Which type of fitting is recommended for use on a steel hydraulic line?

When it comes to selecting the appropriate fitting for a steel hydraulic line, using steel fittings is highly recommended. Steel fittings offer several advantages that make them suitable for high-pressure environments commonly found in hydraulic systems. They are strong, durable, and resistant to the wear and tear that can result from the movement and impact inherent in hydraulic applications.

Additionally, steel fittings can effectively handle high temperatures and pressures without deforming or leaking. They also maintain compatibility in terms of thermal expansion and contraction with the steel hydraulic line they are connected to, which prevents joint failures that can occur due to differing expansion rates between materials.

On the other hand, materials like plastic, brass, and copper can exhibit limitations when used in high-pressure hydraulic systems. For example, plastic fittings may not withstand the pressures present in many hydraulic fluids and can become brittle over time. Brass fittings, while more robust than plastic, are typically not as strong as steel and may have reduced performance in extreme conditions. Copper can also be less ideal for high-pressure applications due to its malleability, which can lead to fatigue and potential failure under repetitive stress.

Thus, using steel fittings on a steel hydraulic line ensures strength, durability, and reliability, making it the best choice for achieving a safe and effective hydraulic system
