This adapter is definitely not a professional adapter: - NPT thread quality is not perfect, - Fit thickness is not enough compared to pro-grade -Adaptors, - the fitting is extremely short (only 4 fittings) compared to pro grade adapters (7,9,11 spikes). This means there is no room to install two or three clamps for applications similar to installing a deep water pump. See attached picture. According to the product description, this adapter "contains lead and is not federally legal for use in drinking water in the United States and its territories". However, it costs as much as some lead-free adapters.
