TIZIP Easy - waterproof zipper, 250 mbar

The technical principle

The TIZIP Easy is made from a strong, plastic coil zipper on a high strength fabric. Every coil half is safely embedded and secured in a plastic profile.

When the TIZIP Easy is closed the sealing lips above and below the coil are compressed making a perfect seal. The entire plastic profile is highly abrasion resistant. The unique design prevents the slider from wearing down the sealing lips when the zipper is opened or closed.

The physical design of the TIZIP Easy increases the seal strength when the pressure is raised or when cross tension is applied. Both actions lead to an increased mechanical pressure on the top sealing lip.

Tightness

The TIZIP Easy will hold 250 mbar air pressure. The TIZIP Easy is slightly less airtight than the TIZIP SuperSeal but is easier to operate. Heavy bending may cause leakage. Please try to avoid!

Dirt or Sand

The TIZIP Easy is highly resistant to damage caused by dirt or sand. However if dirt or sand are present, the zipper should be cleaned with soap and water. Dirt particles can affect the sealing function if they get caught between the chain profiles. If the TIZIP Easy closure is used to protect life or sensitive material, the sealing function and cleanness of the chain area should be double checked prior to every usage.

Stability

The TIZIP Easy´s performance in terms of strength and durability is outstanding. It can take weight, it is abrasion resistant and it will survive short term sharp bending and twisting without separating.

Testing

The sealing function of the TIZIP Easy is tested by fastening the zipper in a straight rectangular frame, 3 cm wide, face down. Compressed air is applied to the front side of the zipper and water poured over the back until it is submer-sed. To pass the test no air bubbles may occur for a period of 20 seconds. Random testing is performed during the production of every batch.

However, in the event the TIZIP is over-stressed during closing, the chain may stay separated. In this case, simply move the slider back, reduce the cross tension, then reclose the zipper. The TIZIP will not be damaged by this procedure.

Lubrication

Prior to installation in a product, no lubricant is applied to the TIZIPs. However, lubrication is essential to maintain the ease of operation and proper coupling of the chain. After installation into a product, manufacturers are requested to lubricate the TIZIP all along the chain tips, and to operate the slider the full length of the chain, in both directions, at least 5 times. Acid free, grease or oil lubricants may be used.

Initial lubrication and operation is essential for the full strength of the seal!

If the chain is dry, re-lubricating by the user is recommended from time to time (apx. every 10 uses ).

Please see the instruction card and lubricant tube supplied with each TIZIP. Lubricating the outer flanges of the sealing profile reduces the sliding force greatly.

Versions

both ends closed		open top

• Width: 50 mm und 70 mm
• Chain width: 11mm
• Extensions over end stop and docking end: 16 mm or 25 mm

Operating Force

For the sealing function the TIZIP Easy requires a fairly strong pull of the slider. Please allow a slightly higher pulling force as compared to regular zippers. A wet surface or lubricant on the outer flanges of the sealing profile reduces the pulling force greatly.
