Bosch Introduces New High-Pressure Leak Tester For Heavy-Duty And Turbocharged Applications

WARREN, Mich. – Bosch recently introduced the new HPT 500 High-Pressure Diagnostic Leak Tester for North America, offering high-pressure diagnostic leak detection for heavy-duty vehicles and turbocharged passenger cars.

The HPT 500 provides a solution for HD vehicle diagnosis and repair by producing a larger volume of smoke necessary for these larger systems. The machine delivers leak-detection smoke at up to 30 psi – producing higher pressures than standard machines – and simulates truck boost to safely test with the engine off, according to Bosch.

The HPT 500, which debuted at the 2017 TMC Meeting & Exhibition, will be available in North America in April.

Capable of testing an entire system in 15 minutes, the machine can help technicians diagnose leaks faster. The HPT 500 is an ideal solution for testing and finding leaks in exhaust after-treatment systems in medium- and heavy-duty vehicles, according to Bosch.

With dual operating modes, technicians can alternate between smoke-only and air-only cycles to confirm repairs. The machine also features a flow-control valve, remote shut-off, a flow-rate gauge and system-pressure and test-pressure gauges.

The Bosch HPT 500 High Pressure Leak Tester includes a bottle of vapor-producing fluid, remote control key fob, 100-240V AC plug and a hex key. The housing is constructed of steel and billet aluminum for durability and extended service life.

For a technician or fleet owner looking to service smaller HD fleets and medium-duty applications, the HPK 200 accessory kit can adapt the HPT 500 to meet those needs. The accessory kit includes:
