Straight Hose Stud JIC Swivel Connector - Auto Lube System High-Pressure Fittings

Our Metric Straight Hose Stud JIC Swivel Connector is engineered as a premium, solder-free connection element designed to bridge flexible high-pressure grease hoses directly to 37-degree flared male adapter ports within your auto lube system. Featuring a precision-crimping hex swivel nut on one side and a robust hose insert tail on the other, this heavy-duty adapter allows technicians to secure or detach high-pressure lines easily without twisting or rotating the entire flexible hose body. It ensures an unyielding mechanical connection that eliminates twisting stress, prevents structural leakage, and coordinates seamless lubricant routing to progressive distribution blocks.

As an established high-volume B2B manufacturer and global OEM partner, we construct our auto lube system components on automated multi-axis precision lathes to guarantee flawless internal boring, tight concentricity profiles, and exact thread tolerances. To satisfy diverse environmental and chemical resistance requirements, our straight JIC swivel hose connectors are produced from high-strength galvanized steel, black chromated steel, or exceptional marine-grade Stainless Steel (VA 1.4401 / 316 / V4A) to withstand aggressive corrosion and intense machine vibration cycles.

Core Technical Blueprint & Fitting Integration

• Universal High-Pressure Hose Sizing: Built to exact global dimensional tolerances, our JIC swivel hose studs are fully cross-compatible with the industry's most common core hose layouts, accommodating diameters of 4.1 x 8.75 mm, 6.3 x 11.3 mm, and 1/8" x 5/16".

• SAE J514 / ISO 8434-2 Compliance: The swivel coupling head features an industry-standard 37° internal flare seat matching standardized unified thread dimensions (UNF/UNEF).

  • Flawless Metal-to-Metal Seal: When threading the female swivel nut onto a matching male JIC stud adapter, the internal 37-degree seat profile forms an airtight, metal-to-metal mechanical seal. This eliminates the need for liquid thread sealant, thread tape, or rubber elastomeric rings, making it completely reliable under high-stress thermal expansion and pulsing industrial pressures.

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 JIC swivel hose stud tail 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 straight hose stud is being tightened home.

• Global Interchangeability: Engineered to meet standard international configuration rules, our straight hose stud JIC swivel connectors offer complete, drop-in compatibility with hardware lines from all major manufacturers of central lubrication units. They serve as the trusted default choice for commercial vehicle chassis, wind turbine pitch bearings, articulation joints on heavy mining machinery, and progressive feeder block manifolds.
