The 1.25 mm (2316) and 2. 5mm (2317) wrapped foam fiber optic swabs are ideal for removing transmission disrupting contaminants in bulkhead connectors. The head conforms to the various connector shapes, cleaning the conductor bulkhead corners inside the bulkhead pocket. These swabs may be used wet or dry to remove dirt and oil contamination. Each swab is manufactured with superior proprietary foam; no glues are used in the manufacturing process, thereby minimizing leachable contaminants.
