Features
• Knurled sleeve allows simple twist-to-connect operation
without the use of tools
• Rugged design allows connect-under-pressure operation
up to 5800 psi
• Maximum rated working pressure of 9000 psi exceeds the
requirements of most applications
•
Integral threaded dust cap protects the test point from
damage and contamination
• EMA fittings are machined from solid barstock and
protected with zinc plating and a chromium 6 free finish.
• Stainless steel springs for corrosion resistance
• Elastomeric interface and valve seals provide leak free
operation
• Compact design and optional high pressure hose
assemblies provide flexibility for tight space requirements

Applications
EMA couplings provide easy diagnostic connections for
Parker SensoControl
®
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 pre
vents 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. EMA’s
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.
