Coupling Ppr Pipe Fittings
This coupling fitting is made from Polypropylene Random Copolymer (PPR) Type III, designed for hot and cold water distribution systems with a working pressure rating of up to 10 bar at 20°C. The fittings are manufactured using precision injection molding to ensure dimensional accuracy and consistent wall thickness across DN20mm to DN110mm sizes. Each joint is intended for heat fusion welding, creating leak-free, monolithic connections that meet international plumbing standards such as ISO 15874.
The material is non-toxic, corrosion-resistant, and offers low thermal conductivity, making it suitable for both residential and commercial installations. Standard colors include white, green, and grey, with custom options available. The fittings are free from heavy metals and comply with food-grade safety requirements for potable water. Unlike some lower-grade PPR products, these are produced with consistent polymer melt flow and minimal internal roughness to reduce scaling and flow restriction over time.
These fittings are primarily purchased by plumbing contractors, water system installers, and building material distributors across Southeast Asia, the Middle East, and Eastern Europe. Packaging is in plastic bags with carton outer cases, with custom packaging available. Lead times are 5 days for orders under 500 pieces, 15 days for 501 - 1000 pieces, and negotiable above 1000. The product has a projected service life exceeding 50 years under normal operating conditions.

Sourcing Coupling Ppr Pipe Fittings from Liaoning Jianxi Science And Technology Co., Ltd - China Import Guide
Before placing an order, verify the material grade with a certificate of analysis showing MFR and density values for PPR Type III. Request physical samples to inspect wall thickness uniformity and internal smoothness using a caliper and magnifying lens. Confirm the colorants are non-toxic and comply with drinking water standards. Do not accept products without documented compliance with ISO 15874 or equivalent standards.
Lead time is 5 - 15 days depending on order volume, with larger quantities negotiable. Confirm Incoterms - most likely FOB Shenyang or CIF port of destination. Payment terms are typically 30% advance, 70% against copy of bill of lading. Packaging is standard in cartons, but custom labeling and palletization may require additional lead time. Always request a packing list matching the shipment contents.
Upon arrival, conduct a visual inspection for surface cracks, warping, or discoloration. Measure the outer diameter and wall thickness of at least three random fittings against the supplier’s stated specs. Perform a simple fusion test on a sample to confirm weldability and joint integrity. Retain a sample batch for third-party lab testing if the system is for critical infrastructure. Request a quality control report with batch numbers before final payment.
