DANFOSS / EATON/HANSEN CPLNG

Description & Features

Designed for demanding fluid transfer across agriculture, construction, oil and gas, and a broad range of industrial applications, this brass female half coupling offers reliable quick connect and disconnect performance without the need for special tools. The ball lock internal mechanism and Buna-N seals support a rated flow of 6 gallons per minute, with operating pressures that exceed ISO 16028 requirements, the coupling also carries ISO 7241-1 Series B certification.

The Danfoss / Eaton Hansen HK Series Quick Disconnect Couplings Socket features a push-to-connect end on one side and a 3/8" NPTF port on the other, making it straightforward to integrate into existing hydraulic tool and fluid transfer setups. Brass construction and a minimum working temperature rating of -40°F extend its suitability to military, aerospace, medical, and chemical service environments. The 2-way valve configuration and absence of a safety locking mechanism keep the design simple and field-practical.
