EMA couplings provide easy diagnostic connections for Parker

Ā®
equipment or mechanical gages. EMA test
points are typically permanently plumbed into a fluid system
at locations where pressure measurements are required for
maintenance or testing. Integral pressure cap protects the test
point from damage and prevents contam-ination of the fluid
system. Proven twist-to-connect design allows the test points
to be connected even when the system is in operation and the
test points are pressurized. EMAās compact design and optional
high pressure hose assemblies allow extra flexibility for the
location of system test points.
Although designed primarily for diagnostic applications, EMA
fittings and hose assemblies are idea for a wide range of
applications that require compact high pressure connections
and limited flow rates.
Features
ā¢ Knurled sleeve allows simple twist-to-connect operation
without the use of tools
ā¢ Rugged design allows connect-under-pressure operation up
to 5800 psi
ā¢ Maximum rated working pressure of 9000 psi exceeds the
requirements of most applications
ā¢ Integral threaded dust cap protects the test point from
damage and contamination
ā¢ EMA fittings are machined from solid barstock and protected
with Chromium-6 Free plating.
ā¢ Stainless steel springs for corrosion resistance
ā¢ Elastomeric interface and valve seals provide leak free
operation
ā¢ Compact design and optional high pressure hose assemblies
provide flexibility for tight space requirements
