Spheros Climate Control 11132577A | A/C Accumulator & Receiver Drier Filter Kit — Heavy-Duty Truck & Commercial Vehicle HVAC
The Spheros 11132577A accumulator and receiver drier kit is a direct OE-specification replacement for heavy-duty truck, transit bus, and specialty commercial vehicle air conditioning systems operating on R134a refrigerant. It traps moisture, acid, and particulate contamination from the refrigerant circuit to protect compressors, expansion valves, and downstream A/C components from wear and premature failure.
Fitting Configuration
Inlet: 3/8" Male Insert O-Ring (MIO) | Outlet: Pad Mount | Refrigerant Type: R134a. This is a hybrid fitting configuration. Verify both inlet and outlet fitting types against your vehicle's service documentation before installation to confirm compatibility.
When to Replace
The receiver drier should be replaced every time the refrigerant circuit is opened for service, regardless of the reason. Once exposed to atmosphere, desiccant absorbs moisture rapidly and loses capacity. Most A/C compressor warranties require proof of drier replacement as a condition of coverage. Replacing this kit at each service event is standard practice in fleet and transit maintenance programs.
