## Long description

REHAU Kolano 20x1.9/90° SDR11 RAUPEX is a 90-degree pipe elbow engineered for RAUPEX cross-linked polyethylene piping systems. With a nominal outer diameter of 20 mm and a wall thickness corresponding to SDR11 (approximately 1.9 mm), the fitting provides a compact and reliable directional change for potable water and underfloor heating circuits. The elbow is intended for use with matching RAUPEX piping and compatible press or compression connections to maintain system integrity and long-term performance.
