Ultra Spec's Cleaning Swabs help to eliminate contaminants on the ferrule end faces, inside the plug of fiber connectors and adapters and the alignment sleeves. This helps to maximize your network's performance and save you time and money by preventing service calls for contaminated connectors and by extending the life of the cable as a result of routine maintanance. Since it's designed for all general cleaning applications, you may use the swab dry, due to its soft, pharmaceutical grade cotton tip or wet, since its absorbent head is compatible with most solvents. Each pack includes 100 easy to use swabs that are compatible with 1.25mm LC and MU connectors and adapters. We also offer the 2.5mm size for SC, ST and FC connectors and adapters.
