Zodiac 63 mm / 2 inch union adapter set R0748700
The Zodiac 63 mm / 2 inch union adapter set R0748700 is the original connection kit for installing Zodiac salt chlorinator cells on 63 mm or 2 inch
pipework. This set provides the correct unions and adapters to connect the clear cell body to larger diameter filtration lines while maintaining a
reliable, watertight seal.
Main features of the union adapter set
- Original Zodiac union adapter kit for 63 mm and 2 inch installations.
- Designed to connect the salt cell body safely to larger pool pipes.
- Includes matching unions and adapters for a complete connection set.
- Suitable for salt water and standard pool chemical environments.
Function and application
The adapter set R0748700 is used when the Zodiac salt chlorinator cell must be installed on 63 mm or 2 inch return lines instead of standard 50 mm
pipework. The kit adapts the clear cell body connections to the larger diameter and provides sealed unions so the cell can be removed easily for
inspection and cleaning.
- Adapts the cell connections to 63 mm metric and 2 inch imperial pipe sizes.
- Provides union style fittings so the cell can be dismantled without cutting the pipe.
- Helps maintain correct flow and minimal pressure loss around the cell.
Compatibility and typical use
The Zodiac 63 mm / 2 inch union adapter set R0748700 is designed for use with compatible Zodiac clear cell bodies. It is listed in spare parts
documentation as a connection kit for salt chlorinators installed on larger diameter pipework.
- Used on selected Zodiac Tri, Tri Expert and Hydroxinator cells.
- Suitable for installations with 63 mm PVC or 2 inch rigid pipe on the return line.
- Recommended when upgrading pipework or when the original adapters are worn or missing.
When to use or replace the adapter set
The adapter set is essential when the cell is installed in 63 mm or 2 inch plumbing and the original fittings are damaged or leaking. Replacing the
unions and adapters is often the most efficient solution to restore a clean, reliable connection.
- Cracks or deformation in the existing unions or adapter sockets.
- Persistent leaks around the cell connections despite new O-rings and correct tightening.
- Change of pipe diameter during a filtration upgrade that requires new connection pieces.
Installation guidelines
Installing the Zodiac 63 mm / 2 inch union adapter set R0748700 is a plumbing operation that should always be done with the filtration pump stopped
and the circuit depressurised.
- Stop the pump, close isolation valves and release pressure from the line.
- Cut or prepare the 63 mm or 2 inch pipe according to standard PVC installation practice.
- Glue the adapter sockets on the pipe ends with a suitable PVC solvent cement.
- Allow the adhesive to cure and then position the clear cell body between the unions.
- Fit the union nuts and seals, tightening them by hand until the joint is firm.
- Restart the system and check the cell connections carefully for leaks during the first operating minutes.
Care and good practice
Correct installation and periodic inspection help the union adapter set R0748700 to provide many seasons of leak free service.
- Avoid overtightening the union collars to prevent stress on the plastic parts.
- Support the pipework so the cell and unions do not carry excessive weight.
- Inspect the unions and seals at the start of each season and after winterising.
- Rinse fittings with fresh water if exposed to concentrated chemicals or cleaning products.
With a properly installed Zodiac 63 mm / 2 inch union adapter set R0748700, the salt chlorinator cell is securely connected to larger diameter pool
pipework and remains easy to access for regular maintenance.
