In 1934, this idea was patented and today it is just asuseful as it was on the very first day. Considering the rangeof applications, quality, reliability and functional safety, theprinciple of the Parkers cutting ring fitting has been a lead-ing system up to today.Ofcourse,thishasonlybeenpossiblebycontinuouslyadapting the original invention from 1934 to the practicalrequirements of state of the art technology. Thus, the firstParker Ermeto cutting ring has little left in common with thelatestmultifunctionalPSRcuttingring,theheartofEO-Plus.TheEO-Plusfittingmeetstherequirementsofmodernhydraulic systems. This is especially true for applicationswhere the systems are exposed to extremely high loads.EO-Plus is designed for metric tube and based on GermanStandards DIN 3861 and DIN 2353, which today are repre-sented by the international standard ISO 8434-1. EO-Plusis available in L- and S-Series.ThePSR(ProgressiveStopRing)isavailableforthesteelfitting range. For stainless steel applications, the Progressivering DPR 71 is used and the Cutting ring for brass fittings andseries LL.EO-Plus fitting featuresTheEO-Plusfittingproduceshighpressure,leakfreeconnection of tubes and components in fluid systems.

This makes assembly eas-ierandpreventsunderassembly,themostcommonreason for tube fitting failure. Plus:Safeassembly Twodistinctivecuttingedgesprovide a progressive increase of the tightening torqueof the PSR. The noticeable end point of assembly con-tributes to maximum safety of assembly, and the multi-functional ring geometry prevents over-tightening. Plus: Overtightening protection The special geom-etry of the PSR prevents the overassembly of EO-Plusfittings. Plus: Spring effect Thanks to the spring effect, re-tightening of the fitting is not necessary. Upon the com-pletion of the assembly (due to the geometry, materialand heat treatment) an elastic initial tension is achievedwhich compensates displacement effects in the threadand at the bite point of the tube.

This product hasproven to be extremely effective in eliminating leaks at thehigher pressures found in todays hydraulic systems.TheO-LokPlusfittingisanO-ringfaceseal(O.R.F.S.)type fitting that consists of a nut, a body, an O-ring and asleeve. As shown in Fig. 1 the tube is flanged to 90 usingthepatentedParflangesystem(orthetubemaybebrazed instead to a braze-type sleeve). When the fitting isassembled, it compresses an O-Ring in the precision-ma-chined groove in the fitting body to form a leak-tight seal.O-Lok Plus fittings are suitable for a wide range of tubewallthicknessandarealsoreadilyadaptabletoinchormetric tubing and hose connections.Fig. 1 O-Lok Union cutaway with flanged and brazed assembliesBraze SleeveO-ringParflangeSleeveFitting BodyO-Lok PlusThelasttwentyyearsofexperiencesupplyingO-LokPlus have been well used in terms of listening to customerneeds and refining design and material details to achievethe optimum mix of headline performance and a long trou-ble-free service life.

Anywhere in factwhere a high quality leak-free tube or hose connection isneeded.Function of O-Lok Plus fittingsThe O-Lok Plus fitting consists of four main components:a body, a sleeve, an O-ring and a nut.The O-Lok Plus fitting bodyThere are over 40 different body configurations to choosefrom for specific applications. The body face has a groove,which contains a high durometer O-ring that is held cap-tive during installation. In addition, the O-Lok Plus fittingbody shapes are all forged for added strength and longerservice life.Straightfittingsaremadefromcolddrawnbarstock.

Larger size nuts are made ofwarm-forged steel-blanks.The O-Lok Plus Parflange sleeveThe preferred method of making an O-Lok Plus tube con-nection is by using the Parker Parflange process to cre-ate the 90 flange on the tube end. A flange sleeve is usedto support the flange and the tube, and provides the con-tact shoulder for the nut. After the Parflange process, thesleeve is permanently fixed on the end of the tube reinforc-ing the joint.The O-Lok Plus connection using the Parflange methodcan be made with either metric or inch tubing by choosingthe appropriate sleeves and tooling.ParflangesleevesfromParkeraremanufacturedtoex-actingtolerancesandgeometrytoworkwiththePar-Fig 1 Captive O-ring Groove (CORG) cutawayFunction of fittingsA22 Catalogue 4100-7/UKflangemachineandtooling,producingtherobust,rein-forcedtubeendconnection.Failuretousethecorrectcomponents can result in premature joint failure in the finalapplication.The O-Lok Plus braze sleeveThe braze sleeve provides the mating surface between thetubeandthefittingbody.Secondly,thebrazesleeve,asthenameimplies,isattachedtothetubethroughsilverbrazing.

The reducing sleeves make it easy toadapt a larger face seal fitting to a smaller tube connec-tion.O-Lok Plus fitting functionThe O-Lok Plus fitting body face contains a high durome-terO-ringthatisheldcaptiveinaprecisionmachinedgroove. As the nut is tightened onto the fitting body, the O-ring is compressed between the body and flat face of thetubeflangeorbrazesleevetoformatight,positiveseal(see Fig. 1).As the two faces come in contact, further tightening of thenut produces a sharp rise in assembly torque. A solid pullof the wrench at this point, to the recommended assemblytorque, completes the assembly.The sharp torque rise gives a solid feel at assembly, andminimises the possibility of over tightening.Because the sealing surfaces are flat and perpendicular tothe assembly forces, they remain virtually free of distortionduringassembly,givingO-LokPlusfittingsvirtuallyun-limitedremakeability.
