Parker EO-3 Fitting System
®
World’s first visual assembly status recognition
EO-3 Innovative Technology at a Glance
Specifications
•Standard series classification: LL, L and S
•Common tube outside diameters: 6.0 mm to 42.0 mm with commercially available tube wall thickness
•Pressure rating: up to 6,000 psi (420 bar) for all tube sizes
•Fitting material: steel with chromium 6 free plating
•Tube material: conventional hydraulic steel, e.g. E235 (ST37) or E355 (ST52.4) standard to DIN EN 10305
•Elastomer material: NBR
•Temperature resistance: -40° to 248°F (-40° to 120°C)
•Media compatibility: analogous to NBR material
The EO-3® fitting system is a robust, flexible offering
for tube applications. Featuring the new Parker tapered
thread design, it is capable of exactly matching
flank and taper dimension to assembly performance
(i.e. stroke and force), as well as the tear-out and
shear resistance of a tube connector.

Just what the world of technology has been waiting for
Factors like fluctuating or
inexperienced personnel, shortage
of skilled workers and increasingly
difficult installation conditions can
lead to failed assemblies. The results
are costly downtime and inefficiency,
as well as increased safety risks.
Driven by the customer desire for
simplified fitting technology,
Parker developed the innovative
EO-3® fitting system. Utilizing visual
status recognition, it speeds assembly
and improves accuracy.
An industry first, EO-3 fittings feature
a unique threading technology and
indicator ring to make assembly
outcome visibly discernable from the
outside. Eliminating leakage due to
inadequate tightening, EO-3 fittings
boost reliability and safety, as well as
minimize expensive reworkings.
Manufactured from steel, EO-3
fittings withstand temperatures of
-40 to 248°F (-40 to 120°C), and
have a maximum pressure rating
of 6,000 psi (420 bar) for all tube
sizes. They perform in a wide range
of applications, including:
• Energy
• Agriculture
• Paper machinery
• Oil and gas extraction
How it Works
Assembly status recognition offers necessary support
Assembly by “feel” is inadequate,
leaving too much room for costly and
dangerous errors. And, many times,
these errors are not discovered until
final inspection or delivery.
The EO-3 fitting system provides
clear assembly status with visual
recognition. This puts the user in
control of making high-precision,
high-quality connections – fast.

EO-3 Weldless Tube Lines
Simplify tube preparation with energy-efficient forming technology
EO-3 connections are formed 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.
