Low Voltage Tubing
Super Seal low voltage adhesive lined tubing is available in both medium and heavy wall sizes.
Medium wall low voltage tubing (series GMW) is used for environmental protection of low voltage cable terminations and insulating connectors for low voltage straight-through joints, splices, and jacket repairs up to 1.1KV.
Heavy wall low voltage tubing (series GHW) is used for mechanical protection and outer sealing of underground straight-through cable joints, splices, and jacket repairs up to 36KV. They both have excellent resistance to weathering, UV rays, chemicals, and solvents and conform to the IEC 60684-3-247 standard and are available in multiple lengths and diameters from 1/2″ up to 7.8″.
