Vehicles: Commercial trucks, buses, transit fleets, and Holset QE compressor applications
• Voltage: 12V

Applications: Designed for air brake systems using Holset QE compressors and Model 9 dryer configurations with integrated drop-in line 5000457. In a 4-line setup, the added loop line maintains pressure balance in the compressor discharge line during unloaded operation by routing air from the delivery side of the dryer back to the supply side. This helps prevent vacuum formation above the compressor piston, reduces oil carryover risk, and helps protect brake system components.
