The premolded straight joint consists of a rubber block unit, insulation compound, a connector, and protective covers. The rubber block unit is premolded by using high-quality silicon rubber in the factory. It is pre-expanded with a spiral core in the factory and can be installed only by pulling the spiral core at the site. Therefore the special tools and high skill are unnecessary at the assembly process, so those shorten the assembly time and stabilize the product's performance.
According to the customer's requirements, a coffin box can be used optionally. The joint without coffin box can also meet waterproof requirements due to its protective copper tube with plastic waterproof coating.

So the stabile performance is demonstrated by more past records.
