Our Metric Straight Hose Studs are engineered as premium, solder-free connection elements designed to link high-pressure grease hoses directly to downstream pipe lines within an automatic lubrication system. Used in tandem with heavy-duty screw sleeves, these high-pressure straight hose ends establish a solid, leak-free mechanical joint without the need for welding or specialized flaring tools. They ensure uninterrupted, high-pressure lubricant flow through demanding distribution loops, keeping vital machine bearings running smoothly.
As a high-volume B2B manufacturer and global OEM partner, we supply premium accessories for lubrication systems crafted to survive severe machinery environments. Our straight hose studs are available in high-strength galvanized steel, black chromated steel, or exceptional marine-grade Stainless Steel (VA 1.4401 / 316 / V4A) to withstand aggressive environmental corrosion and intense vibration cycles.

Core Technical Blueprint & Fitting Integration
Universal High-Pressure Hose Sizing: Optimized for multi-brand compatibility, these straight tube studs precisely fit the industry's most common core hose dimensions, including 4.1 x 8.75 mm, 6.3 x 11.3 mm, and 1/8" x 5/16" layouts.
Targeted Fitting System Configurations: Depending on your system design, our straight hose ends are manufactured in two precise variations to integrate perfectly with your hardware blocks:
Plain Design (Without Groove): Engineered specifically for heavy-duty cutting ring fittings (DIN 2353 / ISO 8434-1) where the internal cutting ring bites directly onto the smooth outer diameter of the steel stud.
Grooved Design (With Groove): Built explicitly for push-in quick connectors, allowing the internal locking claws of the push-in block to click directly onto the matching stud groove for rapid tool-free installation.
Assembly Instructions & Compliance Standards
Anti-Loosening Assembly Design: The connection process uses a smart mechanical layout. First, the screw sleeve is wound onto the high-pressure hose outer jacket. Subsequently, the straight tube stud is threaded internally directly into the screw sleeve body. The screw sleeve utilizes a dedicated left-hand thread internally, which prevents it from backing off or loosening from the main hose while the straight hose stud is being tightened home securely.
Global Interchangeability: Engineered to meet standard global dimensions, our straight hose studs offer seamless, drop-in compatibility with lines from all major manufacturers of central lubrication units. They are the preferred selection for heavy commercial truck chassis, wind generator main bearing housings, high-stress mining gear, and progressive feeder block plumbing circuits across the manufacturing sector.
