Stainless steel fittings with progressive rind DPR produce high pressure, leak-free tube connections and components in hydraulic systems. The main feature is the controlled progressive bite into the tube, due to a unique geometry.
EO-DUR Progressive Ring DPR for stainless steel fittings is a key element to 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-DPR 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-DPR fitting range: • Field assembly: EO progressive ring fittings can be assembled anywhere with just a couple of wrenches. For stainless steel tube simple presetting tools are available. No additional equipment or machine is required, so that costs can be minimized. • Silver plated threads: All threads of the EO-DUR stainless steel nuts are surface treated to reduce the tightening torques by 40% compared to non thread products. This feature simplifies the assembly process and reduces the assembly time. • Available sizes: Most EO fittings are available in 25 sizes from 4 to 42 mm tube OD. Additional reducers allow optimum dimensioning of each individual fluid line. This saves space and material costs. • 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%. This feature Eases and speeds up assembly. Prevents under-assembly. • Over-tightening protection: The special geometry of the EO-DPR prevents the over-assembly of EO-DPR 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-DPR. 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-DPR 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
