Lindab Safe Connection
The Lindab Safe self-sealing duct system is based on a U-profile, EPDM rubber gasket. This gasket is located in a groove at the end of the fitting and is securely attached by an stainless steel band. This design ensures that the rubber gasket is always held in the correct position.
When the fitting is inserted into the spiral duct, the gasket folds back forming a seal against the inside of the spiral duct eliminating the need for any duct sealer.
In order to achieve optimum sealing for all diameters, various gasket sizes are used as shown in the table below.
The standard Lindab Safe gasket is made from a material resistant to ozone, UV rays, and temperature fluctuations. A silicone gasket for special applications is also available. The standard Lindab Safe gasket is rated for tempera-tures from -20F to +212F (silicone gasket rated for temperatures from -94F to +302F).

Duct System Leakage Classification
The graph below represents a selected series of leakage classes as defined by the formula CL=F/P0.65. The formula defines leakage class as the relationship between leak rate, duct surface area, and pressure.
Since the calculation of leakage class is based on several relevant factors while percent leakage is based only on overall system air flow, leakage class is a more comprehensive method of assigning allowable leakage rates. This enables the designer to address all major system factors by simply assigning a leakage class.
Lindab Safe meets SMACNA's Leakage Class 3 requirements without the use of any duct sealants.
F = Leak rate per unit of duct surface (cfm/100 sq. ft.)CL = Leakage Class P = Static pressure (iwg)

Assembly InstructionsPreparations for assemblyCheck that ducts and fittings to be used in the system are Lindab Safe and are undamaged. All Lindab Safe fittings must be used with calibrated spiral duct certified by Lindab.
Do not use ducts or fittings that have been damaged in such a way that they jeopardize the air tightness or structural strength of the system.
Store ducts and fittings in a well-ordered and weatherproof storage area to minimize the risk of damage.
Cut ducts at right angles. Carefully remove any burrs from cut edges. Installation is easier and the risk of damaging the gasket is reduced if there are no burrs.
AssemblyStart by inserting the turned-over edge of the fitting into the duct.
Check that the first lip of the gasket is in contact with the edge of the duct all the way around and sticks straight out so that the lip is not twisted in one direction or the other.
Push the end of the fitting into the duct. Turning the fitting slightly aids insertion. (Removal, if necessary, is also aided by turning.)
Secure the fitting in the duct using self-tapping screws or airtight pop rivets.
Fasteners should be positioned 1/2" from the bead to prevent damage to the gasket.
Placement of the fastening screws should be opposite from one another evenly spaced around the circumference, much like the procedure for tightening lug nuts on a tire (see diagram). Start where the distance between the duct and the fitting is largest. Screws should be placed approximately 1/2" from the bead in order to avoid damaging the Lindab Safe gasket. In the event of incorrect installation, holes caused by screws or pop rivets must be sealed before reassembly.
Quantities and sizes to be used are listed in the below table.
Duct Dia. Screw Dia. Quantity
(inch) (inch)
3 - 5 26 - 10 3
12 - 24 426 - 50 652 - 60 8
Always start the first fastener at the largest radial gap between fitting and duct. Be sure to achieve even distribution around the circumference.
Carefully seal any holes left by measure-ments, removed screws, pop rivets, etc.

All spiral duct 8" diameter and larger shall incorporate multiple corrugations between spiral seams.B. Fittings shall be manufactured using one or more of the following construction methods: Overlapped edges stitch welded along the entire length of the fitting Standing seam gore locked and internally sealed Button punched and internally sealed Elbows 3" through 12" diameter will be die stamped and continuously stitch welded.
CONNECTIONSFitting ends shall be sized to slip-fit into spiral duct of the same nominal size. Fitting to fitting connections shall be made by use of duct size MF couplings. Duct to duct connections require fitting size NP couplings.
JOINT SEALINGFitting ends are equipped with factory installed, double-lipped, U-profile gaskets. When installed in spiral duct per man-ufacturers installation instructions, the gasket creates a seal against the interior of the spiral duct. The system tightness shall be factory warranted to meet SMACNA's Leakage Class 3 performance. If no gasket is used, all joints must be sealed by the installer during the installation process. The type of sealant used as well as the method and level of application should be as directed by the specification and in accordance with the sealant manufacturers published installation instructions.
GASKET The gasket shall be EPDM rubber. The gasket is located in a groove at the end of the fitting and securely fastened by means of a stainless steel band. In order to achieve optimum sealing for all diameters, different size gaskets shall be used. The gasket shall be classified by Underwriters Laboratories for flame spread and smoke developed in accordance with ASTM E84-91a. A silicone gasket meeting the same performance may be offered by duct manufacturer for special applications.
