Stainless steel TW couplings – robust tanker couplings for demanding applications
TW couplings (tank truck couplings) made of stainless steel in accordance with DIN EN 14420-6 are the ideal solution when maximum resistance to aggressive media, pressure and temperature is required.
The standardised bayonet system enables safe, tight and quick coupling and uncoupling of hoses, pipes and tank systems. Reliable even under heavy use, vibration or changing operating conditions.
AISI 316 (1.4404) stainless steel is characterised by its high corrosion resistance and hygienic surface. This makes these couplings suitable even for demanding media such as chemicals, foodstuffs or pharmaceutical liquids. Investing in TW couplings made of stainless steel ensures the longevity of your systems.
