Crack Detection Group Cap Orifice Caterpillar 3997933

The Crack Detection Group Cap Orifice monitors the performance of diesel particulate filters by measuring soot leakage. It provides a secure fitting to maintain proper flow during crack detection tests, ensuring accurate results. Fits 4-inch exhaust systems, this orifice helps detect potential cracks or leaks in the diesel particulate filters, preventing unfiltered exhaust emissions from bypassing the filter. Attributes:• Provides consistent performance across varying exhaust pressures.• Ensures proper exhaust flow restriction during testing.• Supports accurate monitoring of soot accumulation.Applications: The Crack Detection Group Cap Orifice is used within the diesel particulate filters system, positioned downstream in the exhaust system to measure soot leakage and restrict exhaust flow during crack detection tests.
