Additionally, cleanliness of the pipe ends is important for proper sealing. Some users reported missing parts, specifically gaskets, which affects the overall completeness of the product. The caps are well-made, but attention to detail regarding the threading and gasket provision is critical for optimal performance. Therefore, despite their quality Construction, potential buyers should be well-acquainted with NPT standards and prepared for additional sealing materials if necessary. ###
