PVDF Stub Flange
The PVDF Stub Flange is a specialized pipe fitting used in conjunction with a backing ring to create a secure and leak-proof flanged connection in a PVDF piping system. Made from Polyvinylidene Fluoride (PVDF), this component is designed for applications that demand exceptional chemical resistance, high purity, and long-term durability. PVDF stub flanges are ideal for corrosive fluid systems and ultrapure applications across industries such as chemical processing, pharmaceuticals, semiconductors, and water treatment.
