Metric Straight Bulkhead Female Fitting with Grease Nipple - Automatic Lubrication System Couplings

Our Metric Straight Bulkhead Female Fitting with Grease Nipple is the industry standard for distributing lubricants safely through high-frequency automated lubrication networks and your commercial automatic lubrication system. Specially engineered for BEKA-MAX or equivalent heavy-duty progressive lubrication environments, this specialized panel connector features an elongated center section, a dedicated heavy-duty panel locknut, an internal female port, and an integrated, high-durability thread-in grease nipple. By anchoring lines directly through physical structural partitions, it establishes a reliable external manual fill port or backup lubrication point that connects seamlessly to your internal automated tubing lines.

As a high-volume B2B manufacturer and global OEM supplier, we construct our automatic lubrication system fittings on automated multi-axis precision lathes to guarantee flawless internal boring, perfect concentricity, and exact thread pitches. Every production lot is subject to rigorous quality control auditing to ensure absolute structural stability and a leak-free seal under the severe, pulsing pressures common in automated lubrication networks.

Core Technical Blueprint & BEKA-MAX Engineering

• Optimized for LL Series Networks: Purpose-built for the Extra Light (LL) Series footprint, this straight female bulkhead coupling handles operating thresholds up to 100 bar, aligning seamlessly with the pressure boundaries of a modern automatic lubrication system (machined for small-diameter tubing from 4mm to 12mm). Its minimized mass and extended exterior thread section ensure clean, flat mounting inside crowded machinery panels, truck frames, and heavy-equipment chassis channels.

• Integrated Backup Grease Nipple Interface: The external bulkhead face provides a clean internal female thread path pre-assembled with a standard hydraulic-type grease nipple (Zerk fitting). This allows maintenance technicians to connect a manual grease gun directly to the external partition point to clear blockages or manually charge the circuit without breaking down the internal plumbing run.

  • Identical Metric Connections: The opposite side features a standard 24° internal cone tube seat machined to the same metric specifications as your main line, integrating directly with standard metric lubrication tubing loops globally.

Application & Compliance Standards

• Single Bite Sealing Integrity: Tightening the exterior compression nut drives the specialized cutting ring forward into the body seat, forcing it to bite cleanly into the exterior surface of the copper, steel, or high-pressure nylon tubing. Simultaneously, the heavy-duty locknut keeps the coupling locked stationary against the partition face. This rigid mechanical connection creates an unyielding seal that easily withstands high industrial vibrations, continuous machine cycling, and pressure shocks.

• Global Interchangeability: Manufactured in strict conformity with ISO 8434-1 and DIN 2353 extra-light guidelines. These straight bulkhead female couplings offer complete, drop-in compatibility with leading international fluid-handling brands. They serve as the trusted default choice for commercial vehicle chassis, wind turbine bearings, progressive distribution blocks, heavy mining machinery, and automated industrial assembly systems.
