90 Degree Rubber Pipe Elbow

• One-piece flexible 90° elbow combines right-angle turning, displacement compensation and vibration damping in a single unit
• Seamless molded corner construction delivers consistent sealing without joint weaknesses at the bend point
• Lighter than equivalent rigid steel elbows, no heavy lifting equipment required for installation
• Reduces turbulence noise and absorbs equipment vibration at pipeline right-angle turning points

This rubber elbow replaces rigid metal elbows at right-angle turns in building water supply and HVAC systems, adding vibration isolation and minor displacement compensation to reduce stress on pipe welds. It also mounts at pump, fan and heat exchanger inlet/outlet turns, cushioning equipment vibration and compensating minor installation misalignment.

Henan Fuwei Pipeline Equipment Manufacturing Co., Ltd. offers custom bend angles such as 45° and 60° besides the standard 90° configuration. End connections are configurable as flanged, threaded or spigot to match existing piping layouts, and rubber material can be adjusted for oil, weather or corrosion resistance per medium requirements. Custom sample lead time is 15–20 days with an MOQ of 10 units.

Corner seal integrity is verified through angle-specific hydrostatic testing. Bending fatigue testing validates service life under repeated displacement cycles. Pressure resistance and rubber hardness are tested per production batch. Every unit completes 100% inspection before dispatch, third-party inspection is accepted, and a 24-month warranty applies.

Corner sections are fitted with dedicated protective guards to prevent crushing deformation in transit. End caps cover connection ends to avoid thread or flange face damage. Small units ship in cartons; large sizes use custom crates with internal bracing. Standard 20ft container orders ship within 30 days; custom angle units have a 40–50 day lead time.

• 90° is standard; 45°, 60° and other custom angles are available on request
• Flanged end connections are available for direct mating with standard flange pipelines
• NBR rubber compound is available for oil and lubricant medium applications
