This is a generic S141 nozzle, identified by its part number S141. Due to its unbranded designation, specific technical specifications, fitment details, and cross-references cannot be verified from authoritative OEM or trusted distributor sources. Information for branded S141 nozzles (e.g., TeeJet S141 series) typically describes a wide-angle flat spray pattern nozzle designed for uniform coverage and spraying around obstacles, often made from materials like brass or stainless steel. However, these details cannot be attributed to an unbranded version without explicit verification.
