The HPT 500 High-Pressure Diagnostic Leak Tester from Bosch offers leak detection for large commercial vehicles.

HPT 500 produces a large volume of smoke that is necessary for systems on large commercial vehicles. The machine delivers smoke at up to 30 p.s.i., producing higher pressures than standard machines and simulates truck boost to safely test with the engine off.

The device was designed with a durable construction and is capable of testing an entire system in 15 minutes. The HPT 500 is aimed at testing and finding leaks in exhaust aftertreatment systems in medium-and heavy-duty vehicles.

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, 100-240-volt AC plug, and a hex key. The housing is constructed of steel and billet aluminum for durability and extended service life.
