Specifications for Tite-Seal Leak Lock Plugs

The Leak Lock system is a two piece system which is used when the octagon flange gasket has been incinerated during the burning operation of the reconditioning process.

This plug replaces the traditional three piece system that uses a gasket, retaining ring, and hexagon plug.

The Leak Lock system alleviates the problem of alignment, therefore saving you time and assuring your customer a quality seal. This system is the simplest and most effective on the market to prevent flange leakage due to drum incineration.

Tite-Seal S-insertion of Octagon Base Drum Flanges

Technocraft Industries and Con-Tech International announce the innovative Tite-Seal Brand S-Insertion of Octagon Base flanges. This new method of inserting flanges into drums provides the most secure closure available on the market today.

Technocraft Industries, with almost 30 years'experience producing drum closures, is a world leader in the drum closure industry. Through its advanced R&D efforts, the company has developed the new S-insertion method of installing flanges into steel drums.

The S-insertion method starts with the standard process of punching and forming the pocket for the flange and then installing it into the drum. The patented advancement that the S-insertion provides is the crimping of the pocket around the flange. This crimping operation pushes the metal at the bottom of the pocket under the flange, thus locking the flange into the pocket.

With normal insertions, in drop tests where the head of the drum falls flat on the ground, the flange is pushed out of the pocket. Leakage of the closures results. With our new S-Insertion method, perpendicular flat drop tests do not result in flanges jarred from the pocket.

The advantages of this innovative flange insertion method are:

• No change or increased cost of the flanges
• No additional or thicker gasket on the flange is required that results in increased costs to manufacture
• No change in closure procedures are required by the drum filler
• The flange remains firmly seated in its pocket, unlike the standard flange insertions when drums are dropped perpendicular to the floor. The only change required is a tooling modification at the drum manufacturer's plant.

To insure the safest, securest package available today, please consider specifying our S-insertion flange for your steel drum requirements.

Auto-Seal Closure System

Con-Tech International and Technocraft Industries are proud to introduce our new labor saving Auto-Seal Drum Closing System. This system can be customized to perform drum-closing functions for both drum manufacturers and packagers of drums.

Technocraft, as a result of its nearly 30 years producing closures for the drum industry worldwide, has developed this new system to automatically close drums. Each system is custom built to perform individual closing functions required by each client. Both drum manufacturers and drum fillers can significantly reduce manpower by using our Auto-Seal System.

Drum Packagers

Our Auto-Seal Closure System can be customized to perform automatically any or all of the following functions:

• Remove plugs from drums prior to filling
• Purge drums with cool, dry air or an inert gas
• Apply a nitrogen blanket to the drum after filling
• Automatically install the plugs into the drum
• Precisely tighten the plugs to the required torque
• Automatically apply and crimp the cap seals

Our Auto Seal System can perform all of the above functions automatically, thus reducing manpower requirements significantly. More importantly, when hazardous materials are being packaged, utilizing our Auto Seal System eliminates the dangers to personnel who would normally be in close proximity to the packaging operation.

Drum Manufacturers and Reconditioners

Numerous functions can be performed by the Auto-Seal System in the plants that produce or recondition drums. Our system can be installed in one or more sections of plants, depending on where these functions are performed. Closing operations that can be efficiently handled are as follows:

• Purging of drum with cool, dry air
• Helium injection for helium testing
• Inserting both the round head and hex head plugs, 2" and 3/4"
• Precise torquing of plugs
• Application and crimping of 3/4" cap seals
• Insertion of paint plugs, prior to painting
• Removal of paint plugs, subsequent to painting
• Orientation of drum prior to silk screening

Whether you make drums or fill them, the Auto-Seal Closure System can increase your efficiency and profits. For additional information, quotations, etc., please contact us at
