BOSS damp-slange-kobling
BOSS steam hose coupling is a specialised coupling solution for high-pressure steam installations. The construction is hose tail with safety collar and male thread per ANSI/ASME B 1.20.1/3 (NPT tapered thread). The material is galvanised steel or cast steel depending on variant. Max temperature 210 deg C makes it suitable for strong-steam applications in industrial process, brewery cleaning and pharma sterilisation. The BOSS system is specifically developed for steam hose applications where leak-free joints are critical due to thermal expansion and high pressures.

Frequently asked questions
What is the BOSS system?
BOSS is an industry standard for steam hose couplings specifically developed for high-pressure steam installations. The construction integrates hose tail with safety collar (preventing the hose from slipping off) and NPT male thread for connection to standard pipe systems. It's widespread in brewery, pharma sterilisation and industrial process where steam pressure and thermal cycling are challenges.
NPT or BSPP?
The BOSS coupling is supplied with NPT tapered thread per ANSI/ASME B 1.20.1/3. It is NOT compatible with BSPP/G-thread (parallel thread). Cross-check your existing pipe system before ordering.
What about safety clamp need?
For BOSS steam couplings we recommend supplementing with BOSS high-pressure steam safety clamp (SKU 5420) specifically developed to secure the BOSS coupling against separation under pressure. Use as a complete steam safety solution.
