Factors like fluctuating or inexperienced personnel, a shortage of skilled workers and increasingly difficult installation conditions can lead to failed assemblies and costly downtime as well as increased safety risks. Parker EO-3 fittings address customers' desire for simplified fitting technology. Utilizing visual status recognition, it speeds assembly and improves accuracy.

Parker's EO-3 metric flareless tube fittings feature a visual indicator system to ensure correct assembly and prevent over-tightening. Relying on assembly "by feel" leaves too much room for user errors that often are not discovered until late in the assembly inspection process. With EO-3 tube fittings, the assembly status is always clear with the yellow window that is integrated into the fitting connection ring. The user is in control and can achieve a high-precision, high-quality connection every time.
