Cold Shrink Tube 17.5-33.0mm | Length 305mm
3M 8427-12 is a pre-stretched EPDM rubber cold shrink tubing that is factory expanded and assembled onto a removable core.
The tubes manufactured by 3M Electrical, utilise their Cold Shrink technology for simple and reliable mechanical sealing and electrical insulation of Low Voltage cables and connections – this ensures a permanent, durable environmental seal and insulation.
No tooling, such as jointers torches, are required with cold shrink tubing installation and it is able to cover a wide range of cable cross sections.
This pre-stretched cold shrink tubing is suitable as primary insulation on a range of 1000v cables with copper or aluminium conductors.
The core is removed from the 3M 8427-12 after the cold shrink tube has been positioned for installation over an inline connection, terminal or cable allowing the 3M tube to shrink and form a waterproof cable seal, repair or cable joint – no “hot-working” for hazardous areas and potentially explosive atmospheres.
3M 8427-12 is available ex stock, contact us for price, delivery or to place an order.
