Aurorasters R12T Marine Fuel/Water Separator 10-Micron Filter — 30 GPH, Transparent Bowl

The Aurorasters R12T is a 10-micron marine fuel/water separator that delivers 30 GPH flow while trapping water and particles to protect engines and fuel systems.

If you operate boats, generators, trucks or heavy machinery, clean fuel is essential to reliable performance. The R12T combines a high-capacity 3-layer synthetic filter element with a transparent nylon collection bowl and corrosion-resistant housing. It’s a direct-fit replacement for many Racor/Parker and common OEM part numbers, engineered for easier servicing and long service life.

How does the R12T remove water and particles from fuel?

The R12T uses a multi-stage separation process: heavy droplets and particulate are captured by the 10-micron element while the clear collection bowl lets you see water accumulation. An automatic exhaust feature helps evacuate contaminants so only clean fuel reaches the engine.

• 10-micron rated filter media captures 99% of particles at that size
• Three-layer imported synthetic fiber paper for efficient filtration
• Transparent nylon bowl shows water and debris for visual inspection
• Automatic exhaust device facilitates drainage of separated water and dirt

Will the R12T fit my vessel or equipment and how easy is it to install?

The R12T is designed as a plug-and-play, direct-fit replacement for a broad range of marine and industrial applications. It matches common port/thread sizes and listed replacement part numbers, so installation is typically straightforward for technicians and DIYers alike.

• Standard port/connecting size NPT ZG1/4-19 with M18 x 1.5 center thread
• Compatible replacements for Racor/Parker S3240, R12T, S3213, S3227 and similar
• Pre-fill procedure recommended: always prime the dirty side without opening the fuel cap
• Rotating filter design simplifies element changeouts and servicing

What materials and construction features improve durability and performance?

Durability comes from corrosion-resistant housing, premium filter media and a reusable transparent bowl that resists chemicals and cracking. The multi-layer synthetic filter paper protects fuel system components such as pumps, nozzles and cylinders from abrasive wear.

• Electrostatic powder-coated housing for long-term corrosion protection
• Imported synthetic fiber filter paper in three layers for consistent flow and capture
• Reusable clear nylon bowl allows inspection without disassembly
• Designed to maintain 30 GPH flow while trapping contaminants

How should I maintain the R12T to prevent engine problems?

Routine inspection and timely replacement of the filter element are key. Never reuse an old element; replace it at recommended intervals or when visible water and debris accumulate in the bowl. After replacement, prime the system and check for leaks before prolonged operation.

• Replace the filter element rather than attempting to clean and reuse it
• Prime and start the engine after installation, then inspect for leaks
• Drain the bowl when water is visible via the clear housing
• Follow equipment manufacturer recommendations for replacement intervals

Who is this for? The Aurorasters R12T is aimed at boat owners, marine technicians, fleet managers and equipment operators who require dependable fuel conditioning. It suits gasoline and diesel engines in marine, industrial, construction and generator applications where keeping fuel clean and water-free reduces downtime and protects fuel-system components. If you need a 10-micron, high-flow replacement that’s easy to service and engineered for corrosion resistance, the R12T is built for those needs.
