Home > Swivel Union
A Swivel Union is a unique fitting for pipes or tubes that allows for rotation between connected parts while ensuring a tight, leak-proof seal. This feature makes installation and alignment in piping, hydraulic, and instrumentation systems much easier, helping to reduce stress on the pipes and preventing leaks that can happen due to misalignment. Typically, Swivel Unions are made from materials like stainless steel, carbon steel, Monel, or nickel alloys, which offer great resistance to corrosion, along with mechanical strength and durability in tough industrial settings. You’ll find them commonly used in fields like chemical processing, petrochemicals, oil and gas, power generation, and marine applications.
These fittings boast impressive mechanical properties, such as high tensile strength, toughness, and stability even under pressure and temperature changes. With precision-machined sealing surfaces and threads, they ensure reliable leak-proof performance, and the swivel mechanism allows for rotation without compromising the connection’s integrity. Their sturdy design can withstand vibration, stress, and wear, making them a dependable choice for critical piping and instrumentation systems.
