I.D. to I.D. connectors
Compare both listed inside diameters with the pipe ends being joined. These connectors are available in selected aluminized and chrome options.
Semi-Truck Exhaust Connectors & Sleeve Inserts
Compare aluminized and chrome exhaust connectors, plus elbow connector sleeve inserts, in listed 5-, 6- and 7-inch sizes. Match the I.D. and O.D. measurements at both ends to your truck’s exhaust components.
Choose the connection type before selecting a finish. Check the product’s dimensions, pipe-end configuration and required clamps or supports to confirm the right fit for your exhaust setup.
Choose the Right Exhaust Connection
I.D. to O.D. connectors
Match the inside-diameter end and outside-diameter end separately. The same nominal size does not make every pipe-end configuration interchangeable.
Elbow sleeve inserts
Check the insert specified for the plain-bottom exhaust and elbow connection. Confirm the listed size and how the adjoining parts fit together.
Before ordering: Measure both pipe ends, identify I.D. versus O.D., and check the connector’s dimensions and included parts. Select compatible clamps and supports for the complete assembly.
Exhaust Connector FAQs
What do I.D. and O.D. mean on an exhaust connector?
I.D. means inside diameter; O.D. means outside diameter. These identify different surfaces of the pipe. Check both ends of the connector and the adjoining components rather than choosing by the nominal inch size alone.
What is the difference between I.D.-to-I.D. and I.D.-to-O.D. connectors?
An I.D.-to-I.D. connector has openings described by their inside diameter at both ends. An I.D.-to-O.D. connector has one end described by its inside diameter and the other by its outside diameter. Match that end configuration to the pipes or components you are joining.
Which exhaust connector sizes are available here?
This category lists 5-, 6- and 7-inch options. The available finishes and end configurations vary by size, so check the individual product title and specifications before ordering.
Should I choose an aluminized or chrome exhaust connector?
The aluminized connector listings specify aluminized steel, while the chrome connector listings describe chrome-plated steel. Choose the required size and connection type first, then compare the finish and care requirements for the installation.
What is an exhaust elbow connector sleeve insert used for?
The sleeve insert listings describe connections between a plain-bottom exhaust section and an elbow pipe. These are listed separately from the standard I.D.-to-I.D. and I.D.-to-O.D. connectors. Confirm the stated pipe sizing and connection arrangement for the exact insert.
Are exhaust clamps included with the connector?
The product listings describe one connector or sleeve insert in the included-parts section. Review the exact listing and arrange any compatible clamps, supports or other hardware required for your exhaust assembly.
Will these connectors fit any Peterbilt, Kenworth or Freightliner?
Fitment depends on the exhaust components’ dimensions and connection arrangement. Measure the existing pipe ends and compare the product specifications; the truck brand alone does not establish compatibility.
