Straight Thread Reducers and Expanders are essential components in fluid and gas handling systems, designed to connect two fittings or components of different thread sizes while maintaining a straight-threaded seal. Whether you’re downsizing or upsizing a port, these compact fittings ensure a secure, leak-free connection without the need for complex reworking or system redesign.
Manufactured from high-performance materials like Stainless Steel, Brass, Carbon Steel, and Alloy Grades, these reducers and expanders offer exceptional pressure and temperature resistance, making them ideal for harsh industrial environments. Their precision-machined threads ensure compatibility with NPT, BSPP, or other thread standards, streamlining installations across hydraulic, pneumatic, chemical, and instrumentation systems.
Whether you’re reducing a 1/2″ port to 1/4″, or expanding a 3/8″ fitting to 1/2″, these fittings offer adaptability with integrity—perfect for system retrofits, upgrades, or space-restricted designs. Available in a wide range of thread combinations and sizes, they help maintain system performance while enhancing flexibility.
