The 2" Redi-Lock HDPE Couplings by Duraline are designed for robust connections in various pipe and conduit applications, especially when working with HDPE materials. Featuring a high-strength molded plastic body, these couplings ensure durability and dependability in demanding environments. Each coupling provides an airtight and watertight seal thanks to its effective O-ring, and is equipped with stainless steel band clamps featuring a self-locking ring for secure installation. To optimize performance, these couplings are recommended for connecting HDPE sticks and continuous length products, with a maximum pressure rating of 70 PSI and a pull-out strength of 700 lbs. It’s important to note that these couplings are not suitable for use with PVC, and for those applications, the Shur-lock II coupler should be used instead. Perfect for a variety of projects, a carton contains 10 couplings, making them a practical choice for contractors and DIY enthusiasts alike.
