POM plastic hose connectors
Here you will find a selection of hose connectors made of sturdy POM plastic for garden irrigation – including T-pieces, elbows and couplings for various hose diameters. The connectors are durable and suitable for outdoor use.
Buying POM plastic hose connectors — Guide & Tips
In the category POM plastic hose connectors you will find 235 items for garden irrigation, outdoor use, and technical applications. POM (polyoxymethylene) is an engineering plastic with high strength, low water absorption, and good dimensional stability. These connectors are therefore particularly suitable for long-term outdoor use, under temperature fluctuations and mechanical stress.
The selection of the right connector depends on three factors: Hose diameter, connection type, and place of use. Common diameters range from 5 mm to 19 mm. For straight connections use hose barb connectors, for direction changes angle connectors (90° or 45°) and for branches Y-pieces or T-pieces. Make sure the connector matches the inner diameter of your hose – barbs that are too large will cause leaks, while ones that are too small will allow the hose to slip off.
POM plastic is more UV-resistant than many other plastics, but not unlimited. Check the respective product specifications for the properties and certifications important for your selection. Most POM connectors are suitable for pressures up to 6–8 bar – sufficient for standard household garden pumps and irrigation systems. For higher pressures or industrial applications, you should use brass connectors instead.
A common mistake when buying: confusing outer and inner diameter. Always measure your hose at the end – not in the middle where it may be stretched. Use a caliper for precise values. With 235 items in this category, you will find the right connector for almost every standard diameter. The category Connectors + Accessories additionally offers seals, adapters, and mounting aids that make installation easier.
Popular hose connectors POM plastic
These three product types cover the most common applications: The straight hose connector is the standard for extensions and repairs. The Angle connector solves space problems at obstacles and protects the hose from kinking. The Y-piece distributes water to two lines – essential for simultaneous watering of multiple areas. For finer diameters under 10 mm, it is recommended to check compatibility with your hose system, as micro-irrigation often requires special connections.
Frequently asked questions about hose connectors made of POM plastic
What advantages does POM plastic offer over other materials?
POM (polyoxymethylene) is characterized by high strength, low moisture absorption, and good dimensional stability. Unlike PVC or polyethylene, POM hardly deforms under pressure and remains dimensionally stable even with temperature fluctuations. Compared to brass, POM is lighter, corrosion-free, and cheaper. For typical garden use with pressures up to 8 bar and temperatures from -20 to +80 °C, POM is the optimal choice. However, under continuous exposure to UV radiation, you should use specially stabilized variants.
How do I find the right diameter for my hose?
Measure the inner diameter of your hose using a caliper or vernier caliper. Common sizes are 5 mm, 9 mm, 13 mm and 19 mm. The connector should be slightly larger than the inner diameter so that the nozzle fits tightly. For 19 mm hoses, use a 19 mm connector. Be careful not to overstretch the hose – a connector that is too large will cause cracks. The 235 items in this category cover all standard diameters. If in doubt, choose a connector with a union nut or hose clamp for additional security.
Can I leave POM connectors outside in winter?
POM plastic is frost-resistant down to about -20 °C, but not indefinitely. With repeated freeze-thaw cycles, the material can become brittle. It is recommended to dismantle the connectors before winter or at least drain the hoses to avoid standing water in the connectors. If the connectors are tight and no moisture can penetrate, they will survive mild winters without problems. In severe areas or during permanent frost, you should bring the connectors to a dry place.
How do I properly seal a POM hose connector?
Most POM connectors do not require additional sealing because the nozzles seal tightly due to their conical shape and ribbing. For smooth hoses or higher pressure, you can wrap Teflon tape on the thread (if present) or a hose clamp attach over the hose at the connector end. Make sure not to tighten the clamp too much – otherwise the plastic may be damaged. Hand-tight plus half a turn is sufficient.
Other categories in the area of connectors + accessories
In addition to the POM hose connectors, the category connectors + accessories offers several alternatives that may be better suited for specific applications:
- Plastic connectors – These connectors are usually made of PVC or polyethylene. They are cheaper than POM, but less durable.
- Brass connectors – The robust choice for continuous load, high pressure (over 8 bar) and industrial applications. Brass is corrosion-resistant, but heavier and more expensive. Recommended for pump connections and continuous pressure lines.
- Hose clamps – Essential accessory for fixing hoses onto connectors. Increases tightness and prevents slipping, especially with pulsating pressure or vibrations.
When building a permanent irrigation system, combine POM connectors with hose clamps for maximum security. For movable or temporary hoses, the pure clamping connections of the plastic connectors are often sufficient. Brass connectors are worthwhile if you have frequent pressure changes or the system is to remain unchanged for years.
In brief
In the category Hose connectors POM plastic with 235 items, you will find stable, durable connectors for garden irrigation. Choose the connector according to hose diameter (5–19 mm) and connection type (straight, angle, Y-piece). For higher pressures or continuous load, brass connectors are available. Supplement your installation with hose clamps for tight, secure connections. Measure the inner diameter of your hose before purchase – this is the most common mistake and easily avoidable.
