Environment
Low-outgassing couplings and screws for high-vacuum, analytical and space applications where released gas would spoil vacuum quality or measurement accuracy.
Overview
In high-precision, vacuum and space environments, outgassing (the slow release of adsorbed gas from a material) contaminates surfaces, reduces vacuum quality and harms measurement accuracy. Low-outgassing materials and surface finishing are essential. NBK selects stainless steel, titanium and vacuum-compatible alloys and, for insulating or ultra-low-outgassing needs, PEEK and VESPEL parts, with cleaning and finishing before installation.
Optional ultrasonic cleaning further lowers surface contamination. Complete specifications and CAD files are available per product on nbk1560.com. Share your vacuum level and cleanliness targets and our engineers will match a low-outgassing coupling or screw.
Low-outgassing materials protect vacuum quality and measurement accuracy.
Suited to UHV, analytics and space instrumentation.
Surface finishing and optional ultrasonic cleaning before install.
Vented (drilled) socket-head cap screws that release trapped air and gases during pump-down to prevent virtual leaks in vacuum and cleanroom systems.
Grade 2 and Grade 5 titanium socket-head cap and machine screws: lightweight, non-magnetic and chemically resistant for medical, aerospace and semiconductor use.
Fasteners for service far beyond 200 °C: SUS316L, molybdenum, ceramic, Vespel, Hastelloy and Inconel screws for furnaces, plasma and high-temperature process equipment.
Outgassing is the slow release of gas adsorbed in or on a material under vacuum. Low-outgassing parts use materials and finishes that release very little gas, which keeps the vacuum clean and stable. That is critical for UHV, analytical and space systems.
Stainless steel, titanium and vacuum-compatible alloys are standard; for insulating or ultra-low-outgassing needs, PEEK (MSXP coupling) and VESPEL (SPDC-C screw, MOHS coupling) parts are used, often with additional cleaning.
Our engineers help you select the right coupling or screw, and prepare a quotation.
