90° Elbow Hose Stud Pipe Socket - Automatic Lubrication System High-Pressure Fittings

Our Metric 90° Elbow Hose Stud Pipe Sockets are engineered as premium, solder-free connection elements designed to navigate compact right-angle turns and link high-pressure grease hoses to downstream block ports within an automatic lubrication system. Featuring a sharp, precision-bent 90-degree configuration, these specialized pipe sockets completely eliminate wide, sweeping tube routing loops, preventing line pinching, friction wear, and premature hose fatigue in space-restricted areas. Used alongside heavy-duty screw sleeves, these 90° 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 90° elbow hose stud pipe sockets 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 90° right-angle pipe socket 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 90-degree pipe sockets 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 of the socket extension.

  • 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 90° 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 90° pipe socket is being tightened home.

• Global Interchangeability: Engineered to exact global dimensional benchmarks, our 90° elbow hose stud pipe sockets offer reliable, drop-in compatibility with hardware lines from all major manufacturers of central lubrication units. They serve as the trusted default choice for clean right-angle clearance in commercial truck chassis, wind turbine pitch bearings, articulation joints on heavy mining machinery, and progressive feeder block manifolds.
