The main function of Ermeto DIN male stud high pressure hydraulic tube fittings is to connect different numbers of tubes and hoses. This broad range of fittings is available in steel and in stainless steel.
EO-PSR - Ermeto Original Progressive Stop Ring fittings (acc. DIN 3861, DIN 2353) produce the high pressure, leak-free connections of tubes, components in hydraulic systems for reliable, trouble-free functioning of the entire units. With its basic function, the controlled progressive bite of EO-PSR into the tube, due to its unique internal geometry, is perfect for a broad range of applications, markets. Markets: • Automotive • Defence • Energy • Environment • Industrial • Infrastructure • Machine Tools • Material Handling • Mobile • Oil and Gas • Power Generation • Process • Transportation • Water
Features/benefits of the EO-PSR fitting range: • High pressure: EO-PSR can be used in applications of up to 800 bar (S series) and 500 bar (L series). Stretches the range of applications. • EO-LUB: Due to the special treatment of larger sized nuts (25S/28L and larger), the tightening torques of EO-PSR fittings have been reduced by 25%. Eases and speeds up assembly. Prevents under-assembly. • Over-tightening protection: The special geometry of the EO-PSR prevents the over-assembly of EO-PSR fittings. Helps to avoid cost and time-consuming repair. • Spring effect: Cost reduction because of the spring effect; re-tightening of the fitting is not necessary. • Safe assembly: Maximum safety of assembly - two distinctive cutting edges provide a progressive increase of the tightening torque of the EO-PSR. The noticeable end point of the assembly process contributes to maximum safety of assembly. • Multifunctional ring geometry - prevents over-tightening and additional costs for repair. • Procurement is easy and fast. EO-PSR is available worldwide. • Fast, easy and safe assembly - meets the requirements of the applicable standards for 24° cutting ring fittings.
Applications: • Mobile hydraulics – hydraulic drive units, working hydraulic systems • Power Generation – compressor stations in gas pipelines
