Oil Suction Tubes
NTF is the largest producer of Oil Suction Tubes for the Diesel Engine Industry. From one inch diameter through four inch diameter, our tubes include complex bend configurations with welded or brazed flanges and screens.

Turbo Oil Drain Tubes
We produce many configurations of Turbo Drain Tubes with brazed on or welded, metal and powdered metal flanges.

Coolant Tubes
A variety of Coolant Tube designs are being produced throughout our plant. Several designs call for 300 series stainless steel tubing for sea water transfer.

Air Tubes
Diesel Engine compressor inlet and outlet air tubes bent in any configuration are second nature for us. Typically these are powder or e-coated and ready for direct assembly on the engine.

Fuel Rails & Injection Tubes
Our high pressure and low pressure injection lines and fuel rails with compression or brazed-on end fittings are providing the fuel for today’s diesel power plants.

Oil Fill Tubes
Most of our fill tubes include wide outside diameter expansion of the metal creating a funnel type end configuration. Our in-line tube expanders are exceptional for this process.
