Pipe and piping fittings
90-degree elbow
Changing line direction with a defined angle and radius
Specialist selection guide
What should be reviewed before selecting this product?
A threaded 90-degree elbow changes direction in utility and small-bore lines. Thread standard and hand, material, coating, sealant and pressure-temperature limits must suit the complete system.

Common technical questions
Concise answers before enquiry
Does a taper thread seal by itself?
In practice, fluid, thread tolerance and project procedure determine the compatible sealing compound required.
Can different thread standards be connected?
No. Visual similarity does not ensure matching angle, pitch and diameter, and forced assembly can leak or fail.
