DNC - Dual Layer Cold Shrink Silicone Rubber Sleeve

Applications:

DNC is made of highly weather-resistant Silicone rubber material. The product and construction quality are improved through the dual-layer design of the built-in rubber ring. It is widely used in various types of cable joint protection for coaxial cables, jumpers, DIN connectors, connectors, N-type connectors, etc. of communication base stations.
Simple and convenient operation methods can be rapid construction without using tools in a narrow environment that does not allow fire sources. The new adhesion ring structure of the inner layer can improve the hardening issues of traditional mastic, and make the protection ability of waterproof insulation and sealing more reliable and durable.
