Haskel delivers a comprehensive range of high‑pressure solutions engineered specifically for the unique challenges of hydrogen service. From BuTech valves to precision‑manufactured fittings and tubing, each component is designed to maintain leak‑free integrity while resisting hydrogen embrittlement—ensuring long‑term durability and safety in demanding high‑pressure environments.
To ensure the highest level of safety and reliability, medium‑ and high‑pressure BuTech connections require specialized coning and threading tools. These tools prepare tubing ends with precise geometrics, enabling secure metal‑to‑metal sealing and ensuring each assembly meets critical hydrogen service standards.
BuTech hand tools are designed to permit on-sight end preparation for tubing. The coning tool uses a precision collet to maintain concentricity between the tube and the cutter blades. The threading tool uses an adjustable split die and a precision guide bushing to cut a perfect thread.
