## Long description

Elbow 90° welded Modern PE-RT PE polyethylene 16x16 (sleeve) SiGMA-Li PERTK9016T is a compact welded 90-degree elbow designed for PE-RT and PE pipe systems. Intended for directional changes in hot and cold water distribution and underfloor heating manifolds, the fitting joins two 16 mm polyethylene pipes using a sleeve-style welded connection. Its restrained profile minimizes space requirements while providing a smooth internal flow path suitable for residential and light commercial plumbing installations.
Advantages
The welded sleeve connection provides a permanent, leak-resistant joint when fused correctly, reducing the need for mechanical couplings. Compatibility with PE-RT pipe materials ensures thermal stability for hot water applications and resistance to typical plumbing chemicals. The compact 90° geometry is designed to fit tight installation spaces and to maintain good hydraulic performance. Manufactured to typical industry dimensions for 16 mm systems, the fitting offers predictable installation and interchangeability with standard polyethylene tubing.
Suitable for
 Directional changes in hot and cold water distribution networks
 Underfloor heating circuits and manifolds
 Residential plumbing and light commercial installations
 Concealed pipe runs where a compact elbow is required
Key specifications
 Material: polyethylene suitable for PE-RT applications
 Connection type: welded sleeve joint for fusion welding
 Angle: 90 degrees
 Nominal size: 16 mm × 16 mm
