45° Elbow Hose Studs - Automatic Lubrication System High-Pressure Fittings

Our Metric 45° Elbow Hose Studs are engineered as premium, solder-free connection elements designed to navigate complex spatial angles and connect high-pressure grease hoses to downstream pipe lines within an automatic lubrication system. Featuring a precise 45-degree bend configuration, these specialized fittings eliminate sharp or restrictive tube routing loops, preventing line kinking and premature hose wear in tight structural areas. Used alongside heavy-duty screw sleeves, these 45° elbow hose ends establish a solid, leak-free mechanical joint that maintains uninterrupted lubricant distribution under intense system operating pressures.

As a prominent high-volume B2B manufacturer and global OEM supplier, we deliver professional-grade accessories for lubrication systems engineered for severe industrial service. To meet diverse environmental and chemical resistance requirements, our 45° elbow hose studs are produced in high-strength galvanized steel, black chromated steel, or exceptional marine-grade Stainless Steel (VA 1.4401 / 316 / V4A).

Core Technical Blueprint & Fitting Integration

• Universal High-Pressure Hose Sizing: Built to seamless dimensional standards, our 45° angled tube studs are cross-compatible with the industry's most common core hose layouts, matching diameters of 4.1 x 8.75 mm, 6.3 x 11.3 mm, and 1/8" x 5/16".

• Targeted Fitting System Configurations: To integrate perfectly with your existing hardware manifolds, our 45-degree studs are precision-machined in two specific boundary profiles:

  • Plain Design (Without Groove): Formulated for standard cutting ring fittings (DIN 2353 / ISO 8434-1) where the internal cutting ring bites directly onto the smooth steel outer diameter.

  • Grooved Design (With Groove): Built explicitly for push-in quick connectors, allowing the internal claws of the push-in block to lock onto the stud groove for rapid, tool-free installation.

Assembly Instructions & Compliance Standards

• Anti-Loosening Assembly Design: The high-pressure connection relies on a dual-threaded interlocking process. The external screw sleeve is first wound onto the outer jacket of the high-pressure hose. The 45° elbow hose stud is then inserted and threaded securely into the screw sleeve body. The screw sleeve utilizes a dedicated left-hand thread internally, which mechanically prevents the sleeve from backing off or loosening from the flexible hose while the 45° hose stud is being tightened home.

• Global Interchangeability: Engineered to exact global dimensional benchmarks, our 45° elbow hose studs offer reliable, drop-in compatibility with hardware lines from all major manufacturers of central lubrication units. They serve as the trusted default choice for smooth angular clearance in commercial truck chassis, wind turbine pitch bearings, articulation joints on heavy mining machinery, and progressive feeder block manifolds.
