Buy POM plastic hose connectors — Guide&Tips
In the category "POM plastic hose connectors" you will find 216 items specifically designed for use in irrigation technology and sanitary installations. POM (polyoxymethylene) is an engineering plastic characterized by high strength, rigidity, and excellent dimensional stability. Unlike inexpensive soft plastics, POM connectors maintain their fit even under temperature fluctuations and continuous load. They are corrosion-free, which makes them particularly suitable for use in garden irrigation and potable water applications.
When selecting the right connector, you should pay attention to the inner diameter of your hose — the most common sizes in this range are between 12 mm and 19 mm. The shape of the connector determines the flexibility of your piping system: T-pieces are suitable for branches, Y-pieces for distribution over two lines with lower pressure loss, and straight connectors for extensions or repairs. Pay attention to pressure resistance: standard versions are sufficient for rain barrels or low-pressure irrigation systems, while reinforced variants make sense for connection to the house water line.
POM connectors are chemically resistant to most fertilizers and pesticides, making them the first choice forhosesin landscaping and horticulture. The smooth surface prevents deposits and simplifies cleaning. Professionals also appreciate the easy installation without special tools — the connectors are simply inserted into the hose and secured with hose clamps. For permanent installations in sanitary engineering, we additionally recommend corrosion-freeclampsto use stainless steel to ensure an optimal connection.
Popular hose connectors POM plastic
The three presented products represent the most important designs in this category. The T-piece with reducer is the right choice if you want to connect a branch with a smaller diameter to an existing hose – typical for the transition from the main line to drip irrigation. Y-pieces, on the other hand, preserve system pressure because the water flow is divided more gently. The 16 mm connector is the all-rounder for standard household garden hoses, while the 19 mm variant is designed for higher flow rates, for example when filling larger water tanks or in agriculture. Please note: POM plastic is stiffer than conventional PE, so you may need to warm it (e.g., with a hair dryer) when pushing it onto the hose to avoid material stress.
Frequently asked questions about POM hose connectors
What advantages does POM plastic offer over other materials?
POM (polyoxymethylene) is a high-performance engineering plastic with very low water absorption – meaning the connectors do not swell and remain dimensionally stable even with continuous contact with water. Compared to brass or stainless steel, POM connectors are corrosion-free and significantly lighter, which makes handling easier during installation. Compared to cheap soft plastics like PVC, they offer higher impact strength and temperature resistance (from approx. -40 °C to +100 °C). In addition, they are resistant to many chemicals, oils, and UV radiation, making them ideal for outdoor garden use.
How do I choose the right size for my hose?
Measure the inner diameter (ID) of your hose with a caliper. Common sizes in this category are 12 mm, 16 mm, and 19 mm. The connector should fit exactly: connectors that are too small lead to leaks, ones that are too large cannot be attached. For oversize hoses (e.g., 13 mm or 20 mm), check whether the manufacturer specifies tolerances. For drip hoses with thin wall thickness, there are special reduced versions. A tip: take a piece of your hose as a sample or note the type designation to avoid incorrect purchases. In the range of 216 items, you are sure to find the right size.
Can I use POM connectors for drinking water?
Yes, POM plastic is food-safe and is often used in the beverage and food industry. Most POM connectors meet the requirements of the Drinking Water Ordinance, provided they do not contain plasticizers or other harmful substances. Look for products that are explicitly marked as drinking water certified. For use in rain barrels or garden irrigation, this certification is not strictly necessary. However, note: POM ages slowly under direct UV radiation, so we recommend a cover or hoses with UV protection for permanent outdoor installations. Further care tips can be found in our guide Rubber & care for plastic correctly.
Do I need additional seals or glue?
Usually not. POM connectors are installed mechanically via clamp or plug connections. The tightness is achieved by the precision fit of the plastic and the force of a hose clamp. For smooth hoses without a bead or profile, we recommend a stainless steel hose clamp to prevent slipping. Do not use solvent-based adhesives, as these can attack POM. For low-pressure applications such as rain barrels, a simple plug connection without a clamp is often sufficient, as long as the hose fits tightly. For pressurized systems (from 2 bar), clamps are mandatory. Professional installation with clamps from the category Clampsensures permanent tightness.
More categories related to hoses
The hose connectors made of POM are only part of the overall system. If you are planning a complete irrigation or sanitary system, it is worth looking at related categories. The parent category hoses provides an overview of all available hose types and accessories. For special applications, we recommend:
- Suction hose & Pressure hose:For pump connections or systems with overpressure, you need reinforced hoses that can withstand higher loads. These are often equipped with a fabric insert.
- Silicone hoses:Ideal for high temperatures or food contact. Silicone remains flexible even in extreme cold and is more resistant to aging than POM.
Consider the intended use of your installation: for simple garden watering with rainwater, POM connectors and standard PE hoses are optimal. However, if you are using the system indoors with warm water or for chemicals, choose Storz system couplings, which provide a standardized and pressure-proof connection. Also, hose holders can be useful to route lines neatly and avoid kinks that could otherwise shorten the lifespan of your connectors.
In short: hose connectors made from POM
Polyoxymethylene (POM) is a technical plastic characterized by high strength, corrosion resistance, and dimensional stability. In this category you will find 216 different connectors in shapes such as T-pieces, Y-pieces and straight sockets for hose diameters from 12 mm to 19 mm. Typical areas of application are rainwater harvesting, garden irrigation and sanitary installations in the low-pressure range. When selecting, pay attention to the exact diameter specifications and use suitable clamps for a tight connection. POM connectors are chemical resistant and food-safe, but not suitable for continuous loads above 100 °C. For special applications such as suction lines or high-temperature areas, refer to the mentioned sibling categories.
