Popular Fittings + PE Pipe Fittings Categories at a Glance
Brass PE Pipe Fitting
Check the respective product information for the properties and certifications important for your selection. The compression fitting is simply pushed onto the PE pipe and secured. Suitable for irrigation, sprinkler systems, and sanitary installations.
PP PE Pipe Fittings
PP fittings (polypropylene) are lighter and cheaper than brass, but also pressure-resistant and chemical-resistant. They are ideal for irrigation systems, suction lines, and use in horticulture. Assembly is tool-free by pushing on and clamping.
Choose the appropriate variant depending on pressure load and application location.
Brass Fittings: Robustness for Drinking Water and Pressure Lines
Brass compression fittings are the first choice when it comes to permanent tightness and high pressure resistance. The brass fittings are suitable for both pressure and suction lines and are used worldwide – from household water supply lines to garden irrigation systems.
Installation is extremely simple: slide the PE pipe onto the fitting and hand-tighten the union nut. The clamping action creates a reliable connection that remains leak-proof even during temperature fluctuations. When selecting, pay attention to the correct nominal diameter – common sizes are 20 mm, 25 mm and 32 mm. For threaded connections, you need combination fittings with internal thread (IG) or external thread (AG).
Eurokonus compression ring fitting with nut 14 x 2
Compression ring fitting for 14x2 mm pipe with 3/4 inch union nut – suitable for heating pipes and drinking water lines.
When selecting a brass fitting for your project, check the pressure rating: most fittings are designed for operating pressures up to 16 bar. In this category, under Brass PE Pipe Fittings, you will find a wide variety of sizes and designs.
PP fittings: lightweight, corrosion-free and versatile
Polypropylene (PP) is a plastic characterized by low weight, high chemical resistance, and easy processing.
Assembly is tool-free: push the PE pipe into the fitting until it stops and tighten the union nut. The PP clamping rings ensure a tight connection that holds even under light vibrations. Note that PP fittings are only partially suitable for drinking water – here brass or special PP materials with DVGW approval are the better choice. However, they are perfect for irrigation purposes and rainwater harvesting.
Press jaw TH profile, composite pipe press jaw, hand press jaw
Hand press jaw for TH press fittings – suitable for composite pipes and PE pipes with clamp connections. Facilitates the assembly of screwed fittings.
PP screwed fittings are available in various nominal diameters from 20 mm to 63 mm. For connection with other materials such as brass or stainless steel, you will find transition pieces. An overview of all PP variants can be found under PP PE pipe screwed fittings.
Tips & Useful information
Choosing the correct sizing
PE pipes have an outer diameter that determines the nominal size – for example 20 mm, 25 mm or 32 mm. The screwed fitting must be precisely matched to this diameter. Measure the pipe before purchase with a tape measure or caliper. Fittings that are too large lead to leaks, while those that are too small cannot be installed. For irrigation lines in the garden, 20 mm or 25 mm are common, for main lines 32 mm or larger.
The seal is what matters
Most compression fittings use an O-ring or a plastic compression sleeve. Before installation, check that the seal is undamaged and seated correctly. For brass fittings, EPDM O-rings are approved for drinking water. For PP fittings, the seals are often integrated. Lightly greasing the O-ring with a silicone-free lubricant makes it easier to push the pipe on.
Assembly instructions for compression fittings
Cut the PE pipe cleanly and at a right angle using a pipe cutter. Deburr the cut edge to avoid damaging the seal. Push the pipe into the fitting as far as it will go – often there is a marking on the fitting. Tighten the union nut hand-tight; overtightening can deform the pipe or crush the seal. If necessary, you can retighten the connection with a wrench, but only with a feel for it.

Frequently asked questions
What is the difference between brass and PP fittings?
Brass fittings are metallic, very robust and corrosion-resistant. PP fittings are made of plastic, are lighter and cheaper. They are ideal for irrigation, suction lines and horticulture because they do not rust and are chemical resistant. For drinking water, only special PP variants with approval are suitable. The choice depends on the application, pressure and budget.
Can I use PE fittings for drinking water as well?
Yes, but only if the fitting is explicitly approved for drinking water. PP fittings are usually not suitable for drinking water unless they carry appropriate certification. Pay attention to the product description and test seals. For irrigation, rainwater harvesting or industrial applications, both materials can be used without restriction.
Which pipe sizes fit the fittings?
PE compression fittings are dimensioned according to the outer diameter of the pipe. Common sizes are 20 mm, 25 mm, 32 mm, 40 mm and 63 mm. Measure your pipe accurately – the specification in inches (e.g. 3/4 inch) refers to the thread, not the pipe diameter. For 20 mm pipes you need a 20 mm fitting. For combination fittings with thread, the thread size (e.g. 1/2 inch, 3/4 inch, 1 inch) is also given.
How do I install a PE compression fitting correctly?
Cut the PE pipe at a right angle with pipe cutters and deburr the edge. Slide the union nut and compression ring onto the pipe. Insert the pipe all the way into the fitting – a marking is often visible. Tighten the union nut hand-tight. Do not use tools to over-tighten the nut; if necessary, you can tighten it slightly with a wrench. Check the seal after installation by pressure test.
Are PE fittings reusable?
In principle, compression fittings are designed for single use. After loosening the connection, the clamping ring may be deformed and the seal damaged. For reuse, you should use new clamping rings and seals. For brass fittings, you can purchase the O-rings separately. PP fittings are often designed as disposable components. For permanent installations, it is recommended not to loosen the fitting once it is tight.
In short
The category 'Fittings + PE Pipe Fittings' includes 940 items for pressure and suction lines in the areas of plumbing, irrigation, and drinking water.
