8108100E51LU AC Compressor Suction Pipe is the low-pressure refrigerant hose connecting evaporator outlet and compressor inlet on JAC HFC1048 light truck air conditioning circuit. It delivers cool gaseous refrigerant back to the compressor for compression cycle, wrapped with thermal insulation layer to reduce heat absorption and guarantee cooling efficiency. This aftermarket replacement hose fixes refrigerant leakage, insufficient cooling output and frost on pipe surface caused by rubber aging, outer layer cracking and joint seal failure of old pipes. Stable refrigerant circulation keeps cab cooling performance for light trucks operating under high-temperature delivery conditions.

Product Advantages Inner rubber tube resists erosion from R134a refrigerant and compressor oil. Reinforced fiber braid layer improves burst pressure and anti-expansion performance under working pressure. External foam insulation sleeve minimizes heat gain from hot engine compartment. Each hose undergoes air tightness and pulsating pressure test before shipment, molded bending shape and original quick connectors for direct fitment without extra modification.

Applicable Models Fit for JAC HFC1048 series light-duty commercial trucks, widely used for city distribution and short-haul cargo transport.

FAQ

Q1: What symptom indicates this suction pipe has refrigerant leakage?
A1: Gradually weaker cold air, oily residue around joint and continuous loss of refrigerant.
Q2: Why should technicians check the O-rings at both ends while replacing the AC hose?
A2: Aging sealing rings are common leakage points and must be replaced together to avoid rework.
Q3: What installation precaution can prevent early damage to the new suction hose?
A3: Reserve enough clearance away from hot exhaust parts and moving pulleys to avoid friction and heat burn.
