Geometric design and performance of 90° compression elbows
The 90-degree compression elbow is used to negotiate perpendicular turns in polyethylene pipelines around obstacles, chamber entries, and field boundaries. The smooth internal sweep minimizes localized head loss and prevents vortex-induced wall wear. Both ports incorporate independent mechanical grips and O-rings, shielding lines from thrust forces and pressure surges caused by rapid valve actuation.
Complying with ISO 17885 standards, these elbows maintain exceptional pull-out resistance once tightened, resisting pipe dislodgement under hydrostatic pressure and thermal contraction. The UV-stabilized polypropylene body resists solar degradation and corrosive soil contact over extended field service.
Size range and installation best practices
Polypropylene 90° compression elbows are typically manufactured for pipe outside diameters between 20 and 125 mm, rated at PN10 nominal pressure. This span accommodates everything from 20 mm lateral drip sub-mains to 125 mm primary trunk lines.
For proper corner installation, pipe ends must be chamfered and inserted squarely into each socket without excessive angular strain. Tightening the cap nut with a suitable wrench ensures dependable hydraulic integrity. Please indicate your required diameters in our online request form for formal quotations.

Compression Elbow 90° — FAQ
What sizes are commonly manufactured for 90-degree compression elbows?
This fitting is typically supplied in outside diameters of 20, 25, 32, 40, 50, 63, 75, 90, 110, and 125 mm.
How does the polypropylene elbow tolerate freezing conditions?
Polypropylene exhibits elastic resilience, but line draining prior to deep winter freezes is strongly advised to prevent freeze rupture.
What angle of diversion is provided by this elbow?
This fitting is engineered specifically for a standard 90-degree perpendicular turn to redirect piping layouts.
Is this fitting suitable for drinking water distribution?
Yes, the virgin polypropylene formulation and inert elastomeric seals impart no taste, odor, or toxic leachates to drinking water.
