Custom fabrication for hard-to-source vacuum components

Vacuum systems rarely fail because one generic part is missing. They fail because a flange is damaged, a feedthrough is obsolete, a cold trap no longer matches the process, or a chamber modification needs to be built correctly the first time. YTI fabricates the custom hardware that keeps those systems serviceable, leak-tight, and production-ready.

Our fabrication work supports vacuum coating equipment, cryogenic systems, diffusion-pumped chambers, electron-beam systems, sputtering systems, research tools, and legacy high-vacuum equipment. We can work from drawings, samples, damaged parts, field measurements, or system requirements, then machine, weld, assemble, and verify the component for fit and serviceability.

If the project is part of a larger redesign, chamber upgrade, or automation project, see custom vacuum engineering & fabrication. If you need replacement parts for an existing system, see vacuum coating & cryogenic chiller components.

Cold traps, feedthroughs, flanges & adapters

Vacuum hardware we fabricate

YTI fabricates both one-off components and repeat replacement parts for vacuum and high-vacuum systems. If your component is not listed, send photos, dimensions, drawings, or the failed part and we will confirm the best fabrication path.

Cold Traps & Cryogenic Traps

Custom cold traps, baffles, trap bodies, coil supports, and cryogenic hardware built to protect pumps, reduce vapor load, and fit your chamber layout.

Electrical, Fluid & Rotary Feedthroughs

Feedthrough repair, replacement, adaptation, and custom fabrication for electrical power, signals, cooling water, gas, motion, and rotary transfer.

Vacuum Flanges & Adapters

Custom flanges, adapter plates, reducers, bolt patterns, transition pieces, and replacement hardware for chamber, pump, valve, and source connections.

Blank-Off Plates & Base Plates

New and resurfaced blank-off plates, base plates, top plates, cover plates, access plates, and custom machined chamber interfaces.

Vacuum Manifolds & Piping

Custom manifolds, welded vacuum piping, pump connections, valve transitions, gas lines, and process plumbing fabricated for clean routing and service access.

Chamber Modifications

Ports, flanges, access points, source mounts, feedthrough locations, brackets, and hardware modifications added to existing vacuum chambers.

Can YTI fabricate from a damaged sample?
Yes. If a drawing is unavailable, YTI can often work from the failed component, photos, measurements, or system requirements. Send what you have and we will recommend the best next step. Contact YTI →
Can you fabricate a replacement for obsolete vacuum hardware?
Yes. Custom fabrication is often the best path when a cold trap, flange, feedthrough, adapter, or chamber component is discontinued, damaged, or no longer supported.

Common fabrication needs

Problems custom vacuum fabrication solves

Whether the goal is restoring a damaged component, adapting new equipment, or improving reliability, YTI fabricates hardware around the exact vacuum, fitment, and process requirements of your system.

Obsolete Components

Legacy parts that are unavailable from the original manufacturer can often be duplicated, adapted, repaired, or redesigned.

Mismatched Flanges

Adapter flanges, bolt-pattern changes, reducers, spacers, and transition plates solve fitment issues between chambers, pumps, valves, and sources.

Leaking or Damaged Hardware

Cracked welds, damaged sealing faces, worn plates, leaking fittings, and distorted hardware can be repaired, resurfaced, replaced, or rebuilt.

New Feedthrough Requirements

Electrical, fluid, gas, cooling, signal, and motion requirements can be added or modified when the chamber process changes.

Pump Protection & Vapor Load

Cold traps, baffles, and custom vapor-management hardware help protect pumps and improve process stability.

Chamber Upgrade Projects

New ports, source mounts, service access, manifolds, and hardware modifications support upgraded processes and expanded capability.

From measurement to finished hardware

What YTI fabrication includes

Every fabrication project starts with the real use case: the chamber, vacuum level, sealing interface, process conditions, service access, and part availability. From there, YTI builds the component to fit, seal, and perform.

Design Review

We review drawings, samples, dimensions, photos, sealing requirements, chamber layout, materials, and process conditions before fabrication begins.

Precision Machining

Machined plates, flanges, adapters, sealing faces, bores, bolt patterns, brackets, and component interfaces built to the required fit.

Vacuum Welding

Welded stainless hardware, manifolds, trap bodies, feedthrough assemblies, chamber ports, and vacuum piping fabricated for high-vacuum service.

Fitment & Assembly

Finished components are assembled and checked for geometry, connection points, clearance, bolt alignment, and serviceability.

Leak-Ready Verification

YTI fabricates with vacuum integrity in mind and can support leak detection, troubleshooting, and field verification when required.

Documentation & Support

Projects can include notes, measurements, recommendations, and support for installation, repair, or future replacement planning.

From concept to installed component

How custom vacuum fabrication works

Step 01

Scope

Send the drawing, sample, failed part, photos, dimensions, chamber information, or process requirement. We identify the component function, fit, sealing interface, and urgency.

Step 02

Design & Quote

YTI reviews materials, geometry, ports, bolt patterns, sealing faces, cooling or electrical needs, and fabrication complexity, then provides a practical fabrication path.

Step 03

Machine & Weld

The component is machined, welded, modified, resurfaced, or assembled by our in-house fabrication team using vacuum-system experience.

Step 04

Verify & Support

The finished part is checked for fit, function, and serviceability. YTI can support installation, leak troubleshooting, or field service if the project requires it.

Fabrication can be handled as a standalone component project or as part of a larger chamber upgrade, coating-system repair, or field-service job. See full service details →
