Danfoss / Eaton Cplng HK Series

Description & Features

A female half socket with push-to-connect inlet and 3/4" NPTF port, the Danfoss / Eaton Cplng HK Series coupling is designed for fast, tool-free hydraulic connections in demanding industrial and mobile applications. The ball lock internal mechanism provides secure engagement, while Buna-N seals and carbon steel construction support reliable performance across a wide temperature range, down to -40°F.

Certified to ISO 7241-1 Series B, this coupling exceeds ISO 16028 operating pressures and handles flow rates up to 26 gallons per minute. The two-way valve configuration supports bidirectional flow control, making it well suited for agriculture, construction, fluid transfer, oil and gas, transportation, and aerospace applications, among others.

With no special tools required for connection or disconnection, this socket integrates efficiently into high-cycle hydraulic circuits where downtime matters. The Hansen sub-brand lineage reflects a long-standing standard in quick disconnect coupling design across general industry and mobile equipment sectors.

Product Questions & Answers (1)

Question by: Dale A on Apr 23, 2025, 5:14 PM
Will this work with regular hydraulic fluid or do I need something special?
Answer by: Customer Support on Apr 24, 2025, 7:51 PM
This coupling uses Buna-N seals, which are compatible with standard hydraulic fluids. You shouldn't need anything special for regular use.
