CLAMPS & BRACKETS

Clamps & Accessories For Peterbilt Trucks

Clamps are workhorses of the heavy-duty truck — used throughout exhaust, intake, coolant, air, and hydraulic systems to seal connections and secure hoses, pipes, and ducting under the heat and vibration of Class 8 operation. A failed clamp can mean a coolant leak on the highway, an exhaust leak at the turbo outlet, or a boost pressure drop at the charge air cooler — all of which can quickly escalate into serious engine or downtime events. We carry band clamps, T-bolt clamps, and specialty clamps sized for the specific connections found on Peterbilt trucks.

Frequently asked questions about clamps & accessories

What is the difference between a band clamp and a T-bolt clamp for exhaust connections?

Band clamps (also called V-band or lap-joint clamps) use a flat or formed band tightened by a single bolt to compress a slip joint or flanged connection — they are common on exhaust flex connections and stack couplings where disassembly is routine. T-bolt clamps use a T-shaped bolt and a solid band to generate high, uniform clamping force around a hose or pipe — they are preferred on high-pressure, high-vibration connections like turbo inlet hoses and charge air cooler connections where a standard worm gear clamp would be insufficient. Using the correct clamp type for the application matters significantly for sealing performance and service life.

How do I select the right clamp size for my Peterbilt's exhaust or intake system?

Clamp sizing is based on the outside diameter of the pipe, hose, or connection being clamped. For exhaust stack and outlet connections on Peterbilt trucks, common diameters include 4", 5", and 6". For intake and turbo connections, measure the hose OD at the clamping point — charge air hoses on PACCAR MX and Cummins X15 engines typically range from 3" to 5" depending on the connection location. Always measure before ordering, as nominal pipe sizes can vary from actual OD by enough to affect clamp fit and sealing.

How often should exhaust and intake clamps be inspected on a Peterbilt?

Clamps on exhaust and intake systems should be inspected at every PM interval and any time exhaust leaks, boost loss, or intake noise is suspected. Heat cycling causes metal clamps to expand and contract repeatedly, which can loosen hardware over time — particularly on flex pipe connections near the turbocharger. Torque clamps to specification on reassembly, and replace any clamp showing cracks, corrosion through the band, or stripped bolt threads rather than attempting to retighten damaged hardware.
