Operators are instructed to tighten the hardware until the coils of the spring compress entirely together, touching \"coil-to-coil\" (or leaving a tiny nominal gap depending on the specific manual instructions). This configuration provides the precise physical compression needed to contain massive hydraulic vessel pressure without stripping the metal threads or warping the fiberglass tank flange.\u003c\/p\u003e\n\u003ch3 data-path-to-node=\"5\"\u003eWeight and Shipping Profile\u003c\/h3\u003e\n\u003cp data-path-to-node=\"6\"\u003eBecause it is a short, incredibly dense, thick-gauge steel spring, it carries significant physical heft for its small footprint:\u003c\/p\u003e\n\u003cul data-path-to-node=\"7\"\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"7,0,0\"\u003e\u003cb data-path-to-node=\"7,0,0\" data-index-in-node=\"0\"\u003eActual Component Weight:\u003c\/b\u003e Approximately \u003cb data-path-to-node=\"7,0,0\" data-index-in-node=\"39\"\u003e0.45 to 0.60 pounds\u003c\/b\u003e (roughly 7.2 to 9.6 ounces) for the individual spring.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"7,1,0\"\u003e\u003cb data-path-to-node=\"7,1,0\" data-index-in-node=\"0\"\u003ePackaged Shipping Weight:\u003c\/b\u003e Typically scales at \u003cb data-path-to-node=\"7,1,0\" data-index-in-node=\"46\"\u003e1.0 to 1.5 pounds\u003c\/b\u003e when purchased as part of the complete replacement kit (which bundles the heavy compression spring, thick stainless washers, and a brass\/steel barrel nut) enclosed in a standard padded parts box or heavy bubble mailer.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Commercial Pool and Spa Supplies","offers":[{"title":"Default Title","offer_id":53762625110127,"sku":"178616Z","price":11.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0678\/3785\/3807\/files\/51rtbgHbdKL.jpg?v=1783608889","url":"https:\/\/commercialpoolandspasupplies.com\/products\/pentair-compression-spring","provider":"Commercial Pool and Spa Supplies ","version":"1.0","type":"link"}
