NISSAN 46272-2S400 Brake and Clutch Tube Retaining Clip

The genuine NISSAN 46272-2S400 (Brake Pipe Retaining Clip / SPACER-CLUTCH T) is a premium-quality, original factory fastener designed for the secure and stable positioning of hydraulic lines (brake and clutch pipes). This specialized spacer clip ensures that high-pressure lines do not contact metal body panels or other moving components, thereby preventing chafing, rubbing, and premature wear.

Technical Specifications and Features:

• Manufacturer: NISSAN (Genuine OEM part)
• Part Number: 46272-2S400
• Part Type: Brake pipe and clutch tube retaining clip / spacer
• Material Composition: Highly heat- and chemical-resistant, aging-resistant plastic (polyamide) engineered to withstand elevated engine bay temperatures, road salt, and moisture.
• Installation Location: Engine compartment, chassis, along the routing path of the clutch or brake system hydraulic lines.

Function and Importance:

The metal and rubber lines running through hydraulic systems (such as brake and clutch systems) are subjected to continuous vibration during vehicle operation. The NISSAN spacer clip plays a critical role in damping these vibrations. It maintains proper spacing between lines, preventing metal-on-metal friction that over time can lead to line chafing, microscopic cracks, and ultimately hydraulic fluid leaks (loss of pressure).

Signs of Wear and Need for Replacement:

Over the years, plastic fasteners can dry out, become brittle, and crack due to temperature fluctuations, environmental exposure, and UV radiation. The most common signs of failure include:

• Visually apparent cracks or breaks on the clip body.
• Noticeable play or rattling of the hydraulic lines during driving.
• Physical damage incurred during maintenance work (e.g., brake line replacement), when the aged, brittle clip snaps upon removal.

To ensure safe driving, damaged or loose retaining clips should be replaced promptly with genuine OEM parts to prevent hydraulic line damage and failures in the brake or clutch system.
