The Kee Lite Fitting
The
simple but effective engineering principle of the Kee Lite Fitting is the foundation of
the most versatile pipe connection system available. There are many variations of fitting
to suit wide-ranging applications, providing the versatility to achieve virtually any
structural configuration.
Kee Lite Fittings are high grade aluminum
silicon magnesium alloy. A range of fittings to suit four sizes of pipe is available. A
simple hexagon key is the only tool required to create a strong, rigid joint. A recessed
set screw, tightened by the hexagon key, firmly locks the pipe into the fitting. The set
screw is manufactured in case hardened steel and is Kee Koat® protected against
corrosion.
A Kee LIte Fitting (size 6 to 9) has a
minumum slip load capacity of *1700 lbs. per set screw with the set screw tightened to a
torque of 29 lbs. ft. on aluminum schedule 40 pipe. The minimum slip load capacity
increases to *2000 lbs. when used with steel pipe. This is normally obtained when the
screw is fully tightened using a ratchet wrench.
Minimum material UTS: 33,000 PSI. All Kee
Lite Fittings undergo independent testing to assure quality and reliability.

Specifying Kee Lite Fittings
The information on fittings in this site is comprehensive, and because of the coding
system we have adopted, easy to use.
Diagrams are shown for each fitting showing
entry of tube/pipe, a table of dimensions and a definition of use adjacent to its
appropriate Type number (L10, L15, L20, L25 etc.).
Alongside the Type number is a code (6, 7, 8
or 9) relating to the outside diameter of the tube/pipe for which the Kee Lite Fitting had
been designed. The relationship between the Kee Lite tube/pipe reference and standard
tube/pipe outside diameter is explained in the aforementioned chart.
Example: (1) A L10-7 is a Type L10 Kee Lite
fitting with both sockets designed to accept a tube/pipe that has an outside diameter of
42.4mm or 1 11/16" (1 1/4" Nominal Pipe Size). (2) A L25-9 is a Type L25 Kee
Lite fitting with all three sockets designed to accept a tube/pipe that has an outside
diameter of 60.9mm or 2 3/8" (2" N.P.S.).
While Kee Lite can give a general guidance
relating to the use of each Kee Lite fitting detailed in this site, the nature of the
product means that the ultimate responsibility for selecting the correct fitting for an
application must lie with the customer.
The customer should also ensure that the
existing structure to which the Kee Lite construction is being secured, is of sufficient
strength to support both the self weight of the Kee Lite construction and the imposed
loads applied, including wind loads, snow loads, and any other superimposed loads.
