Hy-Lok compression fittings are the reliable choice for stationary and mobile hydrogen applications. They offer high reliability, low leakage rates and a long service life. Thanks to their proven design, the compression fittings remain absolutely leak-tight even under helium test conditions.
EC-79 type approval for selected 316/316L stainless steel versions and production in an ISO 9001-certified manufacturing facility guarantee the highest quality. The wide range of fitting designs offer many different combination options with connection types in accordance with ASME B1.20.2 (NPT) and SAE J1926-2/-3. They are tested for pressures up to 350 bar (5,076 psig) and temperatures from -40 °C to +85 °C. Simple initial assembly, disassembly and reassembly make these components particularly easy to service. In addition, a heat tracing code (HTC) enables complete traceability of the raw materials.
Depending on the version, Hy-Lok compression fittings also meet other approvals such as DVGW, TÜV and Lloyd's Register. They offer a durable, reliable solution for hydrogen systems in a wide range of industrial applications.
