Pneumatic Products, Standard Couplings & Nipples

Series 315, DN 7.5

  • Extremely high flow capacity
  • Low connection force
  • One-hand operated


Series 315 couplings are lightweight and easy to handle yet strong and durable. The Series includes a wide range of connections as well as anti-hose whip nipples. The Series eSafe 315version is disconnected in two stages in order to vent the coupling and minimize the risk of sudden component separation, which has the potential to cause operator injury. The one-handed operation ensures easy handling. The eSafe version complies with ISO Standard 4414 and EN 983.


Series 315 is available in eSafe and Multi-Link versions.
