It is the fitting you use when the pump or filter is 1.5 inch and the plumbing around it is 2 inch, which is a very common combination on a modern system.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy the O-ring matters\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe threaded side seals on an O-ring, not on thread tape. That removes the whole ritual of wrapping, testing, unwrapping and rewrapping, and more importantly it removes the reason people overtighten. A tapered thread pulled up hard into a plastic housing is how pump and filter ports get cracked, and it is an expensive way to fix a small leak.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHi-temp construction\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe body is CPVC and PVC rather than plain PVC, so it handles the warmer water on the discharge side of a heater without going soft. The union face itself seals on a T ring.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eServiceability\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe point of a union is that it comes apart. Loosen the nut and the equipment separates from the plumbing, so a pump can be pulled for a seal change or a filter opened without a saw and a bag of couplings.\u003c\/p\u003e","brand":"CMP","offers":[{"title":"Default Title","offer_id":48627842318548,"sku":"CMP-21063-160-000","price":17.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_43740c99-c54f-48c2-84d2-56b1711dbb7b.jpg?v=1788728141","url":"https:\/\/www.activepoolsupply.com\/products\/union-1-5-thread-x-2-slip-hi-temp","provider":"Active Pool Supply","version":"1.0","type":"link"}
