<div class="productDescriptionWrapper"> Reducer 2&quot; to 1 1/2&quot;white sch 40 pvc fitting - recommended for all solar swimming pool heating systems because abs pipe/fittings do not have the uv inhibitors that pvc pipe/fittings have so it does not hold up in the sun nearly as well. After a couple of years of exposure abs may become brittle and crack. <div class="emptyClear"></div> </div>
