26791 series is 90° swaged elbow with JIC female swivel nut and 74° cone sealing surface, specially designed for compact hose routing of high-pressure hydraulic systems. Integral hot forging plus precision CNC machining forms dense solid body to resist frequent pressure surge and equipment long-cycle vibration. Free rotating swivel nut realizes angle adjustment before locking and eliminates hose torsion stress during assembly; metal-to-metal 74° cone seal keeps stable leakproof performance under fluctuating pressure and temperature. Two mature anti-corrosion surface treatments fit diversified working media of oil, water and compressed gas, widely used for hose assembly of engineering machinery, metallurgy and offshore equipment to cut later maintenance cost.
Produced strictly in accordance with SAE J514 industrial specification, all JIC thread pitch, 74° cone angle and inner bore dimension are precisely controlled by CNC fine machining. Complete size range matches mainstream multi-layer braided hydraulic hoses, fully interchangeable with world-famous brand equivalent fittings. All finished goods pass factory high-pressure burst and tightness test; complete dimension drawings and parameter sheets can be supplied upon customer request.
360° Free-Rotation Swivel Nut: Smooth rotating swivel nut realizes arbitrary directional alignment before locking, effectively avoiding hose torsion and fatigue crack caused by forced installation.
74° Cone Metal Hard Seal Structure: Precision machined flare cone forms compact metal-to-metal compression seal after standard torque tightening, no extra sealant required and stable leakproof under vibration and fluctuating pressure.
Polished Inner Flow Channel: Burr-free polished inner cavity reduces fluid turbulence and pipeline pressure loss, improving overall hydraulic system operation efficiency.
High-Density Forged Anti-Vibration Body: One-piece hot forging eliminates internal casting porosity, enhances whole compression and fatigue resistance to prevent connector loosening under continuous high-frequency vibration.
Multi-Standard Universal Matching: Standard JIC structure can dock various global mainstream thread specifications with matched adapters, helping customers reduce spare part inventory types.
Environment-friendly trivalent chromium zinc plating with uniform tight coating adhesion and qualified salt spray resistance, high mechanical strength and outstanding cost performance. Ideal for construction machinery, agricultural equipment and general indoor hydraulic hose matching.
Professional deep passivation removes surface free iron and machining impurities to generate compact self-repair anti-oxidation film, excellent acid, alkali and salt fog resistance, perfectly suited for marine, petrochemical and high-humidity severely corrosive working environments.
Construction & Agricultural Machinery: Finished hydraulic hose steering connection for excavators, loaders, tractors and harvesting equipment under outdoor variable working conditions.
Precision Machinery & Metallurgy: Compact pipeline layout and medium diversion for CNC machine tools, automated production lines and metallurgical hydraulic stations.
Petrochemical & Offshore Engineering: Stainless steel version for chemical medium delivery pipeline and offshore platform fluid transmission hose assembly.
General Industrial Hydraulics: High-pressure hose fitting for hydraulic power unit and pneumatic control equipment pipeline routing.
Raw blank is integrally hot forged to rearrange internal metal grain along elbow bending direction for denser texture and higher burst pressure resistance. JIC thread, 74° sealing cone and inner runner are synchronously finished by multi-axis CNC lathe to guarantee micron-level dimensional accuracy. All finished elbows pass thread calibration, hydraulic impulse sealing test and full appearance screening before warehousing to satisfy international standard requirements.
Q1: What’s the advantage of swivel nut design compared with fixed elbow?
A1: After hose crimping, swivel nut rotates independently to adjust installation angle without twisting hose, greatly lowering early hose failure rate caused by assembly torsion stress.
Q2: Can zinc-plated carbon steel be used for long-term outdoor open-air working?
A2: Cr3+ zinc coating realizes reliable anti-rust effect for conventional outdoor engineering and agricultural machinery; select passivated stainless steel for coastal salt fog and chemical corrosion scenarios.
Q3: Can custom laser marking be added on fitting surface?
A3: Yes, we support laser engraving customer’s exclusive brand logo and part number after receiving vector drawing files.
Q4: Can it directly replace imported same-spec JIC swivel elbow?
A4: Produced per unified SAE J514 dimension standard, fully interchangeable with mainstream international brands for direct drop-in replacement without pipeline modification.
Q5: How about medium compatibility for synthetic hydraulic oil?
A5: Base metal is inert to most petroleum and common synthetic hydraulic fluids; customize special sealing parts for highly corrosive synthetic medium on request.
