Heat shrink tube Ergom TGR 52 / 20 mm, 1 m length

Ergom TGR 52 / 20 mm heat shrink tube, 1 m length, is a flexible polyolefin sleeve engineered to provide electrical insulation and mechanical protection where cable diameter needs to be reduced. The tube shrinks from 52 mm to 20 mm, creating a tight, protective covering for splices, joints and areas requiring strain relief. It improves resistance to moisture and abrasion when applied with controlled heat, making it suitable for electrical, telecom and general wiring tasks.

Advantages

The heat shrink tube offers predictable shrink ratio and a consistent final diameter for reliable coverage of cable transitions. Its construction provides mechanical reinforcement, protection against abrasion and increased moisture resistance. The product is delivered in a 1 m length for flexible use and straightforward cutting to required sizes, and it installs quickly using a heat gun or other controlled heating methods.

Suitable for

• Cable repairs and splice protection
• Sealing electrical and telecom connections
• Providing strain relief where cable diameter changes
• Mechanical protection against abrasion and light impact

Key specifications

• Material: cross-linked polyolefin (heat-shrinkable polymer)
• Initial outer diameter: 52 mm
• Final outer diameter after shrinkage: 20 mm
• Shrink ratio: designed to reduce from 52 mm to 20 mm
• Length: 1 m
• Properties: electrical insulation, moisture resistance, abrasion protection
• Activation method: heat (heat gun, hot air)

How to use

Measure and cut the required length of the heat shrink tube, allowing overlap on both sides of the joint or splice to ensure full coverage. Slide the tube into position before making the electrical connection where possible, then apply heat evenly with a heat gun or other controlled hot-air source. Move the heat source slowly along the tube without prolonged focus on a single point to avoid overheating; the tube will contract uniformly until it conforms to the underlying profile. Allow the tube to cool to ambient temperature before subjecting the assembly to mechanical strain or testing.

Usage recommendations

Use a regulated heat gun with adjustable temperature settings and keep a safe distance to prevent scorching. For applications requiring enhanced moisture sealing, consider using adhesive-lined heat shrink variants or applying appropriate sealing compounds where compatibility is confirmed. Avoid direct open flame and ensure ventilation during heating.
