Coupling 3000 Series FemaleBrass

Description & Features

Designed for industrial breathing air, general pneumatics, maintenance and repair, and fluid transfer service, the Coupling 3000 Series Female Brass is a push-to-connect female half from Eaton's Hansen sub-brand. Constructed from brass with a Buna-N seal, it suits a wide range of fluid compatibility requirements and performs reliably down to -40°F minimum working temperature.

Connection is fast and tool-free using a ball lock mechanism with pin lock safety retention, supporting flow rates up to 180 gallons per minute. The coupling meets US Industrial Interchange, ISO 6150 Series B, and A-A-59439 compliance standards, and exceeds ISO 16028 operating pressure requirements. The two-way valve design controls flow in both connect and disconnect states, making it a practical choice for pressurized line and hose applications across industrial environments.

Question by: Brent S on Jun 26, 2025, 12:16 PM
Will this here fitting work alright for hooking up to an air compressor?

This brass coupling is well-suited for general pneumatics applications. It's also rated for industrial breathing air, so it should handle typical air compressor duties just fine.
