iFJF part No.: FJ-R12T-YB. R12T Nylon Water Collection Bowl for 120AT / S3240 Fuel Water Separator Product Overview The iFJF R12T clear nylon water collection bowl is a direct replacement for the drain bowl on Racor 120AT and S3240 series fuel water separators. Made from chemical-resistant transparent nylon, this bowl allows you to visually monitor water accumulation in your fuel system. The integrated drain valve at the bottom makes it easy to purge collected water without removing the bowl. Over time, original bowls can become cloudy, cracked, or develop leaks at the thread connection. This replacement restores full visibility and leak-free operation to your existing filter head. Compatible with all R12T, 120AT, and S3240 filter assemblies using the standard bowl thread pattern. Key Features Clear Nylon Construction: Chemical-resistant transparent material provides excellent visibility and durability won't cloud from diesel or biodiesel exposure. Visual Water Detection: Transparent design lets you see water accumulation instantly without disassembly critical for marine applications. Integrated Drain Valve: Easy-turn drain petcock at the bottom for quick water purging with no tools required. Direct OEM Replacement: Same thread pattern as Racor 120AT and S3240 filter bowls screws right onto your existing filter head. Universal Fit: Works with any filter head using the standard 120AT bowl thread pattern.

A: Yes, if your Racor unit is a 120AT or S3240 series. The thread pattern is a direct match simply unscrew the old bowl and install this one. Q: How do I prevent leaks at the threads? A: Use fuel-rated (yellow) PTFE thread tape or a diesel-resistant thread sealant on the bowl threads. Standard white plumber's tape breaks down in diesel and can cause slow seepage. Q: Can I use this on a tractor or Kubota? A: Yes. Many owners use this bowl as part of a Kubota BX and similar tractor fuel-filter upgrade to replace a factory plastic filter that freezes or plugs. It fits any head using the standard 120AT bowl thread pattern. Q: How often should I drain the bowl? A: Check before every trip or weekly during heavy use. Drain whenever you see a visible water layer at the bottom. In humid marine environments, check more frequently. Q: Is this bowl compatible with biodiesel? A: Yes. The chemical-resistant nylon is compatible with standard diesel, biodiesel blends up to B20, and gasoline. Q: Does it come with an O-ring seal? A: The bowl threads directly onto the filter head. We recommend reusing your existing O-ring if it's in good condition, or purchasing a new seal kit if the old one shows wear.
