UPVC Socket
A UPVC Socket is a straight coupling pipe fitting used to connect two lengths of UPVC pipe in a secure and leak-proof manner. Designed for solvent cement jointing, the UPVC socket ensures a rigid and permanent connection within piping systems. It is widely used in irrigation, chemical distribution, and industrial fluid handling applications due to its durability and chemical resistance. A UPVC socket is a pipe fitting made from unplasticized polyvinyl chloride (UPVC) that is used to join two UPVC pipes of the same diameter. It means using solvent cement welding to create a strong, permanent, and leak-proof connection in a piping system.
A UPVC (Unplasticized Polyvinyl Chloride) socket is a straight and hollow cylindrical fitting designed to join two pipes of the same diameter. Because it is made of UPVC, it is rigid, and its durability is resistant to chemical corrosion, making it the standard choice for cold water fluid systems, drainage, leaking, and irrigation.UPVC Sockets are specially designed for chemical or ambient temperature water fluids. It should not be used for hot water lines, as the material can soften and deform under high heat.
