Design and Assembly Services

Swagelok design and assembly services

Take the Building and Testing of Fluid System Assemblies Off Your To-Do List

If you’re short on manpower, Swagelok can provide an extra set of hands by fabricating your fluid system assemblies for you. We produce a professional, repeatable solution, with testing, inspection, and packaging included—all covered by Swagelok’s Limited Lifetime Warranty.

We call these assemblies Swagelok® Custom Solutions. Custom Solutions can be small or large assemblies, consisting of a few components or a complete panel or enclosure. They are built with Swagelok’s own high-quality fluid system components, but we can also incorporate wiring, automation, transmitters, relays, pumps, and more. Whatever your parameters, rest assured that you’ll receive only the highest-quality assemblies, panels, or enclosures from Swagelok.

Save Time With Standard and Configurable Assemblies

Swagelok design, fabrication, and assembly experts have worked with businesses across the globe to add efficiency and reliability to their operations by delivering reliably designed and constructed fluid system assemblies. Standard assemblies we’ve developed include:

Swagelok Grab Sampling System

Grab Sampling Systems

Customizing Swagelok® grab sampling systems allows for safe, efficient sample capture while meeting your specific plant application needs. The panels are available in a variety of configurations and advanced features.

Mechanical seal support system

Mechanical Seal Support Systems

Swagelok® seal support systems are guided by API 682 and are offered as kits and assemblies. These systems reliably supply either gas or liquid to the mechanical seal to regulate the environment in which the seal operates, increasing longevity.

Swagelok gas distribution program

Gas Distribution Systems

We evaluate existing gas distribution systems and build standardized, configurable gas delivery systems to help protect system operators, increase process uptime, and improve process accuracy and repeatability.

Swagelok Analytical subsystem

Analytical Subsystems (PrESS)

Pre-engineered and preassembled fluid sampling and control subsystems, such as fast loops, field stations, calibration and switching modules, sample probes, and fluid distribution headers, bring efficiency and consistency to your operations. Swagelok®  pre-engineered subsystems (PrESS) minimize system footprints, simplify system design, and promote representative samples and accurate analytical results.

Case Study: Fluid System Evaluation Leads to Production Continuity for Manufacturer


Manufacturing company. “How do we discover leaks early to avoid scrapping assemblies?”


A company was forced to scrap $12,000 worth of assemblies because leaks were discovered too late in production, leading to loss of revenue and reputation with customers.


Assistance finding the reason for the leaks, improving quality assurance, streamlining production processes, and eliminating product and labor waste.


  • Swagelok field engineers identified the root cause of the assembly leaks was due to intermix/interchange of fittings
  • Leak-tight, fabricated subassemblies were provided through Swagelok’s Custom Solutions program


  • The company avoided a two-month backlog in production that would have resulted in 100 fewer units being manufactured, equaling $800,000–$900,000 in losses
