This kit<br \/>\nincludes the complete inlet and outlet unions so you can connect the pump quickly and securely to 1\u00bd inch or 2 inch PVC pipe, ensuring a watertight,<br \/>\nservice friendly installation in the technical room.<\/p>\n<h3>Main features of the Pentair Superflo union fitting kit 170451<\/h3>\n<ul>\n<li>Original Pentair union fitting kit for Superflo circulation pumps.<\/li>\n<li>Includes both inlet and outlet unions for a complete pump connection.<\/li>\n<li>Suitable for 1\u00bd inch and 2 inch PVC pipework via stepped or bushing connection.<\/li>\n<li>Supplied with union nuts and seals for a reliable, leak free joint.<\/li>\n<\/ul>\n<h3>Function and role in the installation<\/h3>\n<p>The union fitting kit 170451 is mounted directly on the suction and discharge ports of the Superflo pump. Each union provides a secure threaded<br \/>\nconnection to the pump body and a smooth socket side for gluing PVC pipe or fittings. Using original unions simplifies pump installation, makes<br \/>\nfuture maintenance easier and reduces the risk of leaks compared with fixed glued connections.<\/p>\n<ul>\n<li>Allows easy connection and disconnection of the pump without cutting pipes.<\/li>\n<li>Ensures correct alignment and sealing with the factory Superflo pump ports.<\/li>\n<li>Supports both 1\u00bd inch and 2 inch pipe systems commonly used in residential pools.<\/li>\n<\/ul>\n<h3>Compatibility and typical applications<\/h3>\n<p>The Pentair Superflo union fitting kit 1\u00bd&#8221; &#8211; 2&#8243; 170451 is designed specifically for Superflo pool pumps that use 1\u00bd\u20132 inch unions on suction and<br \/>\ndischarge. It follows the original thread and sealing profile, so the union nuts and tailpieces fit directly on the pump housing.<\/p>\n<ul>\n<li>Compatible with Pentair Superflo pumps that specify reference 170451 as union kit.<\/li>\n<li>Suitable for new installations and for replacing damaged or leaking original unions.<\/li>\n<li>Ideal when converting an existing pump to Superflo while keeping 1\u00bd\u20132 inch pipework.<\/li>\n<\/ul>\n<h3>When to use or replace the Superflo union kit<\/h3>\n<p>A good union fitting set is essential for leak free operation and for quick pump servicing. Over time, unions can suffer from mechanical stress,<br \/>\ncross threading or chemical ageing of the seals.<\/p>\n<ul>\n<li>Cracked or deformed union nuts, especially around the gripping tabs.<\/li>\n<li>Persistent drips or salt deposits at the pump connections despite new seals.<\/li>\n<li>Damaged or seized threads caused by overtightening or incorrect tools.<\/li>\n<li>Upgrades or reconfiguration of the technical room where new unions are preferred.<\/li>\n<\/ul>\n<h3>Installation guidelines<\/h3>\n<p>Installing the Pentair Superflo union fitting kit 170451 is straightforward and should be done with the system depressurised and the pump disconnected<br \/>\nfrom the power supply.<\/p>\n<ul>\n<li>Switch off and isolate the pump electrically and close valves on the suction and return lines.<\/li>\n<li>If replacing old unions, loosen the union nuts, remove the existing fittings and clean the pump port threads and sealing faces.<\/li>\n<li>Fit the new union tailpieces and seals supplied in the kit, making sure each gasket is correctly seated.<\/li>\n<li>Position the pipework or adapters for 1\u00bd inch or 2 inch PVC and glue according to the adhesive manufacturer instructions.<\/li>\n<li>Screw the union nuts onto the pump ports by hand and tighten until snug; avoid using tools that could damage the plastic.<\/li>\n<\/ul>\n<p>After the adhesive has cured, reopen the valves, prime the pump and check the unions carefully during the first minutes of operation to confirm that<br \/>\nthe connections are completely watertight.<\/p>\n<h3>Good practice for durable connections<\/h3>\n<p>Correct handling and regular inspection extend the life of the Pentair Superflo union fitting kit 1\u00bd&#8221; &#8211; 2&#8243; 170451 and help the installation remain<br \/>\nservice friendly.<\/p>\n<ul>\n<li>Support the pipework on both sides of the pump so the unions are not loaded by the weight of the pipes.<\/li>\n<li>Do not overtighten the union nuts; hand tightening is usually sufficient for a good seal.<\/li>\n<li>Inspect seals periodically and replace gaskets if you notice seepage or flattening.<\/li>\n<li>Protect the technical area from extreme temperature changes and direct sunlight when possible.<\/li>\n<\/ul>\n<p>With a correctly installed Pentair Superflo union fitting kit 1\u00bd&#8221; &#8211; 2&#8243; 170451, the pump is securely connected to the filtration circuit while<br \/>\nremaining easy to remove for maintenance, ensuring a clean, professional finish in the plant room.<\/p>","protected":false},"excerpt":{"rendered":"<p>Pentair Superflo union fitting kit 1\u00bd&#8221; &#8211; 2&#8243; 170451 The Pentair Superflo union fitting kit 1\u00bd&#8221; &#8211; 2&#8243; 170451 is the original suction and discharge connection set for Pentair Superflo pool pumps.
