NINGXING PPR Brass Male Thread Union is a professional pipe fitting designed for connecting PPR piping systems with valves, faucets, water heaters, sanitary equipment, and other threaded components. It combines the excellent sealing performance of PPR heat fusion technology with the flexibility of brass threaded connections, providing an efficient solution for modern plumbing installations.
Manufactured with premium PPR materials and high-quality brass inserts, this PPR brass male thread union delivers reliable pressure resistance, corrosion resistance, and long-term durability. The detachable threaded structure allows easier maintenance and replacement compared with traditional fixed PPR connections, reducing repair time and installation costs.
With advanced production technology, strict quality control, and years of manufacturing experience, NINGXING provides high-performance PPR connection solutions for residential buildings, commercial projects, heating systems, and international plumbing markets.
Product Overview and Key Advantages
1. Flexible Connection Design for Modern Plumbing Systems
Traditional PPR pipe connections mainly rely on heat fusion, creating permanent joints that cannot be easily removed after installation. When valves, water heaters, or sanitary equipment require replacement, workers often need to cut pipes and perform additional repairs.
NINGXING PPR Brass Male Thread Union solves this problem through a combination of permanent PPR fusion connection and detachable brass thread connection. The PPR side creates a strong integrated seal with the pipeline, while the brass male thread allows convenient connection and removal of external equipment.
This design improves system flexibility and is especially suitable for connection points requiring future maintenance.
2. Suitable for Residential and Engineering Applications
The product is widely used in household water supply systems, bathroom plumbing, kitchen pipelines, heating systems, commercial buildings, and engineering construction projects.
For contractors and installers, the detachable structure helps simplify installation and future maintenance. Equipment replacement can be completed without damaging the original pipeline system, reducing labor costs and improving project efficiency.
Material and Manufacturing Advantages
1. High-Quality Brass Insert for Reliable Thread Performance
The brass insert is manufactured from premium brass material with excellent mechanical strength and corrosion resistance.
The precision-machined male thread provides smooth installation and stable connection performance, reducing problems such as thread slipping, deformation, or leakage caused by poor processing accuracy.
For applications requiring frequent maintenance, the durable brass structure ensures reliable performance during repeated connection and removal.
2. Premium PPR Material for Long Service Life
The PPR body uses high-quality raw materials with excellent heat resistance, chemical stability, and pressure performance.
Compared with traditional metal piping materials, PPR has lower thermal conductivity, which helps reduce heat loss in hot water applications. Under normal operating conditions, the complete piping system can achieve a service life of more than 50 years.
The smooth inner wall design reduces water resistance and helps prevent scale accumulation, ensuring stable water flow performance.
3. Integrated Manufacturing Technology
NINGXING adopts advanced injection molding and brass insert embedding technology to ensure strong bonding between the PPR body and brass components.
Unlike simple assembled fittings, the integrated structure improves overall reliability and reduces the risk of separation caused by temperature changes, pressure fluctuations, or long-term operation.

Installation Guide for PPR Brass Male Thread Union
1. Preparation Before Installation
Before installation, confirm that the fitting size matches the PPR pipe specification. The pipe surface should be clean and free from dust, oil, or moisture.
Prepare professional heat fusion equipment and suitable sealing materials for the threaded connection section.
2. PPR Heat Fusion Installation
First, cut the PPR pipe vertically and ensure the pipe end is smooth.
Heat the pipe and fitting socket using a professional fusion machine according to standard heating requirements. After reaching the correct temperature, insert the pipe into the fitting evenly and allow the joint to cool naturally.
A properly completed heat fusion connection creates a permanent and leak-resistant joint.
3. Brass Thread Connection
After the PPR side has cooled, wrap sealing material around the brass male thread and connect it with valves, hoses, or other threaded components.
During tightening, apply suitable force to avoid damaging the brass thread. After installation, perform a pressure test to confirm system reliability.
Real Application Cases
1. Residential Balcony Water Line Renovation
A home renovation project used NINGXING PPR Brass Male Thread Union for installing a washing machine water connection on a balcony.
The installer completed the DN20 connection within approximately 15 minutes. Compared with traditional fixed welding methods, the detachable structure simplified future maintenance.
After 18 months of use, the connection remained stable with no leakage or loosening issues.
2. Water Heater Maintenance Application
A residential project installed the product at water heater inlet and outlet connections.
During later maintenance, technicians were able to disconnect the equipment directly from the union connection without cutting the PPR pipeline.
The maintenance process time was reduced by approximately 40%, avoiding wall damage and reducing repair costs.
3. Commercial Plumbing System Project
A commercial building project selected DN25 and DN32 models for multiple bathroom water supply points.
The contractor reported that the flexible connection design improved installation efficiency by around 25% compared with conventional fixed connection solutions.
After one year of operation, the pipeline system maintained stable pressure performance without leakage problems.
