Description & Features

The Danfoss / Eaton Compression Male Connector is crafted for use with plastic copper and aluminum tubing. This fitting is designed to withstand working pressures up to 2000 psi ensuring reliability in demanding applications like instrumentation and hydraulic systems. Constructed from CA360 brass it offers a robust solution for connecting tubing without the need for flaring.

MPN: C1HR18

Supplier Part Number: 68X4X4

For optimal performance this fitting is suitable for use with temperatures ranging from -65F to +250F when paired with metal tubing. When compatible plastic tubing is used adherence to the tubing's temperature range is essential. The fitting meets stringent ASA ASME and SAE standards and offers fair vibration resistance with the option of using a long nut for enhanced vibration resistance.

The assembly process is straightforward involving cutting the tubing to the desired length sliding the nut and sleeve onto the tube and ensuring the tubing is fully inserted into the fitting body. Tighten the nut hand-tight followed by additional wrench turns as specified by the tubing size.

Question by: Wayne W on Apr 24, 2025, 7:51 PM
fitting says it works with plastic tubing but also lists a temp range for metal -- does the plastic tubing have its own limits i need to worry about?
Answer by: Customer Support on Apr 26, 2025, 8:13 AM
Metal tubing paired with this fitting handles anywhere from -65F up to 250F without issue. Plastic tubing is a different story. Whatever tubing you're running, its own rated temperature range takes priority. So before you put this on a plastic line, check what that tubing is spec'd for and make sure your system stays within those bounds.
