Catalog 4300 EO Progressive Ring Fittings — Introduction The flareless bite type fitting was pioneered by Ermeto in Germany in the early 1930’s. When Parker Hannifin acquired Ermeto, it introduced the EO fittings to the US. Today, the EO fittings are the most widely used bite type fittings in the world. The EO progressive ring fitting is a flareless metric fitting (for metric tube)that consists of a body, a progressive ring (ferrule) and a nut. On assembly, two cutting edges of the progressive ring “bite” into the outer surface of the tube ensuring the necessary holding power and seal for...

Catalog 4300 EO and EO-2 Metric Bite Type Fittings   The stop edge causes a sharp increase in tightening forces which is clearly perceptible. After assembly, a visible collar of cut tube material must completely fill the space in front of the first cutting edge. With stainless steel tube and hose connections made from free cutting steel, the collar is less due to the harder material. Stop edge (collar) Second bite edge Front bite edge During assembly, it is absolutely essential that the tube is held firmly against the stop in the inner cone of the fitting; if not, the cutting process will...

Catalog 4300 Fitting Instructions: The life of a rotary fitting depends considerably in a stress-free line connection.Therefore, the direct connection with tube is to be avoided. For connection to hoses, the use of swivel nut fittings is recommended with short, straight lines (approx. length 5x hose O.D.). Thus, shocks and vibrations can be absorbed. EO and EO-2 Metric Bite Type Fittings   Features, Advantages & Benefits • Non-Return Valves • Characteristics: Sealing is achieved by using a 90° cone with a packing washer of synthetic material. Valve has a lift stop which provides safe free...

Catalog 4300 • • • • Finish — Steel EO fittings have a zinc clear Chromium-6 Free finish. This finish provides good corrosion protection. Silver Plated Nuts — Stainless steel tube nuts are prelubricated with silver plated threads (size 15L-42L, 12S38S). Thread galling is eliminated and assembly torque is reduced as much as 40 percent. This increases the speed and efficiency for stainless steel fitting assembly. Availability — EO fittings are available as standard in over thirty different configurations, and as many as twenty-seven different size combinations in some configurations....

EO and EO-2 Metric Bite Type Fittings Catalog 4300   How EO-2 Fittings Work The retaining ring bites into the tube in accordance to the proven bite ring principle. The elastomeric seal reduces the danger of over- or underassembly by a special EO-2 design feature: Before assembly there is a gap in between the flat surfaces of the retaining ring and the metallic support ring of the seal. As soon as the retaining ring has reached the proper incision depth, the gap closes, resulting in a sharp increase of assembly torque. This results in uniform and reliable fitting assemblies. The assembly...

EO and EO-2 Metric Bite Type Fittings Catalog 4300   Features, Advantages and Benefits of the EO-2 Fitting System • In addition to the general advantages of the EO tube fitting system, the unique EO-2 fitting features offer even more specific benefits: • Sealing Capability — An elastomeric seal forms the primary sealing element, thus assuring leak-free sealing. Even low-viscosity media such as water or gas are hermetically sealed. Hydraulic systems, therefore, do not “sweat” at fittings. • High Pressure Resistance — EO-2 fittings are rated up to Pmax 900 bar. Sealing lip and seal...
