Cleanliness Chain

When it comes to semiconductor manufacturing, you need to know that every supplier process, from raw materials selection to final inspection of installed components, is designed to get you from source to exhaust with maximum cleanliness and no contamination.

Cleanliness Chain

How Are We Different?

Cleanliness starts with our commitment to ultrahigh-purity materials, followed by our manufacturing processes, cleaning specifications, and quality control procedures. With these tools, you can trust Swagelok to provide the products you need so you can manufacture products with confidence.

Where Do You Want to Go?

The path to success just got shorter. Swagelok high-purity and ultrahigh-purity offerings help ensure clean manufacturing. Not only do we have the products, but we provide customized solutions too. We consider your operating environment and account for factors such as corrosiveness, the need for repeatability and throughput, and eliminating contamination. Innovations like our ALD valves enhance manufacturing efficiency of semiconductor components. Swagelok’s ongoing commitment to quality ensures speed, consistency, and cleanliness.




Semiconductor manufacturing cleanroomWhen it comes to semiconductor manufacturing, you know best what you need. High yield and throughput. Maximum cleanliness and reliability. Swagelok helps you get there with our innovative products, manufactured to the highest standards of cleanliness and customizable for your application.

  • Smooth internal surface finish reduces the risk of particle entrapment and material contamination
  • Innovative designs promote fewer areas for entrapment, rapid purging, and less stress in high-cycle applications

We don’t stop there, though. We back our products with support for your high- and ultrahigh-purity applications, from fabrication to finished product.

From Idea to Installation

How do you make a great product even better? When you customize it to meet your exact requirements.

Swagelok Engineered-to-Order Products

We know our products, and we know what they can do for you. Swagelok design experts help you customize our products to meet the demands of your application, then we build it, test it, ship it, and warranty it.

Swagelok tube fitting teeMaterial Options

Swagelok materials of construction are backed by science. They’re formulated, tested, and proven for high-purity applications like semiconductor manufacturing. From the bar stock to the fluoropolymers, the properties of each of these materials help you to achieve the results you need. Swagelok chooses materials carefully for the manufacturing process, so you can be assured of materials that allow easy welding and installation, while providing you with the purity your application requires.


Swagelok components are manufactured to ensure consistent quality, ultrahigh purity, corrosion resistance, and weldability. What begins with material selection is carried out in our stringent and highly controlled manufacturing processes, which include surface processing to help enhance corrosion resistance and minimize contamination by removing surface imperfections.

Swagelok materials are electropolished and finished with passivation.


Electropolishing is essential for creating a smooth inner surface for tubing to be used in gas distribution systems. Electropolishing is an electrochemical process that strips away metallic impurities and smooths imperfections, leaving a much cleaner surface. This process is superior for semiconductor applications as the potential for embedded abrasives left in the surface does not exist as with mechanical polishing.


Passivation further cleans the surface and promotes the material’s corrosion resistance by creating a chromium-rich passive oxide layer.

Cleaning and Packaging

We stand behind our product offerings with our commitment to ultrahigh-purity manufacturing. We understand the UHP industry’s unique requirements for cleanliness, so we can help you meet or exceed industry standards.

Swagelok atomic layer deposition (ALD) valveThroughput and Repeatability

Throughput means you get more material through your manufacturing system faster, with less downtime. Repeatability means that the product you produce is the same, every time. With Swagelok, you get these benefits and more when you select products based on their suitability for your high-purity application. Innovations like our ALD valve enhance semiconductor manufacturing efficiency.

  • Cobalt-based super alloy (UNS R30003) material for strength and corrosion resistance
  • Optimized, patent-pending design for ultrahigh cycle life
  • High-speed and repeatable actuation
  • Suitable for thermal immersion operations
  • Capable of valve opening or closing time of less than 5 ms

Quality, Reliability, and Safety

Swagelok’s ongoing commitment to quality and reliability ensures our products last a long time, so you replace them less frequently. Our verification processes confirm the suitability of our products for use in the harsh extremes of the semiconductor industry—so you and your processes stay protected.

Installation training for the semiconductor industryInstallation Training

How to bring your quest for cleanliness full circle? With complete installation training from Swagelok. In ultrahigh-purity manufacturing, system components must work together to maintain leak-tight seals on toxic, corrosive fluids and gases while maintaining system integrity and purity under a wide range of operating conditions. Understanding how to optimize performance of Swagelok products with training in proper installation helps you meet your manufacturing goals and ensures your processes and personnel operate safely.
