Hebei Ruijie Pipe Industry Co., Ltd. is one of the most reliable manufacturers and suppliers of green ppr pipe fittings in China. With abundant experience, we warmly welcome you to buy high quality green ppr pipe fittings for sale here from our factory. Also, pricelist and free sample are available.
Green PPR pipe fittings are connecting components for hot and cold water supply systems, manufactured by integral injection molding from food-grade random copolymer polypropylene (PP-R), with the industry-standard green identification color. Through hot-melt welding, they achieve molecular-level fusion with pipes of the same material, enabling pipe direction changes, flow splitting, butt joining, diameter transition, and transition connections to metal equipment.
Product Advantages
Hot-melt integral sealing
Joint strength is no lower than that of the pipe itself, eliminating the leakage risks of threaded and clamp connections, with stable sealing under repeated thermal cycling.
Food-grade material
Produced from 100% virgin material, odorless and with no harmful substance leaching, compliant with drinking water hygiene requirements and suitable for direct use in potable water lines.
Temperature and pressure resistance
Stable creep resistance under long-term 70°C hot water conditions, with a designed service life of up to 50 years.
Full range of types
Full diameter and category coverage; smooth interior resists scaling; best fusion with same-brand products, also compatible with national-standard pipes.
Product Details
Anti-pullout brass insert
Multiple annular undercut grooves on the outside of the brass insert bite tightly into the plastic body, preventing loosening or dislodgement under prolonged tightening and thermal cycling.
Uniform wall thickness
Injection molded with high-precision molds, with minimal wall thickness deviation and even heating during hot-melt, avoiding cold welding and over-melting.
Streamlined flow channel
Internally rounded transitions reduce vortex and resistance, lower water flow noise, and prevent diameter reduction.
Clear markings
Each piece is surface-molded with its specifications, pressure rating, and brand logo, with wear-resistant markings for easy maintenance verification.
FAQ
Q: Can it be used to transport hot water?
A: Yes. It withstands long-term temperatures of 70°C and short-term peaks of 95°C, suitable for both hot and cold water supply systems in homes and buildings, as well as low-temperature heating lines.
Q: Can different brands be hot-melted together?
A: In theory, any PPR material pipe and fitting that meets national standards can be hot-melted together. However, we recommend prioritizing same-brand matching products, as identical material formulations provide the best fusion compatibility and sealing reliability.
Q: Will the brass insert rust?
A: No. High-quality brass is inherently corrosion-resistant, and the main body is encased within the plastic, avoiding large-area contact with water.
Q: Can damaged fittings be repaired?
A: If the fitting body is cracked, it is recommended to replace it directly with one of the same specification; if the joint has a welding defect, the defective section can be cut out and reconnected using a coupling or union fitting, without replacing the entire line.
Storage Guidelines
Store in a ventilated, dry warehouse away from fire and heat sources, avoiding direct sunlight; ambient temperature -5°C~40°C, not to be stored together with sharp, high-temperature, or corrosive items; stack by specification and category at moderate height, storing threaded-insert fittings separately to prevent impact damage; handle with care, no throwing or dragging; under proper storage conditions, storage period should not exceed 2 years, and products beyond this period must be re-inspected before use.
