Branches
In this category, discover branch fittings for PVC pipes, including 45° and 90° T-pieces as well as cross sockets and outlet distributors for sanitary and irrigation systems. Expert advice helps you select the right connection technology, whether it's a solvent weld fitting or a PVC threaded fitting made of PVC-U.
Buy branching pieces — guide& Tips
In the category branching pieces you will find 61 articles for professional and private piping with PVC fittings. Whether you are setting up an irrigation system in the garden, installing a sanitary system in the basement, or equipping a workshop with a water connection – the choice of the right branch fitting determines tightness, flow rate, and installation effort. The most common types are T-pieces at 45° and 90° angles, which allow a change in direction or splitting of the water flow. There are also cross sockets that connect four connections on one level, as well as special PVC outflow distributors designed as branch fittings with multiple outlets.
The material of most branch pieces is PVC-U (rigid, chlorine-free polyvinyl chloride), which is characterized by high chemical resistance, UV stability, and pressure resistance. Two techniques are available for connection: glue fittings (connection with PVC cement) and PVC screw connections (detachable connection with sealing ring). Glue fittings are suitable for permanent, pressure-tight installations, while screw connections are useful when you want to dismantle or expand the pipes later. When selecting, pay attention to the nominal diameter (DN) of your pipes – common sizes range from 20 mm to 110 mm. For garden irrigation systems, 25 mm and 32 mm are typical; for household sanitary installations, 40 mm to 50 mm.
A common mistake when buying: branch pieces are chosen based on appearance rather than pressure rating. For drinking water installations, you need fittings with DVGW approval; for rainwater or irrigation, standard PVC fittings are sufficient. Also check whether the branch piece needs to be UV-resistant for outdoor use – many PVC-U fittings are inherently UV-resistant, but not all. If you need flexible pipe connections or reducers, it's worth looking into the sibling categories like Sockets + Adapters or Reducers. For closing pipe ends, you will find suitable Caps + Plugs.
Popular branch pieces
The products shown are examples of the range of the category: While end caps and pipe plugs serve as closing elements, flexible couplings and reducing couplings are needed when you want to connect pipes of different diameters or require a detachable connection. For pure branching tasks – i.e., dividing a pipe run – use T-pieces or cross sockets. Ensure that the nominal width of all connected pipes matches that of the branch piece. For glue fittings, a suitable PVC glue from the category Clamps + Glue + Cleaner is additionally required.
Frequently Asked Questions
Which branch piece do I need for my irrigation system?
For garden irrigation with PVC pipes (usually 25 mm or 32 mm), use a 90° T-piece if you want to branch off a side line. For gentle direction changes, a 45° T-piece is better as it causes less pressure loss. Make sure the branch piece is made of PVC-U and is UV-resistant – this is the case with most fittings in this category. If you are connecting drip hoses or thinner lines, you will also need a reducing fitting.
Can I combine a glue fitting and a screw connection?
Yes, that is possible and common in practice. For example, you can mount a T-piece as a glue fitting and provide a screw connection at one connection to later connect a hose or valve. Note that glue fittings require a clean, degreased surface and sufficient drying time (at least 24 hours before pressure load). Screw connections, on the other hand, are immediately tight and can be loosened at any time. For drinking water installations, we recommend using only tested fittings.
What is the difference between a T-piece and a cross sleeve?
A T-piece has three connections in a T-shape (one inlet, two outlets or vice versa) and is used to extend a pipe line laterally. A cross sleeve has four connections in one plane and allows splitting a pipe line into two opposite directions. Cross sleeves are rarer and are mostly used in complex plumbing or irrigation systems where multiple lines need to be distributed in a tight space. For most DIY projects, a T-piece is sufficient.
Which size fits my PVC pipe?
Measure the outer diameter of your pipe with a caliper. Common sizes are 20 mm, 25 mm, 32 mm, 40 mm, 50 mm, 63 mm, 75 mm, 90 mm, and 110 mm. The branch piece must have the same nominal diameter – for solvent weld fittings, the pipe is inserted into the socket; for screwed connections, it is secured with a union nut. If you want to connect pipes of different sizes, you need a reducer or a reducing coupling. The category Reducers offers suitable transitions.
Further categories
The category Branch pieces is part of the range PVC Fittings + Connectors, which includes all components for piping with PVC pipes. If you need closures in addition to branches, you will find suitable end caps and pipe plugs in the category Caps + Plugs For connecting pipes of different diameters or for transitioning to threads, we recommend the category Sleeves + Adapters. These sibling categories usefully complement the junction pieces when you install a complete pipeline – from the main run through branches to the end closure. For shut-offs and controls, Ball Valves + Gate Valves are available.
In short
In this category with 61 items you will find PVC-U branch pieces in the versions 45° and 90° elbow, cross socket and outlet distributor. The connection is made either as a solvent weld fitting or PVC screw connection. The decisive factors for the correct choice are the pipe diameter (20–110 mm), the installation location (indoor/outdoor, drinking water/irrigation) and the desired installation method. For detachable connections or transitions to other diameters, refer to the sibling categories sockets + transitions and reducers. For solvent weld fittings, ensure compatible adhesive and sufficient curing time.
