The Red/Blue Carbon Steel TSBA08 Anti-Pollution Hydraulic Fittings are premium-grade connectors designed to maintain hydraulic system cleanliness and efficiency by minimizing contamination during installation and operation. Constructed from high-strength carbon steel with a durable electroplated finish, these fittings feature a unique anti-pollution design that prevents dirt, dust, and moisture from entering the hydraulic circuit. The color-coded red/blue coating (red for high-pressure lines, blue for low-pressure) simplifies system identification, while the TSBA08 thread standard ensures compatibility with international hydraulic components. Ideal for heavy-duty applications, these fittings deliver reliable performance under high pressure and harsh conditions, making them essential for construction machinery, agricultural equipment, and industrial hydraulics.
1. Anti-Pollution Design: The fitting’s male and female ends are equipped with protective caps and seals that remain in place until installation, preventing foreign particles from entering the system. The internal threads are machined to tight tolerances (ISO 6149-1) to reduce burrs and metal shavings.
2. High-Strength Carbon Steel Construction: Heat-treated carbon steel (grade C45) provides a tensile strength of 800 MPa, ensuring resistance to deformation and cracking under high-pressure loads (rated up to 400 bar). The zinc-nickel electroplated finish offers superior corrosion resistance (500+ hours salt spray test).
3. Color-Coded Pressure Identification: The red coating indicates suitability for high-pressure lines (200–400 bar), while blue is for low-pressure applications (0–200 bar), simplifying correct installation and reducing the risk of misconnection in complex hydraulic systems.
4. TSBA08 Thread Compatibility: Compliant with the TSBA08 (Triangle Seal British Association) thread standard, these fittings are compatible with most European and Japanese hydraulic components, including Parker, Eaton, and Yuken systems.
5. Leak-Free Sealing: The conical seat and O-ring groove (optional) provide dual sealing mechanisms, ensuring a tight fit even in high-vibration environments. For critical applications, use with hydraulic thread sealant for enhanced reliability.
• Construction Machinery: Used in excavators, loaders, and cranes to connect hydraulic cylinders, pumps, and valves, maintaining system cleanliness in dusty, muddy environments.
• Agricultural Equipment: Suitable for tractors, combines, and sprayers, where exposure to dirt, moisture, and crop debris demands robust anti-pollution protection.
• Industrial Hydraulics: Ideal for press machines, injection molding hydraulic systems, and steel mill equipment, ensuring consistent performance under heavy loads and extreme temperatures.
• Mobile Hydraulics: Perfect for truck-mounted cranes, forklifts, and aerial work platforms, where quick connections and contamination control are essential for safety and efficiency.
Q: What is the primary benefit of the anti-pollution design?
A: The protective caps and sealed threads prevent up to 99% of external contaminants from entering the hydraulic system during storage and installation, reducing the risk of pump damage and valve failures.
Q: Can the color coding be customized for specific applications?
A: Yes, custom color coatings (e.g., yellow for medium pressure) are available for bulk orders, along with laser-engraved pressure ratings for enhanced visibility.
Q: Are these fittings compatible with biodegradable hydraulic fluids?
A: Yes, the zinc-nickel plating is resistant to most eco-friendly fluids. However, regular inspection is recommended for fluids with high water content.
Q: What is the recommended torque for tightening these fittings?
A: Torque values depend on thread size—refer to the technical manual for specific guidelines (e.g., 50 N·m for M22x1.5 threads). Over-tightening may damage the sealing surface.
Q: Do you offer stainless steel versions for food-grade hydraulics?
A: Yes, 316 stainless steel fittings with FDA-compliant seals are available for applications requiring hygienic standards, such as food processing and pharmaceutical machinery.
