Description
SRLU Series Reducing Long Union fittings (U-Union Reducing Side Extend) are precision-engineered for high-purity and high-pressure tube systems. Featuring a reducing design with an extended body, these fittings enable seamless connections between different tube sizes, ensuring secure and efficient gas or fluid flow.
With working pressures up to 3700 psi and broad compatibility with tube sizes from 3/8" to 1", SRLU fittings are ideal for semiconductor gas delivery, lab piping systems, and ultra-high-purity (UHP) environments. Manufactured from high-quality stainless steel and adhering to rigorous quality standards, these fittings deliver superior corrosion resistance, mechanical strength, and long-lasting durability.
