Shanghai Zhongsu Pipe Co., Ltd., one of China's established 1/2" 3/4" 1" PPR Tee Manufacturers, produces PPR TEE fittings as part of a complete polypropylene-random piping system. Our tee range covers equal, reducing, female threaded and male threaded bodies in 1/2", 3/4" and 1" sizes, with custom pressure ratings up to PN 2.5 MPa. These fittings divide or combine flow at T-junctions in hot and cold water supply, heating and building service lines.
As a PPR pipe tee factory, we also produce the matching PPR PIPE and companion fittings, so a project can be supplied from one manufacturing source with consistent material, dimensions and fusion behaviour across the whole pipeline.
Our PPR Tee Range and Where Each Type Fits
The tee is the branch point of a PPR system, so its type is chosen by the pipe layout rather than by preference. Equal tees keep the branch at the same nominal diameter as the run; reducing tees step down to a smaller branch; threaded tees convert the plastic line to a metal connection at the outlet. We mould all four types from the same Polypropylene Random Copolymer compound used in our pipe extrusion, which keeps weld compatibility predictable on site.
| Tee Type | Typical Application | Connection | Sizes |
|---|---|---|---|
| PPR Equal Tee | Main distribution runs, riser branches, manifold headers | Socket fusion, three ends | 1/2", 3/4", 1" |
| PPR Reducing Tee | Branch take-offs to fixtures, zone valves, smaller sub-loops | Socket fusion, stepped branch | Reduced branch combinations |
| PPR Female Threaded Tee | Connection to metal valves, meters, pumps and equipment | Fusion run, female threaded branch | 1/2", 3/4", 1" |
| PPR Male Threaded Tee | Transition to hoses, manifolds and threaded equipment ports | Fusion run, male threaded branch | 1/2", 3/4", 1" |
Material and Pressure Considerations
Our plastic products use 100% imported raw material from Borealis and South Korea. For a tee, that matters at the weld: consistent melt flow gives a stable fusion bead and repeatable joint strength across a full installation shift. The standard pressure class for these tees is PN 2.5 MPa, and we produce custom pressure ratings where the system design calls for them.
- Temperature service: PPR tees suit hot and cold water distribution; for higher-temperature duty, pair them with PPR PIPE FOR HIGH TEMPERATURE WATER and PP-RCT components.
- Threaded inserts: brass or metal inserts are moulded into female and male threaded tees to carry the torque of metal-to-plastic joints.
- Chemical compatibility: the copolymer resists corrosion and scale in potable and non-potable water circuits, so tees do not need linings or coatings.
- Thermal expansion: branch runs should be designed with the same expansion allowance as the parent pipe, since the tee is rigid and cannot absorb movement.
System Fit: Pipes, Fittings and Accessories
A tee is only one node in a pipeline, so we supply the surrounding components from the same material family. This is how we keep a bill of materials coherent: the tee, the pipe it fuses to, the couplings that join straight lengths, the elbows that change direction and the valves that isolate the branch all come from one production system.
Water Supply Lines
Equal and reducing tees branch potable water risers and floor distribution loops. Pair with PPR PIPE FOR WATER SUPPLY for building service lines.
Heating and High-Temperature Circuits
PP-RCT and high-temperature pipe grades with matching tees for heating risers and hot water circulation.
Equipment Connections
Threaded tees transition the plastic line to valves, meters, pumps and metal ports without adapters.
Quality Control and Acceptance
ZHSU owns a CNAS-certified national laboratory and operates under ISO9001, ISO 14001 and OHSAS18001 management systems, with CE certification listed for the relevant product scope. Production runs under full-process monitoring from raw material intake to finished goods, and every batch is sampled and tested. During production, dimensional and process data are checked at regular intervals, and the quality department performs additional inspections at defined stages — the standard buyers expect from a dedicated PPR pipe tee factory.
- Factory inspection reports are available as quality assurance documentation.
- Sampling tests apply to each batch of goods before release.
- Dimensional checks cover socket depth, wall thickness and thread form on threaded tees.
- Fusion behaviour is verified against the matching pipe grade so site welds meet the same standard as the factory test.
Installation, Packaging and Delivery Scope
PPR tees are joined by socket fusion using a heated tool; the pipe end and the tee socket are melted simultaneously and pushed together to form a homogeneous joint. Correct heating time, insertion depth and cooling time depend on diameter and ambient temperature, and we supply the matching pipe and fittings so the same fusion parameters apply across the joint.
Pipe fittings are first packed in transparent plastic bags in specified quantities, then placed in dedicated cartons. Pipes are bundled and packed in woven bags. Regular pipes and fittings are held in sufficient inventory, so there is no minimum order quantity on standard items; minimum quantities for made-to-order pipe sizes vary by diameter. Typical delivery is around 15 days, confirmed against the order list and current production schedule. We support OEM and ODM work and can supply free samples where the customer has a freight forwarder in China.
Information We Use to Configure Your Solution
To prepare a tee configuration and quotation, we work from the project's own data rather than a generic catalogue selection. The following inputs let us confirm the right type, size and pressure class and quote against the correct trade terms.
- Order list: tee type, nominal diameter, quantity and any reduced-branch combinations.
- Trade terms: FOB, CIF, CNF or other applicable terms for the quotation.
- System duty: hot or cold water, design pressure and temperature class, including whether PN 2.5 MPa or a custom rating is required.
- Connection schedule: which branches are fusion-welded and which require female or male threaded outlets.
- Project context: building type, riser layout and any specification standard the pipeline must satisfy.
- Packaging and marking: carton quantities, labelling and any OEM requirements.
Frequently Asked Questions
What sizes of PPR tee do you manufacture?
As 1/2" 3/4" 1" PPR tee manufacturers, we produce these sizes as standard, in equal, reducing, female threaded and male threaded types. Custom pressure ratings up to PN 2.5 MPa are available, and we can review other sizes against the order list.
Which tee should be used at a branch to a metal valve?
Use a female or male threaded tee, depending on the valve port. The metal insert is moulded into the fitting so the threaded joint carries the required torque, while the run ends remain socket-fusion connections to the PPR pipe.
What raw material is used in your PPR tees?
All plastic products use 100% imported raw material from Borealis and South Korea. This gives consistent melt flow for fusion welding and keeps the tee compatible with the matching ZHSU pipe grades.
How is quality verified before shipment?
Production is monitored from raw material intake to finished goods, with sampling tests on every batch and regular in-process inspections. Our CNAS-certified laboratory supports the testing programme, and factory inspection reports can be provided as quality assurance documentation.
Do you supply the pipe and other fittings with the tees?
Yes. We supply PPR pipes, couplings, elbows, unions and valves alongside the tee range, so a complete pipeline can be sourced from one manufacturer with consistent material and dimensions.
What is the typical delivery time and packaging?
Delivery is typically around 15 days, confirmed against the order list and production schedule. Fittings are bagged in specified quantities and packed in dedicated cartons; pipes are bundled in woven bags. Standard fittings are held in inventory with no minimum order quantity.
