Shanxi Kaisheng Plastic Co., Ltd. is one of the most reliable manufacturers and suppliers of tee fittings in China. Please feel free to buy CE approved tee fittings in stock here from our factory. All customized products are with high quality and competitive price. Contact us for quotation.
Product Overview
Tee Fittings are used to create branch connections in hot and cold water piping systems. The range includes equal tees for same-size pipe connections and reducing tees for connecting different pipe diameters.
Manufactured from PP-R material and designed for socket fusion connection, the fittings can be supplied in different sizes, pressure classes and configurations to match the selected PP-R piping system.

Material & Engineering Performance
Material Options
PP-R Type 3 / PP-R 80: Optimized for general residential and commercial hot/cold water piping, offering balanced pressure resistance, high chemical stability, and long-term service performance (50+ years design life under standard conditions).
PP-RCT (Random Crystallinity Temperature): Engineered for higher-temperature and higher-pressure applications, featuring an improved crystalline structure and superior stress resistance compared to conventional PP-R.
Key Engineering Data
Pressure Ratings: PN16, PN20, and PN25 options matched to appropriate SDR ratings (SDR 11, SDR 7.4, SDR 6).
Internal Surface: Mirror-smooth inner bore minimizes flow resistance, prevents scaling, and minimizes head loss.
Thermal Expansion: Low thermal expansion coefficient of approximately 0.15 mm/m·°C.
Welding Compatibility: Uniform socket fusion fusion-zone design ensures reliable, homogenous joints with any standard global socket fusion machine.
Product Types & System Integration
Equal Tee: Features identical branch and run diameters, ensuring a consistent flow volume, velocity, and pressure distribution across both main and secondary lines.
Reducing Tee: Incorporates a smaller branch diameter to efficiently step down pipe dimensions, significantly reducing installation time and eliminating the need for extra adapter bushings.
Seamless System Integration: Engineered to exact dimensional tolerances, ensuring flawless compatibility with standard PP-R straight pipes, elbows, ball valves, and bridging bends used in modern building infrastructure.
Application Scenarios & Engineering Selection
Residential & Commercial High-Rise Buildings
System Focus: Domestic hot and cold water distribution.
Recommended Spec: PN20 series / Equal & Reducing Tees / Standard PP-R Type 3.
Engineering Note: Designed for lower noise transmission, effective pressure-spike absorption, and long-term service stability.
Industrial Process Water Networks
System Focus: Moderate chemical fluid transport and HVAC cooling loops.
Recommended Spec: PN25 series / PP-RCT material.
Engineering Note: Enhanced crystalline structure minimizes material creep under continuous operational stress and elevated temperatures.
Subterranean & Outdoor Exposed Runs
System Focus: Direct underground burial or rooftop overhead installations.
Recommended Spec: UV-stabilized variants or insulated jacket configurations.
Engineering Note: Prevents environmental degradation and material embrittlement during outdoor exposure.
OEM & Bulk Supply
Flexible Customization Options
Product Specifications: Size combinations, equal or reducing tee configurations, and pressure classes.
Aesthetics & Branding: Custom product colors, laser-printed customer logos, and unique product markings.
Packaging & Logistics: Tailored inner packaging, custom carton labeling (shipping marks), and specific packaging quantities per box.
Streamlined Order Process
Specification Confirmation: Verify technical drawings, size combinations, pressure classes, and applicable regional standards.

Secure Export Delivery: Optimized container loading and durable packaging for international transit.
Frequently Asked Questions
Q: What is the MOQ (Minimum Order Quantity) for custom PP-R tee fittings?
A: Standard sizes usually start at 1,000 pieces per item. For fully customized colors or private-label laser printing, the MOQ is evaluated based on specific production batches.
Q: Can we request free samples before placing a bulk order?
A: Yes, free material and size samples can be supplied for laboratory or quality testing. Clients only need to cover the international courier shipping cost.
Q: What is the typical lead time for container shipments?
A: Standard production typically takes 15 to 25 days after order confirmation and deposit receipt, depending on the total order volume and customization complexity.
Q: What quality inspection reports or certificates are provided with shipments?
A: Every production batch undergoes strict factory testing for burst pressure and dimensional tolerance. Material test reports (MTR) and third-party inspection documents can be provided upon request.
Q: Are PP-R equal tees and reducing tees compatible with all standard fusion machines?
A: Yes. Our fittings are manufactured to standard DIN and ISO dimensions, ensuring smooth compatibility with any standard socket fusion welding machine used globally.
