The feature of EO-2 fittings is elastomeric seals on all joints. It assures leak free operation without retightening. EO-2 is designed for metric tube, based on German standards DIN 3861, DIN 2353, now represented by international standard ISO 8434-1.
The feature of all EO-2 fittings is elastomeric seals on all joints. It assures leak free operation without retightening. EO-2 is designed for metric tube and based on German Standards DIN 3861, DIN 2353, today represented by international standard ISO 8434-1. The elastomeric seal assures a hermetically sealed tube joint. It is located between the inner cone of the fitting body and the tube surface, thus blocking the only possible leak path. The sealing effect is pressure supported which makes the EO-2 fitting suitable for high-pressure applications. The static compression also eliminates air-ingress into the fluid system at vacuum conditions. Features, advantages, benefits of the EO-PSR fitting range: High pressure: EO-2 can be used in applications of up to 800 bar (S series) and 500 bar (L series). EO-2 exceeds the DIN/ISO requirements and guarantees a 4-fold design factor. EO-LUB: Due to the special treatment of larger sized nuts (25S/28L and larger), the tightening torques of EO-2 fittings have been reduced by 25 %. This makes assembly easier and prevents underassembly. Sealing capability: An elastomeric seal forms the primary sealing element, thus assuring leakfree sealing. Even low-viscosity media such as water or gas are hermetically sealed. Hydraulic systems therefore do not "sweat" at fittings. Functional nut: Individual components (retaining ring, seal) cannot be lost, forgotten, confused or assembled in the wrong orientation. This saves assembly costs and avoids dangerous assembly errors. EO-2 functional nut can be used for the whole variety of the broad range of more than 50 configurations in some 25 sizes of standard EO LL, L and S series. Assembly costs: With less than 10 seconds cycle time on the EOMAT, the cost of presetting EO-2 is extremely low. Easy, visible inspection of assembly result. EO-2 fittings can be disassembled and reassembled many times. Applications: Machine tools, mobile hydraulics, shipbuilding/offshore, transportation
