3M 7000005985 Medium-wall Heat Shrink Cable Sleeve Mdt

Product Description

The 3M 7000005985 is a medium-wall, heat-shrinkable cable sleeve in the MDT series, manufactured from split-resistant cross-linked polyolefin with a factory-applied thermoplastic adhesive and sealant lining. Each sleeve measures 48 inches in length and is designed to protect cable splices, terminations, and wire bundles against mechanical damage, moisture, corrosion, and chemical exposure. The sleeve is flame-retardant and carries an internal adhesive that softens during heat application, bonding to underlying surfaces and filling small voids to create a reliable environmental seal. Electrical contractors, telecom technicians, and utility crews install these sleeves wherever durable, long-term cable protection is required.

The MDT series is suited for residential, commercial, and industrial wiring applications where an intermediate level of wall thickness is appropriate. MDT sleeves are more flexible than the heavier-wall HDT series, making them a practical choice in congested cable trays, junction enclosures, and outdoor splice points. The unprinted, 48-inch length allows field trimming to fit a wide range of cable diameters. This SKU ships in cases of 20 sleeves, with a minimum order quantity of 15 units as noted by the supplier.

Key Features

• Cross-linked polyolefin construction resists splitting, abrasion, and chemical attack
• Flame-retardant rating suitable for code-compliant electrical installations
• Factory-applied thermoplastic adhesive and sealant bonds and seals during shrink process
• Greater flexibility compared to heavy-wall HDT series for easier routing in tight spaces
• Fast-shrinking design reduces installation time with minimal training required
• 48-inch unprinted length allows field trimming to match expanded inside diameter needed

Compatibility

Designed as an OEM-style protective sleeve for cable splices, terminations, and wire bundles across electrical, utility, and telecom applications. Select the sleeve size based on the expanded inside diameter required for the target cable or connector.

Installation Notes

Installation is performed by qualified electricians or telecom technicians following applicable NEC or site-specific wiring codes. De-energize all circuits completely before placing the sleeve over any conductor or splice. Apply heat evenly along the sleeve using a calibrated heat gun, working from the center outward to allow the adhesive to flow and seal uniformly. Do not use an open flame as a heat source, as uneven heating can prevent proper adhesive bonding and dimensional recovery.
