Industry standard configuration. Compatible with all standard CGA regulators and delivery systems.
More gas per cylinder. Reduces changeouts and delivery frequency. Requires high-pressure rated regulators.
From precision welding to leak testing to semiconductor manufacturing — helium's unique properties make it indispensable across critical industries.
Helium is the industry standard for leak detection testing due to its small atomic size and inert properties. Used in automotive, HVAC, aerospace, refrigeration, pharmaceutical packaging, and any application requiring precise leak testing at ppb sensitivity levels. Compatible with all major mass spectrometer leak detectors.
Helium welding gas provides deeper penetration and higher heat input than argon, making it ideal for TIG welding of aluminum, stainless steel, copper, and magnesium. Pure helium or helium/argon blends improve weld quality on thick sections and high-conductivity metals. Available in all cylinder sizes.
Helium carrier gas is the preferred choice for gas chromatography (GC) and GC-MS applications. Its low molecular weight provides optimal separation efficiency and faster analysis times. UHP and Research Grade helium ensures clean baselines and accurate analytical results for laboratories worldwide.
Electronic-grade helium is essential for semiconductor fabrication: chamber purging, epitaxial crystal growth, cooling during wafer processing, and as a carrier gas for chemical vapor deposition (CVD). Ultra high purity grades ensure zero contamination in cleanroom environments.
Non-flammable and lighter than air, helium is the safe choice for balloon inflation — from party balloons and event décor to weather balloons, scientific research balloons, and advertising inflatables. Available in standard cylinders with balloon fill regulators and accessories.
Helium provides the controlled atmosphere required for optical fiber manufacturing, ensuring purity of the glass core. Also used in breathing mixtures (deep-sea diving), cryogenic research, wind tunnels, airbag inflation systems, and as a protective atmosphere in arc furnaces and metal heat treatment.
From industrial balloon grade to ultra high purity research grade — WSM supplies the full range. All grades available at 3.5K, 4.5K, and 6K PSI.
Every helium grade is verified at our ISO 17025 accredited laboratory using NIST-traceable analytical instruments. UHP, Research, and Electronic grades include full Certificate of Analysis with impurity breakdown.

Multiple cylinder sizes to match your volume — from portable field units to high-capacity industrial cylinders and tube trailers.
Additional cylinder sizes available — contact us for details. Tube trailers available for high-volume industrial users. All cylinders DOT certified · HAZMAT compliant · SDS included.
WSM supplies compressed helium gas at standard 2,200 PSI and ultra high pressure options at 3,500 PSI, 4,500 PSI, and 6,000 PSI. Higher pressure means more gas per cylinder, reducing the frequency of cylinder changeouts and deliveries. Ultra high pressure cylinders require compatible high-pressure regulators.
Helium welding gas is used as a shielding gas in TIG (GTAW) welding, particularly for aluminum, stainless steel, copper, and magnesium. Helium provides deeper weld penetration and higher heat input compared to argon, making it ideal for thick sections and high-conductivity metals. It can be used as pure helium or in helium/argon blends.
Helium is the industry-standard tracer gas for leak detection because of its very small atomic size (second smallest element), chemical inertness, non-flammability, and low natural atmospheric concentration (~5 ppm). These properties allow helium mass spectrometer leak detectors to identify leaks at parts-per-billion sensitivity levels. Used in automotive, HVAC, aerospace, pharmaceutical, and semiconductor manufacturing.
Gas chromatography (GC) requires UHP (99.999%) or Research Grade (99.9999%) helium as a carrier gas. Higher purity reduces baseline noise and improves detector sensitivity. For GC-MS applications, Research Grade is recommended. WSM supplies both grades with full Certificate of Analysis and NIST-traceable documentation.
Yes. WSM delivers compressed helium gas cylinders to all 50 U.S. states via ground freight. We also export to Latin America and the Caribbean from our Miami facility. Contact us for delivery timelines to your specific location.
Ultra high pressure helium refers to cylinders filled above the standard 2,200 PSI — specifically at 3,500 PSI, 4,500 PSI, or 6,000 PSI. These configurations hold significantly more gas per cylinder than standard pressure, reducing delivery frequency and cylinder changeouts for high-volume operations. Your regulator must be rated for the selected pressure.
Yes. Our ISO 17025 & 17034 accredited laboratory manufactures custom helium blends including He/Ar welding mixes, He/N₂ blends, and multi-component specialty mixtures. Contact us with your specifications for a custom quote — typical turnaround for custom blends is 3-7 business days.
