EO sleeve fittings are popular for their ease of assembly (requiring only two wrenches). After nearly 80 years of development, EO Plant has always maintained a leading position in the technology of sleeve pipe fittings. Today, EO fittings are the most widely used fittings in the world. EO fittings are designed for metric pipes, historically in accordance with the German standards DIN3861, DIN3859 and DIN2353, which have now been replaced by the international standard ISO8434. EO fittings are known for their small size and high pressure rating. Divided into low pressure, medium pressure and high pressure three series (LL, L, S series) so that a variety of different applications can achieve the most economical and space minimization of the solution.
EO2 joint material and specification
In addition to the most common galvanized carbon steel, the materials of EO pipe fittings are also available in copper and stainless steel to adapt to different fluid or environmental conditions. The screw threads of EO stainless steel joints are silver-plated and pre-lubricated (15L-42L, 12S-38S), and the smaller screw threads are waxed, which not only effectively eliminates the bite of the stainless steel threads, but also reduces the assembly tightening torque by 40%. EO fittings have more than 50 different forms, which can be flexibly selected for a variety of different applications, plus many EO functional fittings, such as rotary fittings, ball valves, check valves, globe valves, pressure measuring fittings, etc., can be used with EO fittings, which can greatly facilitate the matching of the system and improve the reliability of the system seal.
EO2 connector classification
EO fittings are divided into two basic series: EO progressive tube fittings and EO-2 tube fittings.
The EO-2 pipe joint is a patented product introduced to the market by the Parker Ermeto plant in recent years. It inherits the advantages of the traditional sleeve joint using the sleeve connection and the assembly is particularly convenient, and has the characteristics of more reliable sealing and more resistant to harsh conditions than the traditional sleeve joint. Another important breakthrough of the EO-2 pipe joint is its significant improvement in simplifying assembly operations, ensuring assembly quality and reducing maintenance costs, thus becoming a popular new generation of products. Many of the world's famous hydraulic equipment manufacturers and their end users use it as a designated companion product to ensure the sealing reliability of hydraulic piping systems. The successful application experience of EO-2 pipe joint has made it win high praise in the market. The advantages of EO-2 type pipe joint: ☆ The elastic seal replaces the hard seal method used by the traditional sleeve joint, and the sealing effect is more ideal. ☆ The assembly positioning ring ensures that the assembly is in place without excessive, and provides a simple and reliable inspection and identification mark. ☆ It does not damage the inner cone of the joint, and can replace the elastic sealing ring, greatly reducing the labor and material costs of maintenance. The standardized design still complies with ISO8434 / DIN2353 standard and is fully interchangeable with traditional sleeve joints.
