An electrofusion end cap is a fitting that seals the termination of a polyethylene pipe by using an integral electric heating coil to melt and fuse the cap directly onto the pipe, creating a permanent, leak-proof closure.

An electrofusion reducing coupling connects two polyethylene pipes of different diameters in a straight line by using an embedded heating coil to melt and fuse the fitting to both pipes, creating a strong, leak-proof transition.

An electrofusion reducing tee connects three polyethylene pipes (one branch line at a reduced diameter) by using an embedded electric heating coil to melt and fuse the fitting to the pipes, creating a leak-proof joint.

A gasket seals the joint between two surfaces to prevent leakage of fluids or gases.

The durable wire mesh skeleton pipe is a composite pipe that encases a welded steel wire mesh within HDPE layers, combining the corrosion resistance and light weight of plastic with the strength and rigidity of steel. It eliminates rust, scaling, and leakage, withstands high internal pressure, external loads, and ground settlement, and offers exceptional long‑term durability. Used for conveying water, gas, chemicals, and slurries in municipal, industrial, mining, and irrigation systems, it provides a reliable, maintenance‑free, and cost‑effective alternative to traditional metal and pure plastic pipes.

Anti-aging air holes suitable for optical cables are specially designed ventilation openings made from weather-resistant, anti-aging materials that allow controlled air circulation within optical cable ducts or closures. Their primary function is to balance internal and external pressure, effectively preventing moisture condensation, water ingress, and heat buildup that could degrade fiber performance. By maintaining a dry and stable environment, they significantly extend the service life of optical cables, reduce signal loss, and minimize maintenance needs, making them an essential protective component in outdoor telecommunication, FTTH, and long-haul fiber optic networks.
