CNH Machines and Their Hydraulic Quick Couplings
CNH Industrial is the parent of Case IH, New Holland and Steyr agricultural brands, plus Case Construction. Across the CNH family, tractor rear outlets use ISO 5675, construction loader auxiliaries use flat-face (ISO 16028 style), and older or service lines may carry ISO 7241 ball-lock couplings.
Coupling Profiles You Will Find on CNH Equipment
The table below summarises the quick-coupling profiles most commonly used across CNH machine families. It is a field guide, not a guarantee: verify the profile on your specific machine before ordering.
| Machine family | Common profile | Typical sizes | Typical threads |
|---|---|---|---|
| Tractor rear outlets (CNH brands) | ISO 5675 (agricultural) | 1/2" ISO 5675 | BSPP / NPT |
| Construction auxiliaries | Flat-face (ISO 16028 style) | 1/2" flat face | NPT / ORFS |
| Service lines | Ball-lock ISO 7241 | 1/2" - 3/4" | NPT / BSPP |
