I am still new at this hydraulics game so I’m trying to learn. I know most QC are NOT compatible. My question is are the AG 1/2” ISO 5675 female QC Compatible with the male 1/2” ISO 7241–1, series A? They look nearly identical and have the exact same dimensions. One website that sells QC says they are compatible.


I ask this because I appear to have 1/2” AG female QC on the two sets of OEM rear loops I have. I have a flail mower with what appears to be 1/2” male QC ISO 7241-1 series A. I have run the flail mower with no issues or leaks. I only noticed this when I got the numbers off the male QC because wanted to order 4 more for a Top and Tilt set up. The numbers on the male QC identified it as ISO 7241-1 series A. The male QC is a LSQ S1-04PF 1/2” BSP. The female QC on the tractor is Dixon QC 4AGOF4-PV with 44/23 EU below.

The 1/2" body size ISO 5675 (AG) and ISO 7241A couplers are identical per the specifications. The screenshot below is the requirement straight from the ISO 5675 document.
