Purple pipe fittings: Donsen new purple series pipe fittings are made of environmentally friendly Korean imported Hyosung material, and the copper parts are made of EU standard CW617N copper.
Advantages: 1. In addition to maintaining the original dovetail structure, the copper structure also adds waterproof grooves at different positions to ensure sealing performance and prevent leakage! 
2. The wall thickness of the copper parts is thickened, the strength is improved, and the service life of the products is improved;
3. The length of the copper piece is lengthened, which avoids the defect that the plastic part is easy to produce the air hole, enhances the product toughness and improves the service life of the product.
