Based on decades of R&D and real outside plant experience, our heat shrink closures are easy to deploy and last for prolonged periods of time. These splice closures help insulate, seal and protect your copper wireline network connections even in the harshest environments.
Deploying our closures means there are no unexpected surprises—no matter where you need them:
- Work with pressurized and non-pressurized networks
- Ideal for aerial, buried and ducted deployment
- Support many cable diameters and joint dimensions
- Technical support and services—from specifiers to field engineers
Our closures have a proven track record in telecom and other demanding applications, like railways. They’re made using an in-house adhesive with superior properties for cable fixing. Plus, they’re put through our stringent testing.
Additionally, a diverse range of heat shrink kits provides solutions for blocking, cable repair, cable end protection, and more.
Fueled by unmatched experience, we deliver inventive solutions tailored to your evolving needs.
IMPORTANT NOTE: By mid-2019, our heat shrink sleeves will no longer feature the Raychem name. But the innovative technology that goes into these products will remain the same.
