As a professional manufacturer with over 40 years of expertise in the field of pipeline system components, Haihao Group is proud to offer a wide range of high-quality products made from various materials. Recently, we produced a batch of uPVC and PVC pipe fittings for a domestic client, with a total order exceeding 500 pieces. These fittings include adapters, couplings, and union NPT fittings, all tailored to meet the client’s specific needs.

uPVC pipe fittings
Product Overview
The batch produced includes several types of pipe fittings designed to ensure secure and leak-proof connections in piping systems. The key products are:
1.Adapter: These fittings are used to connect pipes of different sizes or materials. They provide a smooth transition from one pipe diameter to another, ensuring a secure and efficient flow path.
2.Coupling: Used to join two pipes of the same size and material, couplings ensure a strong connection, allowing for the extension of pipelines without compromising the integrity of the system.
3.Union NPT Fitting (Internal Threaded Union): These fittings are designed with internal NPT threads, making them ideal for connecting pipes that require easy assembly and disassembly. The threaded design ensures a leak-proof seal, commonly used in various applications requiring regular maintenance or modifications.

PVC pipe fittings
Material Selection: uPVC and PVC
The fittings are made from uPVC (unplasticized polyvinyl chloride) and PVC (polyvinyl chloride), both of which are widely used for their excellent chemical resistance, durability, and ease of installation. These materials are perfect for water, gas, and other fluid systems, providing long-lasting and reliable performance even in challenging environments.
uPVC: uPVC fittings are commonly used in industrial and domestic plumbing systems. They offer high mechanical strength, resistance to corrosion, and are lightweight, making them easy to handle and install.
PVC: PVC is widely used for its versatility and cost-effectiveness. It is suitable for both indoor and outdoor use and is resistant to various chemicals, making it ideal for various plumbing and drainage systems.
