Baldwin Filters AFG37R Air Filter Restriction Gauge

The Baldwin Filters AFG37R is a body repair tool designed for monitoring air filter restriction in automotive and industrial applications. It provides a direct visual indication of filter condition so technicians can schedule maintenance before performance drops. The gauge suits workshops and fleet operators who need a simple, mechanical way to track filter life without electronic sensors.

Includes 1/8-27 NPT Fitting

The kit supplies a 1/8-27 NPT fitting, a 1/4 in OD by 10 ft coiled EPDM hose and a coupling so the gauge can be plumbed directly into the filter housing. Mounting screws are also provided for permanent installation on equipment panels. These bundled parts remove the need to source separate fittings or hose, letting the installer complete the job in a single visit.

Plastic Body Limits High-Temperature

The gauge body is made from plastic, which restricts its use to environments where temperatures and pressures stay within the material's mechanical limits. It is not suited for extreme heat, aggressive chemicals or vibration-heavy mounts that could crack the housing. Installers should verify that the operating conditions of their specific engine or compressor fall inside the plastic body's safe range before fitting the gauge.

Questions about this item

Will the plastic gauge body or the EPDM hose need replacement first?

The gauge body is plastic and the hose is EPDM; both are included new so replacement timing depends on service conditions.

What fitting limits installation on a filter housing?

Installation uses the included 1/8-27 NPT fitting, which must match the housing port thread.

How hot does the coiled hose get during continuous engine operation?

The 10 ft EPDM hose is rated for typical engine bay temperatures; no specific sustained-heat limit is published.
