Offered for sale is a LOKRING MAS-3000-CPL-P48 industrial mechanical pipe coupling, manufacturer part number 9041804. This heavy-duty 3-inch nominal pipe fitting is manufactured from microalloyed carbon steel and belongs to LOKRING’s patented Elastic Strain Preload (ESP) pipe connection system, also known as LOKRING-Coldweld technology. Designed for permanent mechanical joining of compatible carbon steel piping, this coupling uses a specialised swaging mechanism to create a strong 360-degree metal-to-metal sealing connection without conventional welding. It is engineered for demanding industrial piping installations, including process piping, marine and offshore applications, and other compatible pressure-piping systems. The manufacturer specifies a 3-inch nominal pipe size, 3.54-inch fitting bore, 9.43-inch uninstalled length and 6.69-inch installed length, with an approximate manufacturer-listed weight of 4.14 kg (9.13 lb). Installation requires compatible LOKRING hydraulic installation tooling. This is a pre-owned industrial component showing signs of previous use, including surface scratches, handling marks and cosmetic wear. Please examine all photographs carefully to assess the actual condition. The item is supplied exactly as pictured, with no additional installation equipment included unless shown. An excellent replacement or spare component for industrial maintenance, piping projects and compatible LOKRING systems. Please verify the part number, pipe specifications, dimensions and application requirements before purchasing.
