Compressed Air Knee Coupling

Compressed Air Knee Coupling (90° Elbow)

Space-Saving, High-Performance Pneumatic Connections

Our Knee Couplings provide a reliable 90-degree bend for compressed air lines, making them essential for navigating tight spaces within milking robots, automated gates, and control cabinets. Designed for a secure "push-to-connect" fit, these couplings ensure a leak-free seal without the need for tools.

Key Features

• 90° Directional Change: Ideal for routing tubing around sharp corners or within compact enclosures, preventing airflow restriction and tube kinking.
• 360° Swivel Body: Most models feature a swivel base, allowing you to orient the tubing direction even after the fitting is tightened into a port.
• Instant Seal: The internal stainless steel gripping ring ensures the tube is held firmly, while the NBR O-ring provides a perfect airtight seal.
• High-Pressure Reliability: Engineered to handle standard industrial pneumatic pressures (typically up to 10 bar / 145 PSI).
• Corrosion Resistant: Built with nickel-plated brass threads and a high-impact polymer body to withstand the humidity of a dairy environment.

Technical Specifications

• Connection Types: Available in Tube-to-Tube (Union Elbow) or Thread-to-Tube (Male/Female Elbow).
• Compatibility: Optimized for Polyurethane (PU), Nylon (PA), and Polyethylene (PE) tubing.
• Common Sizes: Available in metric (4mm, 6mm, 8mm, 10mm, 12mm) and imperial sizes.

Applications in Dairy

• Milking Robots: Routing air lines for teat cup attachment and cleaning arms.
• Sort Gates: Connecting pneumatic cylinders in tight overhead rails.
• Wash-Down Areas: Managing air supply for drying or cleaning systems where space is at a premium.
