Copper Fitting Cap

The Copper Fitting Cap is essentially a high-performance sealing component for copper tube ends. Manufactured from T2Y2 (half-hard) grade copper-featuring a copper content exceeding 99.9%-it offers an optimal combination of thermal conductivity, ductility, and mechanical strength. The product features a classic reddish-copper hue, a smooth oxide-free surface, and a uniform inner wall, ensuring a perfect fit with the copper tubing. Compared to standard brass or stainless steel fittings, the T2Y2 copper cap offers a coefficient of thermal expansion that closely matches the piping itself, thereby eliminating the risk of joint loosening or leakage caused by temperature fluctuations.
Key features include:

Precision Dimensional Fit: Strictly adheres to international standards (such as ASME B16.22); the socket design is precision-engineered to accommodate various copper tube outer diameters, ensuring a gap-free seal.
Half-Hard Characteristics: The Y2 temper provides a balance of hardness and workability, facilitating on-site installation and welding while ensuring resistance to deformation under pressure.
Optimized Surface Treatment: Produced using a precision degreasing process and nitrogen-purged packaging to prevent oxidation during transit, ensuring high system cleanliness post-installation-making it particularly suitable for refrigeration and medical applications.
