This essential heavy-duty hardware kit features a robust compression lock spring, thick metal washers, a specialized T-bolt guide, and a heavy brass barrel nut. Its vital structural role is to thread directly onto the main clamp band T-bolt, where the spring continuously absorbs intense hydraulic pressure fluctuations from the pool pump, providing a high-tension counter-force that prevents the barrel nut from backing off or loosening over time. By maintaining absolute, uniform perimeter compression around the main tank O-ring, this assembly ensures a permanent watertight and airtight seal for the pressure vessel and acts as a primary fail-safe against catastrophic lid separation. Built to withstand continuous outdoor weathering, intense structural torque, and harsh chemical exposure without rusting or losing its tension capacity, the complete heavy-duty barrel nut and spring assembly carries an individual product and shipping weight of approximately \u003cb\u003e0.45 pounds\u003c\/b\u003e (about 7.2 ounces).\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c!----\u003e\n\u003c\/div\u003e","brand":"Commercial Pool and Spa Supplies","offers":[{"title":"Default Title","offer_id":53322567155823,"sku":"53108900Z","price":89.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0678\/3785\/3807\/files\/53108900Z.webp?v=1782141883","url":"https:\/\/commercialpoolandspasupplies.com\/products\/pentair-spring-barrel-nut-assembly","provider":"Commercial Pool and Spa Supplies ","version":"1.0","type":"link"}
