Buy brass PE pipe fittings — Guide& Tips
In this category you will find around 140 different brass PE pipe fittings – one of the most sought-after connection techniques for water pipes in the home, garden and industrial sectors. The fittings are made of corrosion-resistant brass and are specially designed for PE pipes (polyethylene), which are frequently used in drinking water installations, irrigation systems and compressed air technology. Thanks to the compression fitting technology, the connections can be made quickly and reliably without soldering or welding – ideal for DIY enthusiasts and professionals.
What should you look for when buying? The key factors are the dimensions: PE pipe is selected by outer diameter (e.g., 20 mm, 25 mm, 32 mm, 40 mm) and the fitting by pipe size and thread (male thread or female thread). Check beforehand whether the component is suitable for drinking water and certified according to DVGW or other recognized standards – this guarantees long-term tightness and safety. The most important designs are elbows, tees, couplings, and wall brackets. For connecting PE pipes at house connections, garden lines, or irrigation systems, you usually need a combination of coupling and elbow. A coupling connects two pipe sections, an elbowenables direction changes by 90°, and a T-piece allows branches. For mounting on walls or in shafts, there are special wall brackets and accessories.
As a rule of thumb: Brass PE pipe fittings are designed for continuous operation at pressures up to 16 bar (depending on pipe type and temperature). Ensure a clean, burr-free pipe edge and tighten the union nut hand-tight – excessive force can impair the clamping effect. With proper preparation, you will achieve a permanently tight connection that remains reliable even in soil or damp environments.
Popular Brass PE Pipe Fittings
These three product types cover the most common applications – from house connections to garden sprinkler systems. The selection shows the range of variation in size and thread type.
The 90° elbow is particularly suitable for direction changes on house walls or in shafts, while the couplings with external or internal thread establish the connection to fittings or other systems. The sizes shown (40 mm and 25 mm) represent the two best-selling pipe diameters in the DIY and professional sectors. Note: For 32 mm pipes or special dimensions, you will also find suitable fittings in this category – the item count of 140 covers almost all common combinations.
Frequently asked questions
Which PE pipe diameters fit the brass fittings?
Most brass PE pipe fittings are designed for the common outer diameters of 20 mm, 25 mm, 32 mm and 40 mm. These dimensions correspond to the usual PE pipes for drinking water and irrigation applications. In the product list you will find different versions (elbow, coupling, tee) for each diameter. Make sure that the specified pipe diameter exactly matches the clamping range – a pipe that is too thick or too thin will impair the seal. If in doubt, check the product description or compare with the existing pipe.
What does "DVGW-tested" mean for these fittings?
DVGW (German Technical and Scientific Association for Gas and Water) is a recognized testing institute for drinking water installations. A DVGW certification confirms that the fitting meets the strict requirements for material resistance, pressure resistance and hygienic safety. If you use the connection in a drinking water line, you should definitely use DVGW-tested products – this ensures long-term drinking water quality and complies with the requirements of the German Drinking Water Ordinance (TrinkwV). Many of the brass PE pipe fittings offered here are correspondingly certified.
How do I correctly install a brass PE pipe fitting?
Installation follows the clamping principle: First, cut the PE pipe to length at a right angle and deburr it using a pipe cutter or a fine saw. Then slide the union nut and the clamping ring (often also called "grip ring") loosely onto the pipe. Insert the pipe into the fitting body until it stops – the O-ring provides the seal. Then tighten the union nut hand-tight; a torque of about 30–50 Nm is usually sufficient. Overtightening can damage the O-ring. Retightening after a few hours of operating pressure ("settling behavior") is recommended but not mandatory.
Can I also use brass PE pipe fittings outdoors or in the ground?
Yes, brass is corrosion-resistant and well suited for damp environments such as garden irrigation, basement shafts or overhead lines. For direct underground installation, however, you should additionally use corrosion protection (e.g., bitumen coating or protective sleeve), as aggressive soil components can attack the surface. The fittings themselves are pressure-tight and UV-resistant – the PE pipes are generally not. Therefore: For above-ground outdoor installation, use UV-protected PE pipes or cover the lines. Regular visual inspection for damage increases the service life.
Other categories
The Category Fittings + PE Pipe Connections is the overarching category that includes brass as well as other material variants. If you are looking for lighter or more cost-effective alternatives, take a look at the PP PE Pipe Connections (polypropylene). These are more chemically resistant and especially suitable for rainwater or industrial applications where drinking water requirements do not apply. For pure compression fittings without threads (e.g., in garden irrigation), pure PE fittings are also available. The choice between brass and PP depends on pressure, temperature, and intended use – brass is mechanically highly durable and retains its shape even at higher temperatures, while PP is somewhat more flexible and more corrosion-resistant to many chemicals. Weigh whether the additional cost for brass is necessary for your project or whether a PP fitting is sufficient.
