The forged 316 stainless steel union features precision-machined swivel nuts for easy alignment during installation, even in confined spaces. The tapered seat design ensures leak-proof connections without thread compounds, while the full-flow passage minimizes pressure drop. Three critical applications: 1) High-purity pharmaceutical fluid transfer systems requiring frequent disconnection for cleaning. 2) Brewery piping where sanitation and easy maintenance are paramount. 3) Offshore instrumentation lines exposed to seawater spray. The unions meet 3-A sanitary standards when ordered with electropolished finish and are available with optional safety wire holes for critical service.
