Copper coupling Fitting
Product Description
This 3/4 in. pressure slip coupling is ideal for air conditioning and refrigeration and potable water applications. Constructed with top-quality copper, this coupling connects or repairs two lengths of tube and is commonly used aboveground for water supply piping. It features a solder cup and is furnished without a center stop. Its dezincification-resistant design protects the adaptor’s mechanical strength.
