Hansen ST series straight-through couplings
Hansen ST series straight-through couplings
Hansen ST couplings are specifically designed as straight-through couplings without self-sealing valves.
- Their smooth, unrestricted bore permits full flow of liquids and gases
- Alternative hose stem and threaded end connections give neat, compact installations with the minimum number of joints
- Availability in brass and stainless steel allows a wide variety of fluids to be handled without corrosion.
Product Details
Applications include: water, cooling water, washdown, grease, lubricants, general fluid transfer etc.
A technical brochure and Safety Information Notice on this range of couplings is available in the downloads (tab) section shown above. A copy of these documents should be distributed and read by all individuals responsible for using and/or selecting this range of couplings, prior to use. For specific applications and working conditions , please consult Guyson Technical Sales Department.
Hansen ST Couplings can also be supplied as part of a ready-to-use flexible hose assembly: see our Kaptech flexible hose range for details.
