When the union collars are<br \/>\ntightened, the R0737700 seals are compressed between the mating surfaces and create a reliable, flexible barrier that keeps the hydraulic circuit closed<br \/>\naround the cell, even under filtration pressure.<\/p>\n<ul>\n<li>Provide the primary seal between the cell body and the inlet and outlet unions.<\/li>\n<li>Compensate for small misalignments and thermal expansion in the pipework.<\/li>\n<li>Help maintain a clean, dry technical area by preventing slow drips and salt deposits.<\/li>\n<li>Recommended whenever the cell is refurbished or the union fittings are serviced.<\/li>\n<\/ul>\n<h3>Compatibility and typical use<\/h3>\n<p>The Zodiac R0737700 O-rings are used on salt chlorinators that share the same clear cell housing and union design.

If the union fitting seal is identified as R0737700, this pack contains the correct replacement O-rings.<\/p>\n<h3>When to replace the union O-rings<\/h3>\n<p>Union O-rings are exposed to pressure, temperature variations and pool chemicals and will gradually lose elasticity. Replacing them is a simple way to<br \/>\nsolve leaks and extend the life of the plastic fittings around the cell.<\/p>\n<ul>\n<li>Visible cracks, cuts or flattened areas on the existing seals.<\/li>\n<li>Persistent drips or salt crusts forming around the cell unions.<\/li>\n<li>O-rings that feel hard or brittle instead of soft and elastic.<\/li>\n<li>Any time the unions are dismantled for cleaning, winterising or cell replacement.<\/li>\n<\/ul>\n<h3>Installation guidelines<\/h3>\n<p>Replacing the Zodiac union fitting O-rings R0737700 is straightforward and can be done during routine maintenance. Always depressurise the filtration<br \/>\ncircuit before opening the unions.<\/p>\n<ul>\n<li>Stop the filtration pump, close the relevant valves and release pressure from the line.<\/li>\n<li>Unscrew the union collars and carefully separate the cell body from the pipe fittings.<\/li>\n<li>Remove the old O-rings from their seats and clean the sealing surfaces of the unions and cell body.<\/li>\n<li>Place the new R0737700 O-rings in the same grooves, making sure they are not twisted or pinched.<\/li>\n<li>Reassemble the unions by hand, tightening the collars evenly until the joint feels firm.<\/li>\n<li>Restart the pump and inspect the union area closely for any signs of leakage.<\/li>\n<\/ul>\n<h3>Care and good practice<\/h3>\n<p>Correct handling of the unions and seals helps the new O-rings to deliver a long, reliable service life.<\/p>\n<ul>\n<li>Avoid overtightening union collars, which can deform the seals and fittings.<\/li>\n<li>Do not use sharp tools near the O-ring seats when separating the unions.<\/li>\n<li>Inspect union seals at the start of each season and after any cell acid cleaning.<\/li>\n<li>Rinse the cell and unions with fresh water if exposed to concentrated chemicals.<\/li>\n<\/ul>\n<p>With new Zodiac R0737700 union O-rings installed, the cell connections remain properly sealed and the chlorinator can operate under its designed<br \/>\npressure conditions without unwanted drips at the inlet and outlet unions.<\/p>","protected":false},"excerpt":{"rendered":"<p>Zodiac O-ring for cell union fitting pack of 2 R0737700 The Zodiac O-ring for cell union fitting pack of 2 R0737700 contains the original seals used on the union connections of Zodiac salt chlorinator cells.
