Heat-Shrink Sealing Cap CellPack Kapturek EC 75 (MPN 5-3015) 75 mm

CellPack Kapturek EC 75 is a heat-shrink sealing cap engineered for insulation and environmental protection of cable ends and connectors. The EC 75 model provides a 75 mm diameter shrinking range and creates a tight, moisture-resistant barrier when heated, making it suitable for electrical installations, cable repairs and outdoor terminations that require both mechanical protection and reliable sealing.

Advantages

The heat-shrink material conforms to varied cable and connector shapes, delivering uniform shrinkage and a secure fit. Once applied and heated, the cap forms a durable, moisture-resistant seal that reduces the risk of corrosion and electrical faults. Its form-fitting design simplifies installation, reduces the need for additional sealing compounds and offers long-term environmental protection against dust, water ingress and mechanical abrasion.

Suitable for

• Sealing cable ends and connector housings in outdoor and indoor electrical installations
• Repairing damaged cable terminations and insulating exposed conductors
• Protecting splices and connectors from moisture and contaminants
• Applications requiring mechanical protection and weatherproofing

Key specifications

• Shrink diameter range: designed to fit components up to 75 mm before shrinkage
• Material: heat-shrink polymer providing tight, conformal fit and moisture resistance
• Function: environmental sealing and mechanical protection for cable ends and connectors
• Application environment: suitable for indoor and outdoor use with weather-resistant properties

How to use

Slide the Kapturek EC 75 over the cable end or connector so the part to be sealed is fully covered. Apply heat evenly using a suitable heat gun or other controlled heat source, moving the heat source around the cap to ensure uniform shrinkage. Continue heating until the cap has fully contracted and formed a tight seal around the component; avoid overheating by keeping the heat source moving and monitoring material behavior. Allow the seal to cool and inspect visually to confirm full adhesion and absence of gaps.

Usage recommendations

Ensure the working area is clean and dry before application. For best results use a regulated heat gun at moderate distance to achieve even shrinkage. When sealing critical or high-voltage connections, follow applicable safety standards and perform post-application inspection and testing to verify electrical integrity and environmental protection.
