Compatibility and Buyer Check
Before ordering, confirm that your system uses a 2-inch GLX-CELL style union connection. These parts should be matched by size, thread style, tailpiece shape, and fitment, not by image alone.
If you are comparing similar Hayward-style union parts, review the Hayward 2-inch union nut tailpiece salt generator replacement before ordering this 2-pack. You can also compare the Pool Guy Supply T-Cell 2-inch union nut tailpiece if you are checking another compatible replacement option.
If your salt cell connection is leaking, the issue may be the O-ring instead of the union nut or tailpiece. In that case, check the Hayward GLX-UNION T-cell union O-ring replacement before replacing the full union connection parts.
What This Union Nut and Tailpiece Set Does
The union nut and tailpiece help connect the salt cell to the pool plumbing line on compatible Hayward-style salt chlorine generator systems. A worn or damaged union connection can cause leaks, poor sealing, difficult cell removal, or trouble tightening the cell after cleaning.
Replacing the union nut and tailpiece can help restore a secure connection when the salt cell body, O-ring, and surrounding plumbing are still in good condition. This part will not fix low chlorine output, bad salt readings, control box errors, or a failed salt cell.
Before You Order
Check these details before purchasing:
- Confirm that your system uses a 2-inch salt cell union connection.
- Compare the thread style and tailpiece shape with your original part.
- Inspect the salt cell ports for cracks, worn threads, or damage.
- Check the O-rings before replacing the union parts.
- Confirm whether you need union parts only, O-rings, or a full cell replacement.
- If you are maintaining the plumbing area around the cell, the Hayward GLX-CELL pipe may also be useful.
- If the existing union is hard to loosen during salt cell service, review the Hayward Turbo Cell salt cell wrench before using force on the connection.
Installation Notes
Turn off the pool pump and salt chlorine generator before removing the old union parts. Relieve pressure from the plumbing line before loosening the connection.
Remove the old union nut and tailpiece carefully. Clean the sealing surface and inspect the O-ring before installing the replacement parts. Hand-tighten the union and avoid cross-threading or overtightening, because this can damage the threads or salt cell connection.
After installation, restart the pump and check the connection for leaks while water is flowing.
Maintenance Tips
To help prevent future union leaks:
- Inspect union nuts and tailpieces whenever the salt cell is removed.
- Replace worn, flattened, or cracked O-rings during service.
- Keep threads clean and free from debris.
- Do not overtighten the union connection.
- Avoid using tools unless needed and safe for the fitting.
- Check for leaks after every salt cell cleaning or replacement.
