CALL THE MANUFACTURER
School Bus Exhaust Accessories
Auto-jet manufactures and stocks the hardware that holds an exhaust system together. Clamps, hangers, brackets, gaskets and adapters, most of it cross-brand, sized to fit rather than matched to a single model. If you know the diameter and the material you need, the part is here. If you are working from an OE number, call and we will cross it.
Band Clamps, V-Clamps and Sleeves
Band clamps in stainless and aluminized, sized by pipe diameter. V-band clamps for DPF and DOC connections, including T-bolt styles. Sleeves for slip joints. Clamp fitment is by diameter and material, so measure the pipe rather than looking up the bus.
Auto-jet stocks clamps across the full catalog, not only the accessory line. Search the complete clamp listing on the parts catalog.
Hangers and Mounting Brackets
Pipe hangers, muffler hangers and mounting brackets for school bus exhaust. Sized by pipe diameter and mounting pattern. Several are specific to a chassis and engine combination, so confirm the application before ordering.
DPF and DOC Hardware
Body gaskets and V-band clamps for diesel particulate filters and oxidation catalysts, covering Cummins, Paccar, Volvo and Mack applications. These are service parts, replaced when the filter comes off.
Call 800-247-5391 to confirm the gasket matches your filter body.
Cat's Eye Tire Pressure Systems
Auto-jet also supplies Cat's Eye tire pressure equalization systems for dual-wheel applications. Available in 5 PSI increments across the standard school bus range, with a wheel-mount and a hub-mount bracket option. This is tire equipment, not exhaust, and it is listed here because it is cross-brand fitment like the rest of this page.
Frequently Asked Questions
How do I size a band clamp?
By the outside diameter of the pipe it clamps, and by material. Auto-jet stocks stainless and aluminized in the common school bus diameters. Measure the pipe rather than working from the bus model.
Do these fit more than one bus brand?
Most of them. The majority of the accessory line carries no single brand assignment because clamps, hangers and gaskets are sized parts. Where a bracket is chassis-specific, the part record says so.
Can you cross an OE number on an accessory?
Sometimes. Fewer accessory parts carry an OE cross-reference than exhaust components do, because they are sized rather than model-matched. Call our team with the number and we will check it against the catalog.
