Great for protecting the connectors on our indoor power extension and indoor power splitter cables from water, chemicals and dirt allowing them to be used outdoors! This small piece of black dual-wall heat shrink tubing is 1-inch long and has a 0.5-inch non-recovered diameter and 1/8-Inch recovered diameter. The tubing has an adhesive lined inner wall that activates once heated and creates a tough water, dirt, and chemical resistant bond after recovering from being heated. The tubing has a large 4:1 heat-shrink ratio allowing for a snug fit over rough and uneven surfaces. This piece of heat-shrink tubing is the perfect length and diameter to fit over our indoor 5.5mm x 2.1mm barrel connectors to create a water, chemical and dirt resistant barrier. It will also work with connections between an indoor 5.5mm x 2.1mm barrel connector and an outdoor (IP66 rated) 5.5mm x 2.1mm barrel connector with M12-1.75 threads. This tubing can also be used for other types of connectors such as adapters used to convert from 5.5mm x 2.1mm barrel connectors to USB and other types of miniature connectors. The tubing can be shrunk using a heat gun, a hair dryer and even an open flame from a lighter or a match. Made of flame-retardant materials.
