The Danfoss / Eaton Hansen 500 Series Quick Disconnect Couplings Plug is designed for robust performance in general pneumatics construction and industrial plants. Precision-engineered to meet MIL-C-4109 standards for industrial interchangeability this coupling features a 1/2-14 NPT thread and a -08 coupling size.

The Buna-N seal material ensures reliable sealing across a broad temperature range from -40deg;F to high operational pressures while the brass body and automatic sleeve lock enhance durability and secure connections.

Product Questions & Answers (2)

Question by: Bobby M on Feb 1, 2026, 10:03 AM
Does this male half swap out with the Aeroquip FD40 Series or am I gonna need an adapter to make it work?
Answer by: Customer Support on Feb 3, 2026, 8:30 AM
No adapter needed. The FD40 Series is one of the direct interchanges for this coupling, along with the Aeroquip FD41 Series (Aro 210) and Parker Automotive male halves. The thread is 1/2-14 Male NPT, so as long as your mating connection matches that, you should be good to go right out of the box.
Question by: Neal M on Dec 17, 2025, 5:38 PM
Will this work with a standard air compressor setup? I'm using Aeroquip FD40 series stuff now.
Answer by: Customer Support on Dec 19, 2025, 4:19 PM
This Eaton / Aeroquip Hansen 500 Series plug is designed to interchange directly with Aeroquip FD40 Series couplings, as well as FD41 Series (Aro 210) and Parker (Automotive) male halves. It meets MIL-C-4109 standards for industrial interchangeability.
