BT4-7524 Receiver Drier for Motorhome Applications

The BT4-7524 Receiver Drier for Motorhome Applications is built for motorhome A/C and mobile HVAC systems.
It helps remove moisture and debris from the refrigerant circuit.

This steel receiver drier measures 2 1/2 inches in diameter and 6 5/16 inches long.
It uses M18 male O-ring fittings on both the inlet and outlet.

As a result, it is a strong replacement option for compatible GM chassis motorhome A/C systems.

Function and Performance

A receiver drier helps protect the A/C system from moisture and contaminants.
It also supports steady refrigerant flow.

Moisture inside the system can cause poor cooling and corrosion.
In addition, debris can damage the compressor, expansion valve, and other A/C parts.

Therefore, replacing the receiver drier during major A/C service is an important step.
It helps protect the system and supports reliable cooling performance.

Durability and Design

The BT4-7524 receiver drier uses steel construction for mobile HVAC use.
It is designed for R134a refrigerant systems.

This drier includes a top sight glass and a top M10 switch port.
Because of this layout, it supports inspection and control functions in compatible motorhome A/C systems.

It is commonly used in motorhome and GM chassis motorhome applications that match Parker 085722 or PACCAR RV218337.

Installation

Install this receiver drier in the correct direction of refrigerant flow.
Then connect the M18 male O-ring inlet and outlet fittings.

Before ordering, compare your current drier size, fitting style, sight glass location, and switch port.
Also, confirm that your OEM or cross-reference number matches your application.

For best results, replace the receiver drier any time the A/C system is opened for major service.
