Home > Adjustable Locknut Elbow
Paul Tube Fittings, based in Houston, USA, is a trusted name in manufacturing and supplying high-performance Adjustable Locknut Elbows. These fittings are crafted for precision and secure connections between tubes and ports in hydraulic and pneumatic systems. They offer the flexibility to adjust direction during installation, making alignment a breeze without sacrificing sealing integrity. Made from top-quality stainless steel and corrosion-resistant alloys, these elbows are perfect for heavy-duty industrial use. Paul Tube Fittings guarantees that each adjustable elbow adheres to strict dimensional and pressure standards, ensuring reliable, leak-proof performance. They’re commonly found in construction machinery, fluid power systems, and automation equipment, providing both versatility and long-lasting durability.
Adjustable Locknut Elbows are usually made from stainless steel grades like SS 304 or SS 316, which contain 18–20% chromium and 8–14% nickel (with 2–3% molybdenum in SS 316). These materials deliver impressive mechanical strength, boasting tensile strengths around 515 MPa and yield strengths of about 205 MPa. The stainless steel construction guarantees excellent corrosion resistance, high pressure tolerance, and outstanding fatigue life in dynamic systems. The locknut feature allows for secure orientation adjustments without needing to disassemble, making these elbows perfect for high-vibration and high-pressure environments where alignment and sealing reliability are key.
