Quick Product Summary

The Jandy R0449000 is a genuine replacement tailpiece / union kit used on several Jandy pool-equipment families. Jandy PlusHP and VS PlusHP pump parts lists identify R0449000 as a set of two 2-inch x 2-1/2-inch tailpieces supplied with O-rings and coupling nuts. Jandy also lists R0449000 as a set of two polymer tailpieces with union nuts on Legacy LRZE/LRZM and LXi heater water systems. More recent Jandy TruChlor documentation identifies the same part number as a universal union assembly that includes two unions. Because R0449000 appears across multiple Jandy product families, verify the exact equipment model and parts diagram before purchase.

Best For

• Replacing damaged or cut PlusHP / VS PlusHP pump union tailpieces
• Servicing documented Jandy Legacy or LXi heater union connections
• Replacing the universal union assembly on supported TruChlor in-line feeders
• Matching equipment that specifically calls for Jandy R0449000

Why This Matters

• The union connection allows serviceable plumbing connections at supported Jandy equipment ports.
• A damaged tailpiece, coupling nut, or sealing O-ring can prevent the connection from sealing correctly.
• Using the documented Jandy kit helps preserve the intended connection geometry and serviceability.
• The set-of-two configuration supports inlet and outlet connection replacement where the equipment uses both unions.

Common Signs You Need This / Use This When

• An existing union tailpiece or coupling nut is cracked, damaged, or has been cut during replumbing.
• The equipment parts diagram identifies R0449000.
• You are servicing a supported PlusHP / VS PlusHP pump and need the complete tailpiece, O-ring, and coupling-nut set.
• You are repairing a documented Legacy, LXi, or TruChlor union connection that specifies R0449000.

Product Specifications

Compatibility / Fitment Notes

Jandy PlusHP and VS PlusHP parts lists specify R0449000 as the tailpiece set with O-rings and coupling nuts. Jandy Legacy LRZE/LRZM and LXi heater manuals also list R0449000 as the set-of-two polymer tailpiece / union-nut assembly. Jandy TruChlor documentation uses R0449000 as the universal union assembly on supported in-line feeder models. Do not assume compatibility with every Jandy pump, heater, or feeder; other Jandy equipment can use different union kits, including similar-looking tailpieces with different part numbers. Verify R0449000 in the equipment parts diagram before ordering.

Installation / Use Notes

Shut the equipment down and isolate water flow before servicing the union connection. Follow the applicable Jandy equipment instructions for pressure relief, disassembly, plumbing preparation, and reassembly. Inspect the mating surfaces and O-rings before installation, and do not overtighten union nuts. If replumbing is required, use the pipe preparation, primer, cement, cure-time, and fitting method specified for the equipment and plumbing material.
