Danfoss Hansen® quick disconnect couplings

Maximize system uptime

Featuring the latest design innovations, Danfoss Hansen quick disconnect couplings maximize ease of use and system uptime in key hydraulic, pneumatic and thermal management applications. Offered in carbon, stainless steel and brass, Danfoss Hansen quick-disconnect couplings meets or exceeds industry standards and are backed by the industry’s leading 3-year warranty.

  • Benefits - Quick connect and disconnect
  • Time savings - No need for special tools
  • High performance - Exceeds ISO 16028 operating pressures

Couplings provide a means of quickly connecting and disconnecting a line without a loss of fluid or entrance of air into a system.

If equipment needs to be assembled quickly or if it needs routine servicing or repair, then a coupling is a better choice for a fluid connection.

When incorporating Quick Disconnect couplings, spillage of costly and dangerous liquids and other fluids can also be prevented. This contributes to a cleaner environment, making way for safer working conditions.

  • Low air inclusions and connect under pressure capability up to 500psi.
  • Excellent vibration resistance and corrosion performance.
  • Up to 115% more flow over competing brands

Core 4 Pneumatic quick disconnects

Auto-Flo series

Auto-Flo series

Designed with high flow and easy automatic connections.

Features:

  • Auto-Flo 23 is the first automatic universal quick disconnect coupling designed to operate with Industrial, ARO 210 and Tru Flate Interchange plugs/males.

  • Easy, automatic push-to-connect design provides instantaneous connection and disconnection of lines.

  • The universal design makes Auto-Flo an extremely flexible coupling series.

1000/400/500 series

1000/400/500 series

Industrial Interchange coupling that is rugged and reliable designed for use with compressed air, gases, and liquids.

Features:

  • Ball latching mechanism.

  • Optional sleeve lock prevents accidental disconnection.

  • All sizes accept US Industrial Interchange.

  • 400 series accepts Tru-Flate Interchange.

  • Brass body with nickel plated steel offers high corrosion resistance.

210/310 series

210/310 series

Danfoss ARO 210/ 310 interchange offers rugged corrosion resistant performance.

Features:

  • Danfoss' ARO 210/310 interchange offers a pin-lock design with alloy steel locking pins and automatic push-to-connect operation.

  • Zinc trivalent plated carbon steel offers high durability with superior corrosion performance.

2RL/3RL series

2RL/3RL series

Danfoss' 2RL/3RL ring lock series have a unique interchange which are designed for use with compressed air.

Features:

  • High Flow capacity.

  • Push to connect with a ring lock sleeve designed to prevent accidental disconnection.

  • Standard body material: Zinc trivalent plated steel.

Why use a quick disconnect coupling over a conventional threaded connection?

Traditional threaded fitting:

  • No shut-off system: leakage after disconnection
  • Cannot rotate while connected - line twisting decreases life of hose
  • Additional assembly time
  • Difficult handling, waste of time to disassemble (maintenance)
  • Frequent disconnection effects seating performance, increases likelihood of leaking

Quick disconnect coupling:

  • Shut-off system: sealing achieved upon disconnection
  • Can rotate while connected, taking stress out of hose and extending life
  • Ease of assembly in tight spaces
  • Easy and fast to use (without tool), time saving and economical
  • Increased mobility and access for maintenance

Danfoss' newly redesigned Flat Face quick disconnect couplings

Our newly redesigned Flat Face (FF) quick disconnect couplings provide greater performance at higher pressures along with higher flow rates.

Danfoss' Flat Face series quick disconnect couplings are designed to connect top performing hydraulic lines without fluid loss and offer increased pressures to help machine manufacturers meet market demand for high pressure and high impulse pressure solutions.

The renewed flat faced quick disconnect couplings reduce pressure drops and decrease energy loss, resulting in lower fuel and energy consumption. Plus, Danfoss' Guardian Seal nickel-free plating offers outstanding corrosion resistance in tough environments for up to 1,000 hours.

Multiplate flat face coupling system

Our innovative multiplate system (Multi-FF) extends all the benefits of Danfoss flat face couplings. Designed for any application demanding multiple hydraulic fluid connections for power transmission, our brand new system supports two to six flat face couplings simultaneously.
