Stainless Steel Union (M/F) — 3-Piece Threaded Fitting
Stainless Steel Union (M/F)

Stainless Steel Union (M/F)

Our stainless steel unions (Male/Female) are high-integrity three-piece fittings designed to connect threaded pipes securely while allowing for easy maintenance. The M/F design enables direct connection between a female-threaded pipe and a male-threaded component, providing a tight, leak-proof seal that can be disassembled without cutting the pipeline.
