Size Specifications: Covering All Sizes from 1/4 Inch to 2 Inch Straight-through copper bushings come in sizes similar to clothing sizes, ranging from 1/4 inch (approximately 6.35mm) to 2 inches (approximately 50.8mm). For common household applications, 1/2 inch (15mm) or 3/4 inch (20mm) sizes are sufficient. Industrial piping may require 1 inch (25mm) or even larger. When choosing a size, remember: match the outer diameter to the pipe, and the inner diameter to the flow rate-for example, a 1-inch bushing has an inner diameter of approximately 25mm and can handle 6-8 tons of water per hour (depending on pressure).
Material Characteristics: The Comparison of H62 and H65 Brass Copper bushings primarily use two types of brass: H62 (62% copper) and H65 (65% copper). H62 is harder and suitable for high-pressure environments; H65 is softer and easier to machine into precision threads. H62 is sufficient for household use, while H65 is recommended for industrial applications-for example, in air conditioning refrigerant pipes, H65 bushings offer better resistance to refrigerant corrosion. Here's a little secret: Good connectors have a nickel-plated surface, making them smooth like stainless steel and preventing oxidation for over 3 years.
Suitable for: Water/Gas/Oil - Universal Design. Don't think copper connectors are only for water pipes! High-quality straight-through copper sleeve connectors can handle water, gas, and oil simultaneously. When connecting water pipes: Use the standard type for cold water, and choose one with a PTFE sealing ring for hot water (capable of withstanding 120℃). For gas pipes, choose one with a smooth inner wall to reduce airflow resistance; for oil pipes, choose a galvanized type to prevent oil corrosion. Tip: Before installation, wrap 3-5 turns of Teflon tape around the threads; the sealing effect is 3 times better than simply tightening!
