About DELEYAPARS

DELEYAPARS supplies aftermarket heavy equipment parts and related electrical replacements for construction, agriculture, automotive, and industrial equipment—plus pool and spa heater controls. Buyers match replacements by the OEM part number on the failed unit. Parts are aftermarket compatible replacements, not factory-original OEM.

Sensors — temperature sensors, pressure sensors, speed sensors, throttle position sensors (TPS), intake air pressure (MAP), mass air flow (MAF), liquid level, and related sensor types under the main Sensors collection.

Valves & solenoid valves — fuel and control solenoid valves, oil control valves (VVT), suction control valves (SCV), turbo boost and vacuum solenoid valves, hydraulic and cartridge valves, and other valve types.

Fuel shut-off & engine stop solenoids — 12V/24V stop solenoids used to cut or hold fuel on diesel equipment.
