Tech Tip: The Importance of Changing End Seals

Many technicians try to save a dime or two by using the same end seal for an overly extended period of time, but those technicians may not know that by over using an end seal they are compromising the quality of the repair and likely wasting resin. By changing out the white end seal at the bottom of the Delta Kits 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. Not to mention, 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, even though this may result in wasted resin, and makes it difficult to ensure that the damage is filled. Continue Reading
