The Flextral HH-56 (HH-56) is a high-performance hose designed for the efficient handling of petroleum and water-based hydraulic fluids in various applications, particularly in suction lines or low-pressure return lines. The HH-56 belongs to the HH series and features an internal diameter of 3.5 inches, with an external diameter of 4.26 inches (108.00 mm), making it robust yet flexible enough to handle a minimum bend radius of 11 inches (280.00 mm). This hose is built to withstand challenging conditions with a maximum working pressure of 200 psi and a burst pressure minimum of 800 psi. Constructed from seamless, black, oil and heat-resistant synthetic rubber, the HH-56 ensures durability and reliability under varied temperatures ranging from -22°F to 275°F (-30°C to 135°C). The hose is reinforced with two textile braids along with a spiral wire that prevents collapsing under vacuum pressures up to 28 Hg, enhancing its structural integrity for rigorous use. The outer cover is also crafted from black synthetic rubber that is resistant to oil and heat, and it's MSHA approved for safety standards. With a weight specification of 2.88 lbs/ft and available lengths ranging from a minimum of 12 inches up to a maximum of 1200 inches, this hose offers flexibility in usage across different setups without compromising performance. It is typically paired with HAHB series couplings, ensuring secure and leak-proof connections essential for maintaining system efficiency and safety in hydraulic operations.
