SAE J524 covers cold drawn and annealed seamless low-carbon steel pressure tubing intended used for hydraulic lines and other applications. The J524 Seamless Hydraulic Tubing is especially favorable for flaring and bending, some industrial uses include aircraft, automotive, locomotive, vehicle, heavy equipment, and agricultural applications. Wiho metals supply and stock a large inventory of SAE J524 seamless tubing for the hydraulic applications and where fittings, couplings, and fluid lines are used. In addition, all of the tubes have an exceptionally bright and clean OD and ID.
