TE Connectivity Raychem MWTM Medium Wall Heat Shrink Tubing (16/5-1500)
Based on the product styling from the Raychem MWTM series documentation, this product is a Raychem MWTM medium wall, heat shrinkable insulation sleeve manufactured by TE Connectivity.
Engineered primarily for low voltage power electrical installations, distribution networks, and control panels, the MWTM 16/5 sleeve provides maximum protection against moisture ingress, environmental weathering, and mechanical abrasion. It pairs a tough cross linked polyolefin material with an internal hot melt thermoplastic adhesive layer to deliver an absolute watertight seal over power cables, joints, and termination lugs.
Key Features
-
Advanced Cross Linked Polymer Compound: Fabricated from high performance radiation cross linked polyolefin. This structural formulation ensures it will not melt or flow at elevated operating temperatures, providing robust mechanical strength and structural wear resistance.
-
Co Extruded Hot Melt Adhesive Lining: Equipped with an internal thermoplastic adhesive sealant. When shrunk using an industrial propane torch or hot air blower, the adhesive flows into surface scratches and cable gaps to establish a permanent moisture barrier.
-
Flexible 3:1 Shrink Ratio: Features an optimal expansion and recovery profile that allows the unrecovered sleeve to pass smoothly over standard terminal fittings, lugs, or connectors and shrink tightly onto smaller cable diameters.
-
Excellent Electrical Insulation Properties: Provides a high dielectric strength rating, satisfying international low voltage utility requirements for primary insulation jackets up to 1 kV.
-
UV and Weathering Immunity: Highly resistant to continuous outdoor ultra violet (UV) light exposure, chemical splashes, ozone breakdown, and soil alkalis, making it ideal for direct subterranean burial.
Sizing and Dimensions
The MWTM 16/5-1500 model configuration follows standard engineering dimensions tailored for small to medium wiring profiles:
-
Minimum Supplied Internal Diameter: 16 mm (unshrunk internal space width)
-
Maximum Recovered Internal Diameter: 5 mm (fully recovered tight grip space after heating)
-
Total Pre Cut Length: 1500 mm (1.5 meters continuous strip length)

Applications
-
Low Voltage Cable Jointing: Serves as the primary dielectric insulation jacket and environmental moisture seal over inline cable joints up to 1 kV.
-
Conductor Sheath Repair: Instantly patches deep insulation scrapes, nicks, and jacket tears on low voltage control or power instrumentation lines.
-
Environmental Sealing at Terminal Lugs: Shrunk tightly over the back ends of termination lugs to block moisture from entering the exposed copper strands.
-
Industrial Automation Routing: Protects sensor cables, limit switch loops, and actuator power leads inside automated assembly lines against water washdowns and grease exposure.
