HDPE Butt Fusion Bend 45°
The HDPE Butt Fusion Bend 45° is a precision-fabricated fitting designed to change the direction of flow by 45 degrees in high-performance piping systems. Made from PE100 high-density polyethylene, it provides superior durability, flexibility, and chemical resistance. This fitting is ideal for applications requiring smoother directional flow transitions, such as water distribution, industrial piping, chemical processing, and irrigation systems. It is joined using the butt fusion welding method, ensuring a strong, leak-free, and long-lasting connection.
An HDPE Butt Fusion Bend 45° is a High-Density Polyethylene (HDPE) pipe fitting designed to change the direction of a pipeline by 45 degrees. It is joined to HDPE pipes using the butt fusion welding process, in which the ends of the pipe and the fitting are heated and fused together to form a permanent, leak-proof, and high-strength joint.

HDPE Electro Fusion Fittings
Electrofusion fittings are specialized HDPE components designed with embedded electric heating elements that, when energized, melt and fuse the fitting to the pipe surface. This technique provides a secure, leak-proof, and durable joint, making it ideal for high-pressure and critical pipeline applications. Electrofusion is especially preferred when working in confined spaces, where using large butt fusion equipment is impractical.
HDPE Butt Fusion Fittings
Butt fusion fittings are one of the most reliable and widely used types of HDPE pipe fittings. These fittings are joined using a butt fusion welding process, which involves heating the ends of both the pipe and the fitting to a precise temperature (typically around 200–220°C), then pressing them together under controlled pressure until they fuse into a single continuous piece. This results in a permanent, seamless, and high-integrity joint.
