Silicone elbow reducer 90 deg 19 to 42 mm length 100 mm REDOX

Technical construction

The REDOX RDX19-42C90L100 elbow reducer combines a diameter transition (from 19 mm to 42 mm) and a 90 deg bend in a single part. The wall is a composite of 4 crossed polyester plies embedded in a premium VMQ silicone matrix, ensuring dimensional stability under heat and resisting pressure-induced creep. Internal bend radius is set at 1.5 times the larger of the two diameters to maintain flow rate and prevent stream necking. Wide thermal range -60/+180 deg C, peaks to +210 deg C, 5 bar working pressure (burst above 15 bar at 23 deg C). Matte outer finish, smooth inner surface to reduce flow losses.

Applications

Designed for angular diameter transitions on turbocharger lines, intercooler piping, engine cooling, water return loops, intake and boost circuits. Essential whenever the diameter change must occur together with a direction change, removing the need for a straight reducer plus separate elbow. Compatible with gasoline, diesel, E85, methanol and glycol coolant.

Benefits vs straight reducer + elbow

One-piece solution: fewer joints means fewer leak paths, shorter overall length, faster installation, compact footprint in busy engine bays. Continuous polyester reinforcement between the reduction zone and the bent zone removes the weak interface that two glued parts would create.
