This item serves as a water butt, rain barrel, or tank outlet elbow compatible with hoses with a 1" or 25mm interior diameter. To install it, you will need a 26mm hole, with the nut and washer placed inside. It features a 25mm barb, designed for a snug fit to prevent the hose from slipping off. If fitting the hose is challenging, soften the hose end by immersing it in hot water to stretch it. Attach the connector, and as the hose cools, it will contract around the connector, creating a watertight seal. Made from durable polypropylene with built-in UV resistance, this item is less prone to cracking, chipping, or discoloration. The elbow can be adjusted to any angle to suit your needs.
