About Leland Gas Technologies

For more than five decades, Leland Gas Technologies has occupied a specialized corner of the industrial and consumer gas world: the design and manufacture of high-pressure, disposable gas-filled cylinders and related gas-handling products. Founded in 1964 and headquartered in South Plainfield, New Jersey, Leland has grown from a niche producer of soda syphons and small aerospace cylinders into a globally recognized name trusted by engineers, safety professionals, athletes, and outdoor enthusiasts alike.

What sets Leland apart is a deliberately narrow product focus. Rather than trying to be everything to everyone, Leland Gas Technologies concentrates its deep engineering expertise on one thing: packaging gases safely and reliably into non-refillable cartridges and cylinders ranging from 1.0 ml to 2.2 liters of water capacity. That precision of purpose has earned the company ISO 9001:2015 certification through TUV Rheinland, as well as U.S. Department of Transportation (DOT) approvals for non-refillable gas-filled cylinders and FAA component approvals for CO2 and oxygen-filled cylinders used in aerospace applications.

Industries and Applications

Leland’s cylinders are found in an impressive range of industries. Medical, marine, beverage, aerospace, sports, education, and science sectors all rely on Leland’s precision-filled gas products. Standard off-the-shelf offerings include oxygen, CO2, helium, and nitrous oxide cylinders, while calibration and scientific-grade gas blends are available in most cylinder sizes for laboratory and research applications. On the consumer and sporting side, Leland cylinders power everything from cream whippers and seltzer bottles to life jackets and sporting inflation devices.

One of the most practical automotive and outdoor applications of Leland’s technology is in tire repair kits. Leland’s CO2 cylinders serve as the inflation source in portable emergency tire repair systems, giving drivers, cyclists, and off-road enthusiasts a compact, reliable way to reinflate a flat tire without a bulky pump or electrical compressor. Whether you’re on a remote trail or stuck on the side of the highway, a CO2-powered tire repair kit built around a Leland cylinder delivers fast, effective inflation when you need it most.

Quality, Sustainability, and Trust

Leland’s long-standing reputation is built on honest trade practices and a genuine commitment to environmental responsibility. All of their gas-filled cylinder and cartridge products are manufactured from recyclable steel, and the company actively educates customers on proper emptying and recycling procedures to minimize waste. Leland also provides detailed shelf-life guidance for all product types — cylinders with welded closures carry an indefinite shelf life, while pushpin-valve types are rated for approximately four years under proper storage conditions (between 32°F and 120°F).

With certifications that span military, aerospace, commercial, and consumer standards, and with a technical document library built up since 1965, Leland Gas Technologies brings an engineering-first mindset to every cylinder it produces. For anyone who depends on compressed gas in a critical moment — whether in a medical setting, on open water, or on the side of a road with a flat tire — Leland is a brand that delivers with precision and consistency.
