Standard central vacuum pipe slips into the coupling, letting you route exhaust air where you want it, and the fitting works in either direction.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWide side:\u003c\/strong\u003e 2\" inner diameter, 2-1\/4\" outer diameter\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNarrow side:\u003c\/strong\u003e 1-7\/8\" inner diameter, 2-1\/8\" outer diameter\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOrientation:\u003c\/strong\u003e reversible — usable in either direction\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eThe PVC pipe used in central vacuum systems has a thinner wall than SCH 40, but SCH 40 works here too: 1.5\" ID SCH 40 carries a 2\" OD, so it seats in the coupling just like vacuum pipe. Because SCH 40 wall is roughly three times thicker, the exhaust path narrows slightly — in practice this causes no adverse effects. A practical, low-cost fitting for finishing the exhaust side of your central vac installation.\u003c\/p\u003e","brand":"MD Central Vacuum","offers":[{"title":"Default Title","offer_id":50026653614330,"sku":"507EX","price":6.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0684\/3934\/3354\/files\/a588db5607d213da5add12ee2166a640.jpg?v=1786162421","url":"https:\/\/evacuumsandmore.com\/products\/motor-exhaust-coupling-for-central-vacuum-units","provider":"Vacuums and More","version":"1.0","type":"link"}
