Pneumatic Products, Standard Couplings & Nipples

Series 408, DN 9.5

  • Strong and durable
  • One-hand operated
  • Low connection force

Series 408 couplings offer high flow capacity and have higher resistance to vibrations than competitive couplings. The Series is suitable for vacuum service. A wide range of connections is available, as well as anti-hose whip nipples.
