Bosch releases HD smoke machine bladder adapters

Updated May 17, 2019

Bosch has introduced five new bladder adapters in North America for its HPT 500 heavy-duty smoke machine. The adapters seal off various-sized pipes and hoses when checking for leaks and range in size from 1.5 to 5.9 in. Each bladder expands to completely seal hoses and pipes in exhaust, intake and turbocharging systems so they can be filled with smoke to check for leaks, according to an announcement.

The bladders are used with the HPT 500 High-Pressure Diagnostic Leak Tester, offering high-pressure diagnostic leak detection for heavy-duty vehicles and turbocharged passenger cars. HPT 500 provides a solution for heavy-duty 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 20 psi, producing higher pressures than standard machines and simulates truck boost to safely test with the engine off.

The newly available adapters are:

  • 169500006 1.5-in. adapter
  • 169500007 1.9-in. adapter
  • 169500008 2.9-in. adapter
  • 169500009 3.9-in. adapter
  • 169500010 5.9-in. adapter

The HPT 500 is capable of testing an entire system in 15 minutes and can help technicians diagnose leaks faster in exhaust after-treatment systems in medium- and heavy-duty vehicles, the company says.

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.
