plug (mandrel) drawn method, used by Vita Needle for over 85 years!
