Applications:
UNY and UNF unions are installed in
threaded thick wall conduit systems:
• UNY – to connect conduit to a conduit
fitting, junction box or device enclosure
• UNF – to connect conduit to conduit, or to
provide a means for future modification of
the conduit system
UNA unions are used in conduit and fitting
installations when entrance angle is between
90° and 180°.
EL elbows are installed in conduit run or in
box or fitting hub:
• To change direction in threaded rigid
conduit run by 90°, or when terminating at
a box or fitting
Features:
UNY, UNF and UNL unions have:
• Compact design which permits assembly
with a minimum of clearance to other
adjacent conduit and/or equipment
• Strong and durable construction
UNA unions:
• Have a single clamping nut on angle,
making it both a union and a connector
• Permit conduit joints at angles between
90° and 180°
EL elbows have a smooth interior and are
both strong and compact.
Standard materials:
• UNY, UNF unions – 1/2” to 1” and 11/2”:
steel
• UNY, UNF unions – 11/4” to 6”: Feraloy
iron alloy
• UNL, UNA unions – Feraloy iron alloy
• EL elbows – Feraloy iron alloy or ductile
iron

UNY and UNF unions –

Applications:
UNY and UNF unions are installed in
threaded thick wall conduit systems:
• UNY – to connect conduit to a conduit
fitting, junction box or device enclosure
• UNF – to connect conduit to conduit, or to
provide a means for future modification of
the conduit system
Features:
UNY and UNF unions have:
• Compact design which permits assembly
with a minimum of clearance to other
adjacent conduit and/or equipment
• Strong and durable construction
Stainless steel benefits:
• Self-healing properties help reduce the
penetration of rust/corrosion and eliminate
damage to the fitting
• Retain strength in extreme heat and
extreme cold conditions
• Surface is easy to maintain and keep clean
• Easy cleaning capabilities make these
fittings perfect for food processing and
other hygienic areas where wash downs
are common
• Superior strength and durability greatly
reduce replacement – this will lower your
total cost of ownership and increase your
return on investment
• Do not require harsh environmentdamaging cleaners to keep them looking
like new
