Product Details

Four Seasons Hose Assembly 55100 is built as an OE replacement discharge and suction line for select 1995 Buick, Oldsmobile, and Pontiac vehicles. The hose assembly uses aluminum and rubber sections to match factory routing requirements, and it includes the service port, switch port, seals, and O-rings needed for the refrigerant connection points. This part is specified for R134a systems and uses dual O-ring female O-ring ends on both sides of the assembly. This part cross-references UAC HA10438C for the same application.

Common A/C Problems This Part Can Address

• Refrigerant loss from cracked or leaking hose sections
• Damaged or worn hose connections at the discharge or suction ends
• Faulty service-port sealing at the R134-A quick disconnect connection
• Leaks at O-ring or gasket interfaces in the HVAC line
• Restricted or compromised refrigerant flow through a deteriorated hose assembly

Installation Notes and Tips

Verify the vehicle’s refrigerant system is set up for R134a before installation. Inspect mating surfaces, replace worn seals as needed, and confirm the switch port and service port locations match the original routing on the vehicle. Because fittings are not included, reuse or source the correct vehicle-specific fittings as required by the application. Confirm fitment for 1995 Buick LeSabre, Buick Park Avenue, Oldsmobile 88, Oldsmobile 98, or Pontiac Bonneville before service.
