CUMMINS
This complete series of external thread pipe joints covers straight threaded fittings (3059308, 3063164, 3406907) and bent threaded elbow fittings (129859, 200293, 3052956, 3819721, 4022705), which are professional pipeline connection accessories specially matched for Cummins M11 diesel engines. These threaded pipe fittings are widely applied to engine fuel pipelines, lubricating oil circuits, cooling pipelines and air intake systems, undertaking pipeline docking, steering connection and sealing fixation functions. They effectively solve common pipeline faults such as interface leakage, poor sealing, thread slipping and pipeline loose connection caused by aging, worn or deformed old pipe joints, ensuring stable and unobstructed operation of Cummins M11 engine fluid and gas circulation systems.

1. High-Strength Alloy Steel Material: All fittings adopt integrated forging alloy steel structure, with high hardness, strong compression and impact resistance. They will not crack or deform under long-term pipeline pressure and engine vibration.
2. Precision Thread Cutting Process: Standard external thread precision machining with smooth and neat thread teeth, accurate tolerance and tight meshing. Effectively avoid thread slipping, tooth skipping and loose connection, ensuring locking stability.
3. Excellent Sealing & Anti-Leakage Performance: Flat and smooth fitting connection end face, matched with standard assembly structure, achieves full-circle tight sealing. Prevent fuel, lubricating oil and gas leakage in engine pipelines.
4. High & Low Temperature Resistance: Stable mechanical performance in extreme environment of -40℃ to +135℃. No thermal deformation and sealing failure under engine high-temperature operation, no brittle cracking in low-temperature working conditions.
5. Oil & Corrosion Resistance: Professional surface passivation and anti-oxidation treatment resists long-term erosion of diesel, engine oil, coolant and humid air, avoiding rust and corrosion failure.
6. Diversified Specification Matching: Straight and elbow dual structural designs meet multi-angle and multi-straight-line docking requirements of Cummins M11 engine complex pipelines, fully adapting to various pipeline installation positions.
7. Strict Factory Quality Inspection: All pipe fittings pass thread precision detection, pressure resistance test and sealing tightness test, with stable batch quality for engine overhaul, daily maintenance and fleet bulk procurement.
