his product is a 19mm elbow connector designed to facilitate a 90-degree turn in your piping without causing kinks or damage. It is ideally suited for use with 3/4" flexible corrugated reinforced pond pipe, commonly employed in setting up filters, pumps, waterfalls, and other water features. Included with this fitting are two double wire hose clips, which are specifically designed for this type of pipe. Unlike standard jubilee clips, these double wire clips fit snugly between the pipe's ridges, tightening without crushing the pipe. If the connector feels tight, you can gently warm the pipe with hot water to soften it for easier fitting. Made from tough, durable polypropylene, this fitting is resistant to degradation from sunlight.
