What Oseco does
Oseco (operating commercially as OsecoElfab) is a Tulsa, Oklahoma-headquartered manufacturer of customized rupture discs, explosion vents, and associated pressure relief and explosion protection products for industrial customers. Its technology centers on proprietary designs such as reverse buckling rupture discs (the LoKr family), welded safety cartridges (Oseco Safety Cartridge, LoKr Duo), sanitary welded discs for bioprocessing (Pure-Gard, Opti-Gard variants), and specialty products for lithium-ion battery and gas insulated switchgear applications (Dual-Gard, PRO-LP, PLR). Core products are designed to ASME XIII and carry CE marking, with complementary sensors (Flo-Tel, AMS, Vent-Tel) that detect disc burst events. Engineering services — ASME flow testing, customized design, site surveys, stock rationalization, expedited orders, and training — are bundled with product sales.
The company sells primarily through an enterprise field sales motion, including a dedicated EPC team for major capital projects and regional offices in the United Kingdom (EMEA) and Singapore (Asia-Pacific), with quote-based pricing on engineered-to-order safety equipment. End markets span chemical/petrochemical, refining, semiconductor manufacturing, pharmaceutical and biotech, power generation and energy storage (including BESS), energy (upstream, midstream, renewables), aerospace/defense/propulsion, and OEM/industrial equipment. OsecoElfab is a wholly-owned subsidiary of Halma plc, a London Stock Exchange-listed group focused on safety, environmental, and medical technologies, and is led by Managing Director Rachel Mansfield (appointed 2025). Notable 2025 initiatives include the launch of the OE Aerospace sub-brand, the LoKr Duo two-piece safety cartridge, and receipt of the UK King's Award for Enterprise: International Trade.
