Accu-Glass Products

What Accu-Glass Products does

Accu-Glass Products, Inc. is a privately held US manufacturer of ultrahigh vacuum (UHV) and high vacuum (HV) components, headquartered at 25047 Anza Drive, Valencia, California. The company produces an extensive catalog of vacuum feedthroughs covering electrical, fiber optic, coaxial, thermocouple, fluid, motion, and power transfer, alongside Conflat (CF) and ISO KF/LF flanges, vacuum fittings, vented fasteners, copper and Viton gaskets, vacuum sealants, lubricants, solder, and raw vacuum-compatible materials including OFE copper, 304 stainless steel, PEEK, Macor ceramic, and Kapton. Products are rated for pressures down to 1x10-10 Torr and temperatures up to 450°C, and are designed for compatibility with industry standards ASTM E2734/E2734M-10, ISO/TS 3369-2, and ISO 2861, ensuring interoperability with flanges from major vacuum equipment manufacturers worldwide.

The business model is B2B component sales, primarily through a direct e-commerce channel offering 24/7 website ordering with next business day fulfillment, supplemented by a distributor network. Pricing is quote-based and not publicly disclosed. Products are sold as complete kits or individual piece components, and the company also offers custom cable and custom flange manufacturing services backed by sales engineering. Revenue is generated through one-time component sales rather than recurring contracts or subscriptions.

The customer base is segmented horizontally across scientific research institutions, industrial vacuum equipment manufacturers (including semiconductor, thin film deposition, and surface analysis), and advanced technology sectors such as aerospace, chemical processing, healthcare, and transportation. No management team, ownership, headcount, funding, or revenue data is publicly disclosed, and no named end-customer logos are present in the available sources.

Core offering

Accu-Glass Products, Inc. manufactures ultrahigh vacuum (UHV) and high vacuum (HV) feedthroughs, flanges, fittings, and accessories that provide connectivity between air and vacuum environments. The company offers a broad catalog of standard and custom precision vacuum hardware designed for scientific research and industrial vacuum applications.

Product overview

Accu-Glass Products is a manufacturer of Ultrahigh Vacuum (UHV) and High Vacuum (HV) components offering end-to-end air-to-vacuum connectivity solutions. The product portfolio centers on feedthroughs (electrical, fiber optic, coaxial, thermocouple, fluid, motion, and power) that enable signals, power, and materials to transfer between atmosphere and vacuum environments. These feedthroughs are complemented by a comprehensive range of CF (Conflat) and ISO KF/LF flanges, fittings, and hardware using industry-standard sealing technologies (copper gasket knife-edge for UHV, centering ring/O-ring for HV). Supporting materials include raw vacuum-compatible stocks (OFE copper, 304 stainless steel, PEEK, Macor ceramic, polyimide/Kapton), vented fasteners to prevent virtual leaks, vacuum-rated consumables (gaskets, sealants, lubricants, solder), and Kapton-based thermal and electrical insulation components. The company also provides custom cable and flange manufacturing services for specialized requirements. All products are designed for scientific research, semiconductor, and industrial vacuum applications.

Direct peers

• Kurt J. Lesker Company: One of the largest global manufacturers and distributors of vacuum components, feedthroughs, flanges, and fittings. Directly comparable to Accu-Glass across the same CF/ISO product categories, custom-fabrication services, and standards-compliant UHV portfolio, with a much broader catalog and global footprint.
• MDC Vacuum Products: Long-standing US-based manufacturer of vacuum components including CF/ISO flanges, fittings, feedthroughs, and viewports. Closely overlaps Accu-Glass on catalog structure, standard compliance, and direct-to-customer B2B sales model.
• Nor-Cal Products: California-based manufacturer specializing in vacuum chambers, flanges, fittings, viewports, and feedthroughs for HV/UHV applications. Shares the same West Coast specialty-manufacturer DNA, custom-fabrication emphasis, and semiconductor/research customer base as Accu-Glass.
• Duniway Stockroom: Specialty distributor and re-manufacturer of vacuum components, ion gauges, and UHV hardware. Competes with Accu-Glass in the same standards-compliant feedthrough, flange, and fitting categories, primarily serving semiconductor and research customers.
• Huntington Mechanical Labs: Manufacturer of vacuum chambers, flanges, and custom UHV/HV systems with a comparable specialty-components catalog. Overlaps Accu-Glass on flange technology, viewports, and custom engineering services for research and industrial customers.

Broad incumbents

• Pfeiffer Vacuum: Global vacuum technology leader offering pumps, leak detectors, components, and complete vacuum systems across far broader end-markets. Adjacent to Accu-Glass on the components side (feedthroughs, flanges, fittings) but serves as a much larger, systems-level incumbent in the same vacuum-technology stack.
• VAT Group: Global leader in vacuum valves and related components serving semiconductor, display, and industrial vacuum markets. Comparable to Accu-Glass on vacuum-component manufacturing and standards compliance, but operates at significantly larger scale with a public-company balance sheet.
• Edwards Vacuum: Subsidiary of Atlas Copco providing vacuum pumps, abatement, and related components for semiconductor and industrial applications. Touches the same end-customers as Accu-Glass but with a broader systems-level offering that includes the components Accu-Glass specializes in.
• Agilent Technologies Vacuum Products: Vacuum products division of Agilent supplying ion pumps, gauges, and UHV components to research and industrial customers. Overlaps Accu-Glass on UHV hardware, fittings, and feedthroughs but operates as part of a much larger diversified analytical-instruments company.

Emerging players

• HVA (High Vacuum Apparatus): Specialty manufacturer of high- and ultra-high vacuum components, flanges, and feedthroughs. Comparable niche positioning to Accu-Glass with a smaller catalog focused on standards-compliant HV/UHV hardware for research and industrial customers.
