The diameter listed (16mm, 19mm, 25mm, etc.) refers to the outer diameter (OD) of the hose. Match it to your fitting's barb or nipple size. For example, a 3/4" (≈19mm) barb fitting typically pairs with the 19mm hose variant. A 1" barb (≈25mm) fits the 25mm size. Always measure your existing fitting or hose with calipers before ordering to confirm the correct size.

Working pressure varies by diameter and wall thickness. Smaller diameters (16–32mm) generally support higher pressures than larger ones due to the proportionally thicker wall. For pressure-critical applications — such as pump discharge lines, compressed air, or pressurized irrigation — contact us to confirm the rated working pressure for your specific size before ordering.

Yes. This hose is made from a food-grade PVC compound, making it suitable for potable water supply, beverage transfer, and food processing applications. It is generally free of harmful plasticizers that could leach into food or water under normal operating temperatures and pressures. For regulatory compliance in commercial food processing, confirm the specific certification requirements for your application.

Standard PVC is generally not UV-stabilized. Prolonged exposure to direct sunlight can cause the material to become brittle and discolor over time. For outdoor installations, we recommend routing the hose through conduit, wrapping it with UV-protective tape, or shading it to extend service life. For permanent outdoor use, consider a UV-resistant hose alternative.

This hose is compatible with standard metric barb fittings and hose clamps. For inch-based fittings, use these approximate conversions: 16mm ≈ 5/8", 19mm ≈ 3/4", 25mm ≈ 1", 32mm ≈ 1-1/4", 38mm ≈ 1-1/2", 50mm ≈ 2", 75mm ≈ 3", 100mm ≈ 4". Always secure connections with a hose clamp for any pressurized application to prevent blow-off.

Plain PVC hose typically balloons at fittings under pressure and kinks sharply when bent — both of which restrict or stop flow. The internal braid reinforcement in this hose maintains a consistent bore diameter under working pressure and resists kinking under bending stress. This makes it the preferred choice for pump lines, irrigation systems, and any application where the hose must hold its shape without rigid support.

A sharp utility knife or fine-tooth hacksaw gives a clean cut on smaller diameters (16–32mm). For larger sizes (38mm and above), a hacksaw or rotary pipe cutter works better through the braid reinforcement. Always deburr the cut end and smooth any wire protrusions before inserting fittings to ensure a leak-free seal and avoid damaging O-rings or gaskets.
