John Guest polypropylene equal elbow, 90°
Polypropylene push-fit fitting for joining two tube sections of the same diameter at a 90° angle. It changes line direction without making a tight bend in the tube itself.
Material and available sizes
The equal elbows on this page are polypropylene. The range includes 1/4", 5/16", 3/8", 1/2", 10 mm and 15 mm, plus the 15 mm threaded variant shown in the selector.
When to use an equal elbow
Suitable for corners, cabinets, compact equipment and routes where bending the tube could cause restriction, stress or an unsuitable bend radius.
Installation
Cut both tubes square, confirm they match the selected variant and insert fully. Leave enough length to avoid pulling on the fitting.
Maintenance
Check that the tubes are not marked next to the collet and that the elbow is not supporting the weight of other components.
