The XAGA 1650 Series Copper Splice Closure is a heavy-duty, heat-shrink composite sleeve closure designed for buried or ducted non-pressurized copper networks requiring superior moisture and mechanical protection.
Originally developed by Raychem, later acquired by Tyco, and most recently produced by CommScope, the XAGA 1650 series was trusted worldwide for decades as the industry standard in copper cable joint protection.
Each closure features a fiber-reinforced, heat-shrinkable wraparound sleeve with a hot-melt adhesive inner coating, ensuring a long-lasting, watertight seal around the cable sheath. With capacities ranging from 25 to 3,600 pairs, it provides robust performance in challenging underground or duct environments.

Background & Continuity
In 2023, CommScope officially shut down its Belgium heat-shrink factory, leading to the discontinuation of the XAGA 500, 530, 550, and 1650 series closures. This created a supply gap for many telecom operators and contractors worldwide who relied on these proven solutions.
Tyheatshrink, as a leading heat-shrink products manufacturer in China with 40 years of experience, has stepped up to fill this gap. Our engineering team has meticulously reverse-engineered and optimized the XAGA 1650 structure to ensure full compatibility and performance equivalence with the original CommScope design.
We now supply OEM/ODM XAGA 1650 replacements for global telecom operators, distributors, and brand owners, providing consistent quality, shorter lead times, and significant cost savings.
