Aluminum Conduit, Couplings, and Elbows
Allied Tube & Conduit, the leading manufacturer of
steel conduit and tubing, also offers a broad line of
rigid aluminum conduit, couplings, and elbows.
Allied aluminum rigid conduit combines light weight and
corrosion resistance to provide a full-line of easy to
install, low maintenance conduit whenever specifications
call for aluminum.
Allied rigid
aluminum fittings are
manufactured of
6063 alloy in temper
designation
T-1.
FEATURES
• Light Weight Rigid Aluminum Conduit is
approximately one-third the weight of steel.
•
Corrosion Resistant Aluminum resists most
corrosive atmospheres in industrial
environments.
• Easy to Install Aluminum Conduit can be easily
cut, bent and threaded without special tools.
• Low Maintenance Aluminum Conduit does not
corrode or leave discoloring streaks or stains.
RECOMMENDED INSTALLATION
PRACTICES
CUTTING:
A hacksaw is recommended to cut trade sizes 1
1
/
4
and smaller.
Larger trade sizes can be cut with power cut-off equipment.
BENDING:
Standard EMT benders, one size larger than the size of the conduit,
should be used on conduit trade sizes 1 and smaller. For sizes over
trade size 1, conventional equipment is recommended.
THREADING:
Sharp dies and conventional cutting oil should be used for aluminum
conduit. A general purpose emulsifiable oil can provide excellent results.
FITTINGS:
Aluminum fittings are recommended; however galvanized fittings
are satisfactory for most installations.
FISHING AND WIRE PULLING:
Small Conduit:
In trade sizes up to 1
1
/
2
and on shorter runs (up to 100 feet),
polyethylene fish tapes can be used effectively. Also recommended
are round, flexible, speedometer-type steel cables. Use of flat steel
tapes should be avoided since they tend to jam in the bends, or
if not used carefully, scrape and cut conduit walls.
Large Conduit:
For pulling large conductors through larger conduit or longer runs,
polypropylene rope is recommended. Steel pulling cables, especially
when old or frayed, can damage steel or aluminum conduit.
IN SOIL OR CONCRETE:
Underwriters’ Laboratories Electrical Construction Equipment
Directory (UL Green Book) states that aluminum conduit used in
concrete or in contact with soil requires supplementary corrosion
protection. Examples of supplementary protection are paints
approved for the purpose (bitumastic paint, for example), tape
wraps approved for the purpose, or PVC coated conduit.

SPECIFICATION DATA
ALLOY: Allied Rigid Aluminum Conduit is manufactured of
6063 alloy in temper designation T-1. The fittings are of the
same alloy.
STANDARDS: Allied Rigid Aluminum Conduit is listed by
Underwriters’ Laboratories to U.L. 6A, “Standard for
Electrical Rigid Metal Conduit — Aluminum, Red Brass and
Stainless Steel” and is manufactured to ANSI C80.5.
(Replaces Federal specification WWC-540C).
THREAD PROTECTORS: Color-Coded end caps keep
threads clean and sharp and help provide trade size
recognition. Even sizes are blue; 1/2 trade sizes are black;
and 1/4 trade sizes are red.
Weights and Dimensions for Rigid Aluminum Conduit
NOTE:
• Dimensions and weights are nominal unless otherwise noted.
• Each length of conduit with coupling attached will be nominally 10 feet.
