Tech Tip: The Importance of Changing End Seals

Many windshield repair technicians try to save a dime or two by using the same end seal over and over. But those technicians may not know that by over using an end seal, they are compromising the repair quality. It is likely wasting expensive resin. Changing end seals, the little off-white cylinder, at the bottom of the Delta Kits’ resin injector, technicians can ensure that repairs are done correctly and efficiently.

For best results, Delta Kits recommends replacing the injector end seal after every 10 repairs or sooner if there is a noticeable change in pressure or resin leakage around the seal. After 10 uses, the end seals begin to break down and get softer. The inside diameter of the end seal is smaller than the plunger to provide a leak free seal. After repeated use, the hole becomes enlarged, eventually resulting in loss of pressure. Loss of pressure can create leakage of resin, which results in wasting resin, and makes it difficult to ensure that the damage is filling with resin.

Restoring the structural integrity of the windshield should be the single most important goal of every windshield repair technician. Replace your end seals every 10 repairs. Make it that much easier to restore the integrity of the glass.  Ultimately, saving yourself time (time is money). You will also save on resin cost by reducing waste.
