Prevent Your 13mm Pipe From Crimping
Sometimes you need to navigate the backbone of your tank series 13mm tube round some tight corners.
In order to keep your 13mm tube in good working order, and to keep your lines nice and even, it's a good idea to use a 13mm Elbow Connector.
This will keep your pipe open and free of any waterflow issues from crimped or creased pipes, and it will give you clean 90 degree angles so that your tubing can run as close to the edges of your beds as possible.
Installation is simple. Where you need to get around a corner, cut your 13mm pipe and install both cut ends onto the 13mm Elbow Connector.
