Compatibility and Buyer Check
Before ordering, confirm that your existing salt cell connection uses a 2-inch Hayward-style union nut and tailpiece. These parts should be matched by size, thread style, and fitment, not by image alone.
If you are comparing similar replacement connection parts, review the Pool Guy Supply T-Cell 2-inch union nut tailpiece or the 2-pack salt cell 2-inch union nut and tailpiece replacement before choosing this Hayward set.
If your union connection is leaking, the problem may be the seal instead of the 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 Tailpiece Set Does
The union nut and tailpiece help connect the salt cell to the plumbing line on compatible Hayward salt chlorine generator systems. A damaged union part can cause leaks, poor sealing, difficult cell removal, or trouble tightening the connection after cleaning.
Replacing the union nut and tailpiece can help restore a better plumbing connection when the salt cell, O-ring, and surrounding pipe are still in usable condition. It will not fix low chlorine output, control box errors, salt-level problems, or a failed salt cell.
Before You Order
Check these details before purchasing:
- Confirm that your system uses 2-inch union connection parts.
- Compare the thread style and tailpiece shape with your existing part.
- Inspect the O-ring, salt cell ports, and pipe fittings for wear or cracks.
- Check whether you need a union set, O-rings, or a full salt cell replacement.
- If you are replacing nearby plumbing parts, the Hayward GLX-CELL pipe may also be useful.
- If you are checking the full salt chlorination setup, compare your equipment with the Hayward W3AQR15 AquaRite salt chlorination system.
- Do not reuse cracked, flattened, or damaged seals when installing new union parts.
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, as this can damage the threads or 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 or cracked O-rings during service.
- Keep the threads clean and free from debris.
- Do not overtighten the union connection.
- Avoid using tools unless the manufacturer instructions allow it.
- Check for leaks after every salt cell cleaning or replacement.
