Detailed Product Description

This hose assembly is engineered to handle the demands of automotive air conditioning systems using R134-a refrigerant. The combination of aluminum and rubber materials provides a balance of strength and flexibility, reducing the risk of leaks or damage under pressure. The included slimline washer O-rings ([24404] and [24402]) ensure a tight seal at connection points, while the muffler and manifold components help minimize noise and vibration during operation. Both discharge and suction ends utilize P-nut fittings, facilitating straightforward installation and compatibility with the vehicle's existing A/C system. Note that this assembly does not include fittings, brackets, or service ports, so it is intended for applications where those components are already present or separately sourced.
