Vacuum Parts, Components
& Cryogenic Refrigerant
Find replacement parts for vacuum coating, electron-beam deposition and cryogenic systems through YTI’s two dedicated parts catalogs. Browse stocked and custom vacuum components—including Sloan-style magnets, sensor crystals, feedthroughs, cold traps, manifolds and adapters—or locate model-specific refrigerant charges for supported Polycold and Telemark cryochillers.

Start with the part—not a generic service request
Vacuum coating and cryogenic systems often remain productive long after individual replacement parts become difficult to source. A failed magnet, feedthrough, sensor crystal, cold trap, manifold or refrigerant-related component can stop a system that is otherwise capable of years of additional service.
This page is the central starting point for YTI vacuum parts. Use the Vacuum Components & Custom Parts catalog when you need mechanical, electrical, deposition-source or custom-fabricated hardware. Use the Cryochiller Refrigerant Charges catalog when you need model-specific refrigerant pricing and part numbers for supported cryogenic refrigeration equipment.
If the required item is obsolete, damaged or not listed, YTI can also evaluate fabrication, refurbishment, repair, stocking or an engineered replacement instead of forcing unnecessary replacement of the larger system.

YTI supports more than catalog inventory
A vacuum part can be unavailable because it is obsolete, proprietary, damaged beyond repair, unique to a modified machine or no longer supported by the original manufacturer. YTI can evaluate alternate paths based on the part and the larger system.
Component Stocking
Plan and stock the parts most likely to create production downtime across vacuum coating, deposition and cryogenic systems.
Explore component stocking →Cold Traps, Feedthroughs & Flanges
Custom vacuum hardware for obsolete interfaces, chamber modifications, process changes and application-specific requirements.
Explore custom fabrication →Custom Vacuum Machining
Flanges, adapters, plates, brackets, manifolds, pump interfaces, mounts, fixtures and legacy replacement components.
Explore machining →Power Supply & Electronics Repair
Repair and refurbishment paths for power supplies, controllers, sweep electronics, sensor systems and obsolete assemblies.
Explore electronics repair →Refrigerant Recharge
For equipment already low on charge, leaking or not reaching temperature, move from supply-only into diagnosis and recharge support.
Explore recharge service →Cryochiller & Vacuum Repair
If the failed component is only one symptom of a larger system problem, YTI can troubleshoot the complete vacuum or cryogenic system.

Common questions about replacement vacuum parts
What vacuum parts does YTI supply?
YTI supports vacuum coating and cryogenic equipment with stocked and custom components including Sloan-style magnets, deposition sensor crystals, feedthroughs, cold traps, refrigeration traps, manifolds, adapters, electronics, cryogenic support parts and model-specific refrigerant charges.
Where can I see YTI parts that are currently listed?
Use the Vacuum Components & Custom Parts catalog for stocked or made-to-order hardware. Use the Cryochiller Refrigerant Charges catalog for refrigerant part numbers, models and pricing.
Can YTI make an obsolete vacuum component?
Depending on the component and application, YTI can evaluate custom machining, fabrication, feedthrough manufacturing, manifolds, adapters, traps, electronics repair or another replacement path. Photos, drawings, dimensions and the failed part itself can help determine feasibility.
Does YTI support legacy vacuum coating equipment?
Yes. YTI supports current and legacy vacuum coating, electron-beam deposition, pumping and cryogenic equipment. The best replacement path may involve stocked inventory, refurbishment, fabrication, adaptation or reproduction of discontinued hardware.
Does YTI sell Polycold-style refrigerant?
YTI supports model-specific refrigerant supply for supported Polycold-style cryochillers and related cryogenic systems. The exact equipment configuration and service history should be confirmed before selecting a charge.
Can YTI help determine which spare parts we should stock?
Yes. YTI’s Component Stocking service can review equipment criticality, failure history, lead times and production risk to help build a practical critical-spares plan.
What should I send if I do not know the part number?
Send the equipment manufacturer and model along with clear photos of the component, surrounding connections, labels, dimensions and the reason the part is needed. For cryogenic refrigerant requests, also include the refrigerant label and service history.
Can YTI repair a part instead of replacing it?
For many electronic, mechanical, vacuum and cryogenic components, repair or refurbishment may be an option. YTI can review the failed component and determine whether repair, replacement, fabrication or a larger system service is the better path.
Looking for a vacuum part you cannot find?
Send YTI the equipment model, part number, photos, dimensions, refrigerant information or failed component. The team can help identify the right catalog, confirm availability or evaluate a custom replacement path.
