This kit pairs a full 25-foot length of 3\/16\" outside-diameter copper-nickel tubing with a comprehensive assortment of inverted tube nuts and union connectors so you can route and join lines without hunting down multiple parts. The copper-nickel alloy balances malleability and strength, letting you form bends by hand while resisting the corrosive effects of road salt and moisture that shorten the life of ordinary steel lines.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this tubing perform compared with steel or coated lines?\u003c\/h3\u003e\n\u003cp\u003eThe copper-nickel alloy resists rust and oxidation far better than plain steel or copper-coated iron, extending service life in climates with road salt or frequent moisture.
