Stainless Steel Double Press-Fit Fittings 45-Degree Elbow A-Type

Category Tag

  • Optimized Directional Change: Engineered for smooth 45° turns, reducing flow resistance and pressure drop in piping systems compared to sharper angles.

  • Dual Press-Fit Ends (Type A): Both connection ports are identical and designed for permanent press-fit installation, creating a complete, standalone fitting for gradual turns.

  • Reliable Dual-Seal Design: Each end features a precision O-ring seal, activated by the calibrated double-press process to ensure two independent, leak-proof connections.

  • Ideal for Efficient Layouts: Perfect for long pipe runs, navigating around obstacles with minimal space penalty, and creating offset connections in mechanical rooms.

  • Certified Quality: Manufactured from corrosion-resistant 304/316L stainless steel, compliant with GB/T 19228, ISO 15835, and individually hydrostatic tested.

Engineer Smoother Flow with a Gradual 45° Turn

The Stainless Steel Double Press-Fit 45° Elbow (Type A) is the optimal solution for piping layouts that demand efficiency and minimal flow disturbance. As a key component in our Double Press-Fit System Overview, this fitting enables a gentler, 45-degree directional change, effectively reducing turbulence and long-term energy loss in system pumps—a critical consideration in large commercial projects.

 

Strategic Advantage: The 45-Degree Angle for Performance

While 90° elbows are standard for right-angle turns, the 45° elbow serves distinct and valuable purposes:

  • Reduced Flow Resistance: Offers a hydraulically superior alternative to 90° elbows, minimizing pressure loss, especially in high-flow or long-distance runs.

  • Space-Efficient Routing: Allows for more gradual and often more compact routing around structural elements or other MEP services.

  • Creating Precise Offsets: Two 45° elbows can be used in sequence to create a parallel offset in a pipeline, a common requirement for alignment.

 

Type A Design: For Complete, Permanent Connections

This “Type A” variant is defined by its two press-fit ends, designed for situations where a complete and permanent 45° turn is needed between two pipe sections. This symmetrical design ensures:

  • Installation Simplicity: No need to differentiate between ends, speeding up the installation process.

  • Uniform Reliability: Both seals benefit from the same rigorous System Pressure & Performance Testing protocol (>1.05 MPa individual test, 2.5 MPa system test), guaranteeing the integrity of the entire fitting.

Engineered with Premium Materials and Rigorous Standards

  • Material Integrity: Available in grades 304, 304L, 316, and 316L stainless steel, selected for their durability and corrosion resistance in various water qualities.

  • Global Compliance: Manufactured to meet and exceed GB/T 19228.1-2011, ISO 15835, and EN 10312, ensuring suitability for domestic and international specifications.

  • Verified Performance: Every fitting is subject to stringent quality checks, including eddy current testing and flattening tests, ensuring material properties like tensile strength (≥520 MPa) are consistently achieved.
