Crafted for resilience in demanding environments, this coupler features a high-strength, UV-stabilized molded plastic body, making it particularly effective for underground duct applications. The design includes an airtight and watertight O-ring seal to ensure environmental protection, while its robust pull-out strength of 1,000 lbs and maximum pressure rating of 15 PSI offer peace of mind for secure connections. Ideal for seamlessly connecting HDPE sticks and reeled products, it also boasts user-friendly stainless steel band clamps that can be hand-tightened using a 5/16" nut driver, ensuring effortless installation. For those working with a mix of materials, it's worth noting that for coupling HDPE to PVC, the Shur-lock II coupler is recommended.
