Before adding to cart, locate the manufacture date on your pump's label — it is typically printed on the motor nameplate or the pump body. If your pump was manufactured in 2018 or after, order two (2) of this collar. If manufactured before 2019, one (1) is sufficient. When in doubt, ordering a pair ensures you have the correct quantity on hand without a second trip.\u003c\/p\u003e\n\n\u003c!-- wft:processed:manual:2026-05-01 --\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":52772589338899,"sku":"U11-200PSZ","price":13.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0920\/0687\/5411\/files\/pentair-union-collar-2-inch-u11-200psz-1.webp?v=1766182332","url":"https:\/\/poolaroo.com\/products\/pentair-union-collar-2-u11-200psz","provider":"Poolaroo","version":"1.0","type":"link"}
