90 Degree Elbow
Long Spigot Fittings
When your pipeline design requires sharp, precise directional changes within tight spatial constraints, the PE100 90 Degree Elbow is the industry-standard solution. Engineered to handle high-pressure water, gas, and industrial fluid transport, our premium poly elbows offer maximum structural integrity where your system needs it most.
When to use an injection-moulded 90 Degree Elbow?
An injection-moulded 90 Degree Elbow is the ideal choice for pipeline configurations where space is limited and a sweeping radius bend cannot fit—such as in urban utility trenches, treatment plant manifolds, and pump skids.
Because they are fully injection-moulded rather than segment-welded (fabricated), these elbows retain their full pressure rating throughout the fitting, eliminating the need to apply safety de-rating factors in your pipeline design.
The Advantage of Injection Moulding & Long Spigots
-
Zero De-rating Factors: Fabricated or "mitred" bends feature welded seams that reduce the maximum pressure capacity of the fitting. Our 90-degree elbows are single-piece injection-moulded components, ensuring uniform wall thickness and uncompromised strength.
-
Elongated Spigots (Long Tails): The extended straight sections provide installation crews with maximum on-site flexibility. They provide ample clearance for easy clamping in Butt Welding machines or the seamless attachment of Electrofusion Couplers.
Common Applications
The 90-degree poly elbow is universally relied upon for:
-
Perimeter Ring Mains: Constructing right-angle turns around buildings or mining infrastructure.
-
Manifold Assemblies: Fitting complex multi-valve networks into compact pump houses.
-
Vertical Riser Transitions: Connecting horizontal underground mains to above-ground vertical pipe drops.
