Product Role & Advantages

The Cummins OEM Piston Cooling Nozzle 3687058 is a precision-engineered component that delivers a controlled stream of engine oil to the underside of each piston. This targeted cooling prevents excessive thermal expansion, reduces crown temperatures, and minimizes risks of scuffing or seizure during high-load operation.

Volgen Power supplies genuine Cummins nozzles, ensuring exact flow rates, perfect alignment, and long-term resistance to clogging or deformation.

Critical Benefits

• Effective Thermal Management — Direct oil spray lowers piston temperatures for improved durability under extreme loads
• Reduced Wear & Friction — Continuous lubrication extends piston, ring, and liner life
• Precise Oil Delivery — Factory-calibrated jet ensures optimal volume without wasting oil pressure
• High-Pressure Resistance — Robust construction handles modern high-output engine demands
• Easy Block Integration — Press-fit or bolted design for straightforward replacement during overhauls

Engine Compatibility

Designed for Cummins 15-liter platforms:

• ISX15 (CM2250, CM2350, EPA10 and later)
• QSX15 (industrial and off-highway ratings)
• X15 (Efficiency and Performance series)
• Related Signature and heavy-duty variants

Common in mining trucks, generator sets, marine propulsion, construction equipment, and long-haul tractors.
