SS Hydraulic Union fitting

About SS Hydraulic Union fitting

An SS (Stainless Steel) hydraulic union fitting connects pipes/hoses in fluid systems, allowing easy disconnection for maintenance, featuring corrosion resistance (SS 304/316), high-pressure sealing (often double-ferrule), and types like straight, elbow, or tee for directional changes, crucial for reliable leak-proof systems in harsh environments like marine, chemical, or oil & gas. Key Features & Description: Material: High-grade stainless steel (SS 304, 316, 316L) for superior corrosion resistance, strength, and high-temperature performance. Function: Joins two pipe/tube sections, creating a secure, leak-tight passage for hydraulic fluid, air, or gas. Design: Often uses a three-part design (male, female, nut) or precision-engineered double-ferrule system for vibration resistance and sealing. Types: Available as straight (inline), elbows (90°), tees (three-way), or cross fittings. Sealing: Achieves leak-proof seals using compression (ferrules) or specific thread types (NPSM cone/chamfer), eliminating need for sealants,. Applications: Ideal for high-pressure, demanding applications in instrumentation, chemical processing, marine, and heavy machinery hydraulics. Bulkhead Variant: A specific type (bulkhead union) passes through a panel, secured by locking nuts.
