An Air Conditioner Lines Splined Adapter connects the air conditioning unit's piston pump to the power transmission shaft. It uses a splined interface to ensure secure torque transfer without slippage. This adapter allows smooth and efficient rotation of the piston pump under different load conditions.Attributes:• High torque transmission capability.• Ensures smooth rotational transfer to the piston pump.• Maintains alignment under dynamic load.Applications: An Air Conditioner Lines Splined Adapter is installed is located between the air conditioning piston pump and the drive shaft, to serve as a coupler, transferring engine-generated rotary motion to the pump’s internal piston mechanism.
