Parker is widely recognized as the leading brand in the hydraulic industry, known for its high-quality and reliable hydraulic fittings. These connectors are not only the most commonly used but also the most comprehensive imported hydraulic joints available on the market today.

The Parker joint was originally invented by German engineer Ermto (Emitto) of Parker Hannifin in the 1930s. To honor his contribution, the fitting became known as the "Parker Ferrule Fitting." In China, technical support, product sales, customer service, and selection are managed by the official US Parker Hydraulics flagship store, ensuring quality and reliability.

One of the key features of Parker joints is their unique assembly method, which requires only two wrenches. After nearly 80 years of continuous innovation, EO factory has maintained a leadership position in the development of card-type pipe joint technology. Today, Parker pipe joints are the most widely used globally due to their compact design and high-pressure capabilities.

Parker pipe joints are designed for metric pipes and historically followed German standards such as DIN 3861, DIN 3859, and DIN 2353. These have since been replaced by the international ISO 834 standard. They come in three pressure series—low, medium, and high (LL, L, S)—offering the most efficient and space-saving solutions for various applications.

The materials used in Parker fittings include copper, stainless steel, and carbon steel with galvanization, allowing them to adapt to different fluid and environmental conditions. The stainless steel nut threads are silver-plated and pre-lubricated for sizes 15L-42L and 12S-38S. Smaller sizes use wax-sealed threads, which prevent galling and reduce tightening torque by up to 40%.

Parker offers over 50 versions of fittings, along with various functional components like swivels, ball valves, check valves, globe valves, and pressure taps. These can be combined to enhance system performance and ensure a more reliable seal.

Using substandard hydraulic joints can lead to failures caused by excessive vibration or sudden pressure spikes, resulting in dangerous "jetting" that endangers both equipment and personnel. It's essential to use genuine Parker hydraulic joints and follow proper assembly procedures to guarantee safety and performance.

Understanding how to distinguish between authentic and counterfeit products can help users make better choices. However, the most important step is to find a trusted Parker hydraulic joint supplier, ensuring peace of mind during purchase.

Tianjin Fuleer Technology Development Co., Ltd. has been supplying original Parker hydraulic joints for 15 years, offering extensive wholesale and support experience that has earned high recognition from customers.
