Donaldson P105531 90 Degree Rubber Elbow

Application & Fit

The Donaldson P105531 is a transparent 90-degree rubber elbow designed for automotive interior care and fluid routing. It serves mechanics and DIY owners who need a clean, right-angle connection in tight engine-bay or cabin spaces. The neutral colour lets you inspect flow visually without removing the part. Buyers needing a straight coupler or a different bend angle cannot use this elbow.

Installation Notes

The elbow pushes onto compatible hose ends and is held by standard clamps; no tools beyond a screwdriver or socket are required. Because the rubber stays flexible, it absorbs vibration and minor misalignment without kinking. Problems usually arise when the hose inner diameter does not match the elbow bore, causing leaks or the elbow to pop off under pressure. Always verify the hose size before fitting.

Capacity & Limits

The 90-degree bend handles typical coolant, vacuum or low-pressure fluid lines found in passenger-vehicle interiors. Its transparent wall lets you spot blockages or air pockets during routine checks. The rubber compound resists normal under-bonnet temperatures but is not rated for high-pressure fuel or hydraulic systems. Runs requiring sustained pressure above the material rating will need a reinforced alternative.
