What You're Actually Buying
This is a 4-inch to 6-inch silicone hump hose, meaning it steps down (or up) between two different pipe diameters while still flexing enough to handle engine movement and vibration on the cold side of your charge air cooler piping. Three wire reinforcement rings molded into the silicone keep it from collapsing under vacuum or ballooning under boost pressure.
Volvo and International both spec'd this same hose geometry across a chunk of their truck lineups, which is why one part number covers both nameplates. It's not because someone slapped a sticker on it - the hose itself is identical where the OEM engineers landed on the same fitment.
Cold side CAC hoses take a beating from heat cycling and road grime even though they're not carrying the hottest air in the system. If yours is cracked, hard, or has a chunk missing near a clamp, don't wait for it to blow on the highway.
How the Cross-Reference Numbers Line Up
8072886 is the number you'll see stamped on Volvo trucks, and it cross-references to International's own 3625343C1 because Navistar used this hose on their equipment too. Aftermarket suppliers list it as D50-6039 or F01612S352 - same hose, different box.
The reason these numbers all point to the same part is dimensional: 4-inch and 6-inch ends, overall length, and three-ring reinforcement pattern all have to match for the hose to seat right and clear surrounding components. If any of those specs are off even slightly, you'll fight it during install or it'll leak boost within a few months.
Don't go by memory or by what's on the truck next to yours in the yard. Pull the number off your old hose or run your VIN before you order. Trim levels, engine options, and mid-year running changes can put a different hose on trucks that otherwise look identical.
Ordering From PartStop
We're in Tacoma and keep this hose in stock, so if you're local you can grab it same-day and get the truck back on the road instead of waiting on freight. If you're not local, we ship nationwide and most orders move quick enough that you're not parking equipment any longer than you have to.
This is aftermarket silicone, not a Volvo or Navistar-branded box, and we're not going to tell you it's identical to factory - it's not sold as that and we don't market it that way. What we will tell you is it's built to the same dimensions and comes with a 6+ month warranty, so if something's off, you're covered.
Confirm the number on your old hose before you check out. Hump hoses look similar across a lot of applications, and a 4x6 that's an inch short on either end will not seal no matter how hard you clamp it.
8072886 Cross-Reference & Interchange Numbers
These manufacturer and aftermarket numbers commonly cross-reference to 8072886. Use them to identify the part — then confirm the exact fit by VIN or the number stamped on your old unit before you order. An interchange is a starting point, not a fitment guarantee.
| Brand / Line | Cross-Reference Numbers |
|---|---|
| International | 3625343C1 |
| Aftermarket | D50-6039, F01612S352 |
Frequently asked questions
Does 8072886 fit my International truck?
It cross-references to International's 3625343C1 and covers a number of Navistar applications, but engine and CAC configuration can change what hose a specific truck needs. Pull the number off your old hose or check your VIN before ordering to be sure.
Is this the same as International part 3625343C1?
They interchange - same hose dimensions, same three-ring reinforcement, same fitment points. Volvo and International just each assigned their own part number to what is functionally the same hump hose.
What's actually failing when this hose needs replacing?
Usually it's the silicone cracking or going brittle from heat cycling, or a split forming right at one of the reinforcement rings. Check for boost leaks, visible cracks, or soft spots when you're doing routine inspections.
