The DIN 2353 / ISO 8434-1 LL Series Straight Male Stud Fitting is specifically engineered for low-pressure fluid systems, compact spaces, and pneumatic applications. Utilizing a standardized 24° internal cone, this bite-type connector provides a lightweight yet secure, vibration-resistant joint for small-diameter metric tubing.
As an established global OEM and wholesale supplier, our manufacturing plant deploys state-of-the-art CNC precision equipment. Every production run is subjected to rigid material-integrity tests to satisfy the stringent requirements of international industrial standards. This straight male connector bridges metric tube assemblies directly to component ports using specialized tapered threads designed to seal securely on the flanks.

Core Technical Blueprint & Tapered Thread Configurations
The LL Series Edge: The Extra Light (LL) Series is designed for optimized spaces and standard low-pressure environments up to 100 bar (for tube Outer Diameters from 4mm to 12mm). It provides a compact structural profile without compromising sealing performance.
Flank-Sealing Tapered Threads: To accommodate diverse international plumbing layouts, this series is manufactured with three specific thread profiles that achieve a tight seal through metal-to-metal thread interference:
Metric Taper Thread: Follows international metric standards for seamless integration into European-built machinery and compact manifolds.
BSPT Taper Thread (British Standard Pipe Taper): Engineered with a 55° thread angle for compatibility with global industrial piping systems.
NPT Taper Thread (National Pipe Taper): Engineered with a 60° thread angle, meeting North American requirements for instrumentation and process control lines.
Application & Compliance
Bite Type Sealing: Upon tightening the compression nut, the single-edge cutting ring reliably grips the outer diameter of the tube. This action creates a strong, leak-free mechanical seal that resists vibration and system pulses.
Traceable Compliance: Fully compliant with ISO 8434-1 and DIN 2353 standard dimensions, making these fittings fully interchangeable with high-performance global systems. They are the ideal choice for automotive lines, laboratory instrumentation, pneumatic control panels, and light hydraulic machinery.
