Ask A Question

Description & Features

Designed for industrial fluid transfer and general pneumatic applications, this brass quick disconnect coupling socket connects and disconnects without special tools, making it well suited for maintenance and repair environments where efficiency matters. The Danfoss / Eaton Straight Through Socket is a female half fitting with a ball lock mechanism, 3/8 in. port size, and a Push to Connect end on one side with a 3/8 in. NPTF thread on the other.

Buna-N seals provide reliable performance across a working temperature range starting at -40°F, while the two-way valve design supports controlled flow in demanding service conditions. Compliant with US Industrial Interchange, ISO 6150 Series B, and A-A-59439 standards, this fitting integrates with existing Hansen 3000 Series quick disconnect configurations. Flow capacity reaches up to 180 gallons per minute, and the coupling exceeds ISO 16028 operating pressure requirements.

Will this Eaton fitting work with my current Hansen 3000 series setup, or do I need to change everything out?

Since this Danfoss/Eaton socket is compliant with US Industrial Interchange, ISO 6150 Series B, and A-A-59439 standards, it is designed to integrate directly with existing Hansen 3000 Series quick disconnect configurations.
