Stainless Steel Central Lubrication Fittings: The Complete Solution for Reliable and Durable Systems

Ensure leak-free performance and maximum longevity for your automatic lubrication systems with our premium Stainless Steel Central Lubrication Fittings. Engineered for the most demanding industrial, mobile, and marine applications, these fittings provide precise and reliable connections for delivering grease and oil. Our comprehensive range includes Reusable Hose Fittings for flexible, serviceable assemblies and Compression Tube Fittings compliant with the ISO 8434-1 (DIN 2353) standard for rigid tubing. Made from corrosion-resistant AISI 316/316L stainless steel, they are the ideal choice for environments exposed to moisture, chemicals, and extreme pressures, ensuring your lubrication system operates flawlessly for years.

Product Range & Key Features

1. Reusable Hose Fittings
This system is designed for creating high-pressure hose assemblies in the field without the need for permanent crimping tools. It consists of a Hose Stud and a Threaded Sleeve, allowing for easy assembly, disassembly, and maintenance. Perfect for connecting to pumps, injectors, and manifolds in automatic lubrication systems.

2. Tube Fittings (ISO 8434-1 / DIN 2353 Compression Type)
These are the industry-standard fittings for creating secure, vibration-resistant connections on rigid plastic (e.g., PA) or metal tubing. The three-piece design—comprising a nut, a cutting ring (ferrule), and a body with a 24° cone—bites into the tube as it is tightened, forming a reliable, leak-proof seal that can be serviced if needed.

The table below outlines the key differences and specifications between these two core product lines:

Key Dimensions & Technical Specifications

Our fittings cover the essential size ranges for centralized lubrication systems:

  • Tubing Compatibility: For standard plastic tubing (e.g., PA 11, PA 12) and metal tubes in common metric outer diameters (OD).

  • Hose Compatibility: Designed for high-pressure hoses with 8.6 mm and 11.3 mm outer diameters.

  • Pressure Series (Tube Fittings): Available in LL (Very Light), L (Light), and S (Heavy) series to match specific system pressure requirements.

  • Configurations: Offered in straight connectors, 90° elbows, and 45° elbows to facilitate complex routing in tight spaces.

  • Thread Options: Various metric and other international thread types are available on the port side of the fittings for system integration.

Why Choose Our Stainless Steel Lubrication Fittings?

  • Superior Corrosion Resistance: Manufactured from AISI 316/316L stainless steel, our fittings withstand harsh conditions, including exposure to water, chemicals, and saline environments, far outperforming carbon steel.

  • Guaranteed System Integrity: Precision engineering and adherence to ISO 8434-1 ensure leak-free connections, which are critical for the consistent and reliable operation of the entire centralized lubrication system.

  • Ease of Installation & Maintenance: The compression design allows for easy assembly and disassembly. The reusable hose system eliminates the need for specialized crimping equipment, simplifying on-site repairs and system modifications.

  • Long Service Life & Reduced Downtime: The combination of durable materials, robust design, and serviceable connections minimizes failures and maintenance needs, reducing total cost of ownership.
