Swagelok SS-6UW-TJ6-4C-41544-NSR Bellows-Valve

Swagelok SS-6UW-TJ6-4C-41544-NSR Bellows-Valve is a stainless steel bellows-sealed valve from Swagelok’s U Series, engineered for leak-tight switching in high-purity and vacuum-sensitive process lines where containment and reliability are critical. With a 3/8 in nominal size, the valve employs a welded body-to-bellows seal (the W designation) and, in line with Swagelok’s U Series, provides secondary containment that prevents leaks to atmosphere even if the primary seal fails, a key safety feature for handling aggressive fluids and maintaining clean-room conditions. The unit uses a 316 stainless steel body, offering robust corrosion resistance, and is rated for working pressures up to 2500 psig (172 bar) with a temperature range from -20 to 650°F (-28 to 343°C), making it suitable for high-temperature, high-pressure switching tasks in instrumentation, analytical, and process applications. End connections are Swagelok tube fittings designed for compatibility with standard Swagelok tubing, and the 41544-NSR suffix denotes the exact model variant within the SS-6UW family, ensuring precise integration into existing Swagelok systems where durability and containment performance matter.
