Description
Overview:
This genuine Loncin O‐Ring is a circular black rubber seal sized 160 mm diameter by 4 mm thickness (6.3 in by 0.16 in). It restores a tight, dependable seal in 1 inch (25.4 mm) Loncin water pumps, helping to prevent leaks and maintain stable suction and discharge pressure. Built for routine servicing and repairs, it fits Loncin LC25ZB21 and LC25ZB21-1.2Q pumps and is made from durable rubber suitable for continuous water contact. The precise profile allows the ring to sit evenly in its groove, reducing the chance of bypass and pressure loss. Supplied to Loncin's OEM specification, it is a straightforward replacement for worn or flattened seals and supports reliable operation in both trade and DIY settings.
