Hose and Fitting Supply has the ISO 5675 hose couplers you need for your tractors and agricultural equipment. ISO 5675 hydraulic couplers meet the international standard used for quick disconnects on modern tractor hydraulic systems. Our ISO 5675 ag fittings interchange with Parker 4000, Safeway S20, Faster NS and Tomco PC Series connectors.

We offer hydraulic quick connect ISO 5675 connectors as paired sets, and as separate couplers and plugs for repairing worn or damaged fittings. Both types of connectors are available in ¼, 3/8, ½, and ¾ inch sizes. We also have replacements for Pioneer coupler plugs to keep dust and dirt out of your fittings.
