Racor RK 15211 Seal Service Kit – 500 Series Turbine Fuel Filter/Water Separator

Part Number: RK 15211 / RK15211 (distributor SKU: 62-RK15211)
Brand: Racor
Type: Seal service kit — O-rings and sealing components for 500 Series turbine fuel filter/water separator rebuild
Compatible series: Racor 500 Series turbine fuel filter/water separators (500FE, 500FF, 500FG, 500MA)
Weight: 567 g

Product Overview

The Racor RK 15211 is a seal service kit containing the O-rings and sealing components needed to rebuild the sealing surfaces of a Racor 500 Series turbine fuel filter/water separator during scheduled maintenance or after a seal failure. Rather than replacing the entire filter housing, the RK 15211 restores proper sealing performance by renewing the critical sealing components at a fraction of the cost. This kit is the correct service part when the 500 Series assembly is being disassembled for a thorough inspection and rebuild.

• Contains O-rings and sealing components for a complete 500 Series seal rebuild
• Restores proper sealing on Racor 500 Series turbine fuel filter/water separator assemblies
• Designed for scheduled maintenance or post-failure seal restoration
• Genuine Racor service kit
• Compatible with 500FE, 500FF, 500FG, and 500MA turbine series assemblies
• Weight: 567 g

Compatible Applications

• Racor 500FE turbine fuel filter/water separator — seal rebuild/service
• Racor 500FF turbine fuel filter/water separator — seal rebuild/service
• Racor 500FG turbine fuel filter/water separator — seal rebuild/service
• Racor 500MA turbine fuel filter/water separator — seal rebuild/service
• Any 500 Series turbine assembly requiring replacement of seals and O-rings during scheduled maintenance or after a leak or seal failure

Note: Confirm your specific 500 Series model designation before ordering. The RK 15211 is the seal service kit — it does not include the replacement filter element. The filter element is a separate service item and should be replaced on the engine/system manufacturer’s maintenance schedule.

Service Information

Replace the seals and O-rings in the Racor 500 Series assembly during scheduled overhaul intervals, or immediately if fuel leakage, weeping around sealing surfaces, or contamination ingress is detected. Follow the Racor 500 Series service manual for the correct disassembly sequence, seal replacement procedure, and reassembly torque specifications.

Installation Notes

• Shut off fuel supply and depressurize the fuel system before beginning disassembly
• Disassemble the 500 Series housing following the Racor service manual sequence — do not force components
• Remove all old O-rings and seals; inspect all sealing surfaces for scoring, contamination, or damage before reassembly
• Clean all sealing surfaces thoroughly and remove any debris or old sealant residue
• Lightly lubricate new O-rings with clean diesel or a compatible O-ring lubricant before installation — do not use petroleum-based greases incompatible with fuel systems
• Install new seals per the Racor service manual; do not over-compress O-rings during reassembly
• Reassemble and torque to specification; pressure-test before returning the system to service
• After returning to service, inspect all sealing surfaces for leaks during the first several hours of operation

Technical FAQ

Does this kit include the replacement filter element? No — the RK 15211 contains sealing components only. The filter element is a separate replacement item. Refer to the Racor 500 Series element cross-reference for the correct element part number for your application and micron rating.

What Racor 500 Series models is this kit for? The RK 15211 is designed for the 500 Series turbine fuel filter/water separator family, which includes the 500FE, 500FF, 500FG, and 500MA assemblies. Confirm your specific model designation before ordering.

When should the seals be replaced? Replace seals during a scheduled overhaul, whenever fuel weeping or leakage is present at sealing surfaces, or anytime the housing is fully disassembled for inspection. Seals should not be reused after disassembly.

Can I reuse the old O-rings if they look undamaged? No — O-rings and seals should always be replaced during a rebuild regardless of visual condition. Reused seals are a common cause of post-service leaks.

Parts Desk Insights

The RK 15211 is the seal rebuild kit for the Racor 500 Series — the right part when the housing is being disassembled and the seals need renewing. The most common mistake is customers ordering this when they only need a replacement filter element — clarify whether the customer is doing a full housing rebuild (needs this kit) or just a routine filter change (needs the element only). Also stress that O-rings must never be reused after disassembly — this is the single most common cause of post-service fuel leaks on these assemblies. Clean sealing surfaces and light O-ring lubrication before reassembly are critical steps that are often skipped in field service situations.
