Key features

Wide Temperature Range: Engineered for extreme conditions, operating reliably from -40 C to +100 C without cracking or leaking.

Superior Corrosion Resistance: Features a nickel-plated brass thread and reinforced PA66 body, resisting road salt and moisture for a longer service life.

Vibration-Proof Locking: Utilizes a stainless steel collet (grip-then-seal) mechanism that prevents tube blow-off even under severe road vibration.

Zero-Leakage Seal: Precision-molded NBR O-rings ensure a tight, leak-free connection, maintaining stable air pressure in the brake system.

Tool-Free Installation: The push-to-connect design allows for quick assembly and disassembly without flaring, heating, or special tools.

High-Pressure Endurance: Rated to withstand system pressures up to 12.5 bar (180 PSI), meeting the demands of heavy-duty truck air circuits.

Lightweight & Robust: Combines glass-filled nylon and metal inserts to reduce overall vehicle weight while maintaining structural integrity.

Standard Compliance: Manufactured to meet ISO 7628 and SAE J844 standards, ensuring perfect compatibility with standard PA11/PA12 nylon tubing.

Reusable Design: Unlike crimped fittings, these can be disconnected and reconnected multiple times without damaging the tubing or fitting.

Versatile Applications: Ideal for air brake systems, air suspension, and auxiliary air lines on trucks, trailers, and buses.

Product Q&A

Q:What material is used for the body and thread? Is it resistant to rust and high pressure?

The body is made from reinforced Polyamide 66 (PA66) with glass fiber for impact resistance, and the thread is nickel-plated brass. This combination ensures excellent corrosion resistance (against road salt and moisture) and can withstand high system pressures up to 12.5 bar (180 PSI).

Q:What is the working temperature range? Will it crack in winter cold or summer heat?

Yes, our fittings are engineered for extreme climates. They operate reliably within a wide range of -40 C to +100 C. . Whether in freezing winter or scorching summer, they maintain stable performance without cracking or leaking.

Q:How do I install this fitting? Do I need special tools like wrenches or glue?

Installation is completely tool-free. Simply cut the nylon tube squarely and push it straight in until you feel a "click". The built-in stainless steel collet locks the tube securely. To remove, just press the release collar and pull the tube out. No glue, threading, or heating is required.

Q:Which size of tubing does this fit? Is it compatible with standard air brake hoses?

We offer a full range of sizes to match ISO 7628 and SAE J844 standards. Common sizes include 6mm, 8mm, and 10mm outer diameter tubing. Please check our product listing for specific measurements to ensure compatibility with your air brake or suspension lines.

Q:What types of vehicles or systems are these fittings suitable for?

These fittings are specifically designed for heavy-duty commercial vehicles. They are ideal for air brake systems, trailer connections, and air suspension lines on trucks, tractors, semi-trailers, and buses.
