Short Forged Nut

Hydraulic systems with extremely compact space (medium and low pressure).
Hard pipe connections in compact pneumatic systems.
Precision hard pipe connections inside instruments and meters.
Refrigeration and air conditioning systems (copper pipe connections, suitable for compatible refrigerants/lubricants).
Fuel systems (low-pressure part).
Hard pipe layouts in industrial machinery with limited space.
Local hard pipe connections in automobiles and aerospace (non-critical high-pressure systems).

Essential structural differences:
Short Rod Nut adopts a split design (nut + movable bushing), relying on the 45° cone surface of the bushing to achieve sealing; while Short Forged Nut is an integrated forging structure, with a 45° sealing cone surface directly processed on the nut body, and no independent bushing.
Differences in applicable objects:
Short Rod Nut is specifically used to connect hoses or flat-end steel pipes (need to be matched with accessories such as ferrules); Short Forged Nut is only suitable for SAE 45° flared hard steel pipes, relying on the prefabricated 45° flaring of the steel pipe to form a seal.
Comparison of spatial characteristics:
Both are compact designs, but Short Forged Nut has a shorter axial length due to the elimination of the bushing structure, and its advantages are more significant under extreme space constraints.
Core installation requirements:
Short Rod Nut needs to ensure that the bushing is in the correct direction and the sealing surface is on the movable bushing
Short Forged Nut requires extremely high precision of steel pipe flaring and strict alignment
