Injection-molded from a dense, chemically inert, and high-impact polymer composite, this small compression or threaded adapter fitting functions as the vital mechanical link inside the peak dome of the fiberglass tank shell. Its primary operational role is to cleanly connect the long internal 3\/8-inch or 1\/4-inch outer diameter air relief vent tubing directly to the underside of the main tank lid or upper bulkhead assembly.\u003c\/p\u003e\n\u003cp data-path-to-node=\"1\"\u003eBy anchoring this small venting pathway securely in place, the connector ensures that pocketed air gases naturally rising to the top of the pressurized container are continuously siphoned out through the manual air relief valve network. This automated internal gas bleed completely eliminates systemic pressure-locks, prevents dangerous air-bound hammer shock waves, and allows the high-volume commercial filtration vessel to safely handle massive fluid distribution velocities while sustaining continuous operating parameters up to 50 PSI without weeping, leaking, or experiencing internal tube detachment under intense pump vibration surges. Designed for an extensive lifespan permanently submerged in a highly dynamic, chemical-rich environment, its robust plastic framework resists structural warping, cracking, and corrosive breakdown from concentrated pool sanitizers like chlorine, bromine, and winterizing acid flushes. Due to its ultra-compact, lightweight plastic geometry, this individual internal air relief tube connector carries a nominal product and shipping weight of approximately \u003cb data-path-to-node=\"1\" data-index-in-node=\"1098\"\u003e0.10 to 0.25 pounds\u003c\/b\u003e (about 1.6 to 4.0 ounces).\u003c\/p\u003e","brand":"Commercial Pool and Spa Supplies","offers":[{"title":"Default Title","offer_id":53416203190383,"sku":null,"price":10.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0678\/3785\/3807\/files\/PAC-051-1402_medium_2ef8924c-0b91-457e-bd11-217001409d37.jpg?v=1782744786","url":"https:\/\/commercialpoolandspasupplies.com\/products\/pentair-black-triton-ii-tr140-air-relief-tube-1","provider":"Commercial Pool and Spa Supplies ","version":"1.0","type":"link"}
