An in-line valve in each branch lets you tune every nozzle independently, so the high side stops blasting sand around while the low side finally gets real flow. The valve body and stem are molded from the same saltwater resistant acetal copolymer as the rest of the Loc-Line system, with a nitrile stem seal, and the ball-and-socket ends snap straight into hose segments, nozzles, and connectors.\u003c\/p\u003e\n\n\u003ch3 style=\"margin:14px 0 4px;font-size:1.05em;font-weight:600;line-height:1.25;border-left:4px solid #006064;padding-left:8px;\"\u003eChoose Your Size\u003c\/h3\u003e\n\u003ctable style=\"border-collapse:collapse;width:100%;font-size:0.95em;\"\u003e\n\u003ctr style=\"background:#E0F7FA;\"\u003e\n\u003cth style=\"border:1px solid #B2EBF2;padding:6px 8px;text-align:left;\"\u003eValve\u003c\/th\u003e\n\u003cth style=\"border:1px solid #B2EBF2;padding:6px 8px;text-align:left;\"\u003eSKU\u003c\/th\u003e\n\u003cth style=\"border:1px solid #B2EBF2;padding:6px 8px;text-align:left;\"\u003eFits\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border:1px solid #B2EBF2;padding:6px 8px;font-weight:600;\"\u003e1\/2\" In-Line Valve\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #B2EBF2;padding:6px 8px;\"\u003eLOC69854\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #B2EBF2;padding:6px 8px;\"\u003e1\/2\" hose ID Loc-Line systems, the common size on nano and mid-size tank returns\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border:1px solid #B2EBF2;padding:6px 8px;font-weight:600;\"\u003e3\/4\" In-Line Valve\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #B2EBF2;padding:6px 8px;\"\u003eLOC69558\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #B2EBF2;padding:6px 8px;\"\u003e3\/4\" hose ID Loc-Line systems, the standard on larger reef returns and manifolds\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3 style=\"margin:14px 0 4px;font-size:1.05em;font-weight:600;line-height:1.25;border-left:4px solid #006064;padding-left:8px;\"\u003eHow to Use\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eSnap the valve in anywhere along the run: right at the bulkhead, mid-line, or just before the nozzle.
