Jandy 2" x 2" Tailpiece O-Ring and Union Nut Kit
Product Overview
Pool techs reach for the Jandy R0327301 kit when a cracked union nut or flattened O-ring threatens the airtight seal of a pump or heater connection.
This genuine Jandy 2" x 2" Tailpiece O-Ring and Union Nut Kit (R0327301) provides the exact tolerances required for a leak-free connection on Jandy Stealth, PlusHP, and MaxHP pumps. Unlike generic fittings that may warp under high pressure or heat, this OEM kit ensures the suction side remains airtight to prevent pump priming issues and cavitation.
Benefits & What Makes It Different
OEM Precision Fit
The R0327301 kit is engineered specifically for Jandy equipment, ensuring the threads won't cross or strip during high-torque installations.
High-Temperature Durability
The composite material in this union nut reliably handles the heat cycles of JXi and LXi heaters without becoming brittle or cracking over time.
Airtight O-Ring Seal
The included O-ring provides a critical barrier against air leaks, which is essential for maintaining consistent water flow and pump prime.
Compatibility
- Jandy Stealth (SHPF/SHPM) Pumps
- Jandy PlusHP (PHPF/PHPM) and MaxHP (MHPM) Pumps
- Jandy JXi and LXi Pool Heaters
When To Use This
Pro Tip
Always apply a thin layer of silicone-based lubricant to the O-ring before installation; this prevents the rubber from pinching or tearing when you hand-tighten the nut.
Common Questions & Instructions
How do I know if I need to replace my Jandy union nut?
If you see hairline cracks in the plastic or water dripping from the connection even after tightening, the R0327301 kit is the standard specification for a permanent fix.
Can I use this kit on other pump brands?
While some 2-inch unions look similar, this specific R0327301 kit is designed for Jandy's proprietary threading and tailpiece dimensions to ensure a leak-proof seal.
How often should the O-ring be replaced?
In our experience, O-rings should be inspected annually and replaced every 2 to 3 years, or whenever they appear flattened or lose their elasticity to prevent air leaks.
