New: Parker's EO-3® Flareless Fitting Visually Confirms Completed Tube Assembly

Posted on Thu, Sep 28, 2017 @ 11:33 AM

Factors like fluctuating or inexperienced personnel, shortage of skilled workers and increasingly difficult installation conditions can lead to tube assemblies being incorrectly installed. The results are leaks, costly downtime and inefficiency, as well as increased safety risks. Driven by the customer desire for simplified fitting technology, Parker developed the innovativeEO-3® flareless fitting system. Utilizing a special tapered thread and visual status recognition, it speeds tube assembly and improves assembly accuracy.

Parker EO-3 Visual Check of Full Assembly

An industry first, EO-3 fittings feature a unique threading technology and indicator ring to make tube assembly outcome visibly discernable from the outside. Eliminating leakage due to inadequate tightening, EO-3 flareless fittings boost reliability and safety, and minimize rework.

How Parker's EO-3 Tube Fitting System Works

Port assembly by “feel” is inadequate, leaving too much room for costly and dangerous errors. Many times these errors are not discovered until final inspection or delivery. The EO-3 fitting system provides clear tube assembly status with visual recognition. This puts the user in control of making high-precision, high-quality connections fast.

Parker F3 WorkCenter

Form the new EO-3 connections with the proven F3 WorkCenter, a fully automatic machine featuring high performance hydraulic drive and robust forming tools. When contructed using the F3 WorkCenter, EO-3 tube ends provide a fast, consistent and reliable method of tube preparation. In fact, compared to typical DIN 2353 cutting ring designs, the EO-3 end-forming process helps prevent tube failure due to incorrect presetting.
