This heavy-duty mechanical joint retainer gland ring is crafted from durable ductile iron and designed to provide secure, high-strength restraint for pressurized piping systems. Marked with part number 11-03SA1 and accompanied by a partial Underwriters Laboratories (UL) tag indicating pressure ratings up to approximately 350 PSI, it is well-suited for demanding municipal water, wastewater, and industrial applications. The ring features evenly spaced bolt lugs and pre-drilled holes to ensure uniform clamping and reliable joint integrity under load. Built to withstand harsh environments, it shows typical cosmetic wear from prior use but remains a solid, functional component ideal for maintenance, repair, or replacement in pipeline infrastructure.
