Raybestos Inline Magnetic Transmission & Power Steering Filter 3/8" Compact In-line, Captures Metal Particles

Raybestos Powertrain inline magnetic filter (3/8") captures metal particles to help keep automatic transmission and power steering fluid cleaner.

This compact inline filter installs in the 3/8" fluid line of automatic transmissions or power steering systems to remove ferrous debris and larger contaminants. It’s built to work with existing fluid lines and provides an economical way to protect valve bodies, pumps, and other precision components by catching metal shavings and sludge before they circulate through a system. The unit ships as the filter element only; hoses and clamps are not included, so plan to reuse or purchase fittings separately.

How does this inline magnetic filter help transmission and steering systems?

The filter uses magnetic attraction plus a mechanical element to trap metallic particles and larger contaminants that can accelerate wear. By reducing circulating debris, it helps maintain cleaner fluid and may support smoother component operation. It’s a preventative component, not a repair—regular service and proper fluid levels remain essential.

• Magnet captures ferrous particles from fluid flow.
• Filter media traps non-magnetic contaminants and sludge.
• Inline design mounts directly into 3/8" lines for compact installation.
• Helps protect pumps, valves, and close-tolerance parts from abrasion.

What size and fittings are required for installation?

This Raybestos filter is sized for 3/8" fluid lines commonly used on many transmissions and power steering hoses. The product includes only the filter body; you’ll need matching hose ends, clamps, or adapters to complete the install. Verify hose inner diameter and routing before ordering to ensure compatibility.

• Designed for 3/8" (inner diameter) fluid lines.
• Hose and hose clamps are not included with the filter.
• Use compatible fittings or adapters if factory connections differ.
• Allow enough hose length and proper routing to avoid kinks.

How often should the filter be serviced or replaced?

Service interval depends on vehicle use, fluid condition, and contamination levels; inspect the filter during routine fluid service or when diagnosing fluid-related issues. Replace the filter if you find heavy metal accumulation, damaged media, or reduced flow. Periodic checks can prevent progressive wear in transmission and steering components.

• Inspect during regular fluid and filter service intervals.
• Replace if magnet shows excessive debris or media is damaged.
• More frequent checks recommended for high-mileage or towing vehicles.
• Never ignore low-flow symptoms—investigate and replace as needed.

What performance benefits can owners expect after installation?

Owners can expect cleaner circulating fluid and reduced long-term exposure of moving parts to abrasive particles, which supports consistent component operation. This filter is an economical add-on that contributes to longer useful life of high-value transmission and steering parts when combined with proper maintenance.

• Improved fluid cleanliness and reduced particulate circulation.
• Potentially extended life of pumps, valves, and bearings.
• Cost-effective way to complement scheduled fluid changes.
• Simple installation without major system changes.

Who is this for: The Raybestos 3/8" inline magnetic transmission and power steering filter is aimed at mechanics, fleet operators, and vehicle owners who want an affordable, easy-to-install measure to reduce metallic contamination in fluid systems. It’s especially useful for vehicles with higher mileage, towing duty, or those undergoing routine transmission or steering service. Remember this listing includes the filter only—plan to supply compatible hoses and clamps for a complete installation.
