What This Hose Does
This is a charge air cooler connector hose. It sits between the turbo outlet piping and the cooler, or between the cooler and the intake, and it has to seal hot pressurized boost air without collapsing or ballooning. The hump in the middle absorbs engine movement and pipe misalignment so the clamp joints aren't fighting the frame every time the chassis flexes.
Construction is silicone with two stainless steel rings embedded in the wall. The rings keep the hose from ballooning under boost and stop the hump from folding in on itself under vacuum or when a clamp is pulled down hard. Silicone handles the heat cycling near the charge air plumbing better than the rubber hoses that used to go in these positions.
Size is 2.5 inch inside diameter by 5 inches long. Both ends are straight beads for standard T-bolt or constant-torque clamps. Measure the pipe your old hose came off before ordering — 2.5 inch tube is common on this plumbing but nearby joints on the same truck can be a different diameter.
Why These Numbers Cross
Cummins lists F02487S352 for this position. PartStop stocks the same physical hose under 6112001211009. The numbers cross because the parts share the dimensions that matter for a boost joint: 2.5 inch inside diameter, 5 inch overall length, hump profile, and two stainless rings in the wall. Change any one of those and the hose either won't clamp or won't survive boost pressure.
Charge air hoses are dimensional parts, not electronic ones. There's no calibration and no serial matching. If the ID matches the tube, the length matches the gap between beads, and the reinforcement rating is there, the joint works. That's why one aftermarket hose covers a Cummins number used across Agrale and Cummins applications.
The Cummins number is printed here for identification only. PartStop is not affiliated with, endorsed by, or authorised by Cummins or Agrale. Use the cross-reference as a starting point, then confirm against the number stamped or printed on the hose you pulled off, or against your VIN.
Before You Order
Pull the old hose and check it in daylight. Silicone that has gone chalky, hard, or shows fine cracks in the hump has heat-cycled out. Oil-soaked or swollen sections mean a turbo seal or a leaking breather is dumping oil into the charge pipe — replace the hose and find the oil source, or the new one softens the same way.
Measure the tube OD on both sides of the joint with a caliper, not a tape. Then measure bead-to-bead gap. A hose that is short pulls the pipes together and loads the clamps; too long and it bows and rubs. Inspect the clamps too — stretched T-bolts and rounded worm gears are a common cause of repeat blow-offs on charge air joints.
6112001211009 Cross-Reference & Interchange Numbers
These manufacturer and aftermarket numbers commonly cross-reference to 6112001211009. 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.

Frequently asked questions
Will 6112001211009 replace Cummins F02487S352?
It's the aftermarket equivalent for that position and matches on ID, length, hump profile, and stainless ring reinforcement. Cross-reference is a starting point, not a fitment guarantee. Confirm by the number on the hose you removed or by VIN before you order.
What do the two stainless steel rings do?
They're embedded in the silicone wall and hold the hose round. Under boost the rings stop the hose from ballooning at the hump; under vacuum or hard clamp torque they stop it from collapsing inward. An unreinforced hose in a charge air position will distort and eventually blow off the pipe.
How do I know if my CAC hose is the problem?
Symptoms are low boost, derate, and a boost leak code. Pressure-test the charge air system and look for the hump ballooning or the hose walking off the bead at the clamp. Also check for oil inside the pipe — that softens silicone and is a separate problem to chase.
