How to Selection the Right Specification?
As a customer, you will definitely want to choose the most appropriate size and model of PVC spring clear hose to ensure that it perfectly matches your usage needs. Below I will explain the size parameters in detail, how to choose, and provide some practical suggestions to help you make the best decision.
Normal Parameters
Inner Diameter (ID)
Common range: 1/2 inch (12mm) → 8 inches (200mm), or even larger.
Common models:
Small (home/light): 1/2″, 3/4″, 1″ (12mm, 19mm, 25mm)
Medium (industrial/agricultural): 1.5″, 2″, 3″ (38mm, 50mm, 75mm)
Large (engineering/mining): 4″, 6″, 8″ (102mm, 152mm, 200mm)
Outside diameter (OD)
Larger than the inside diameter, depending on the wall thickness and wire layer strength.
For example: A hose with a 1″ inside diameter may have an outside diameter of 29mm, 30mm, 32mm(depending on the specific model).
Length
Standard lengths are usually 20m, 30m, 50m/roll, and can also be customized as required (such as 10m, 100m).
How do I choose the right size?
When selecting the size, you need to consider the flow requirements, pressure, media type and installation environment:
Select the inner diameter according to the flow rate (flow velocity)
Principle: The larger the inner diameter, the greater the flow rate, but the cost and weight also increase.
Select wire layer and wall thickness according to pressure
Low pressure (<6 bar): standard wall thickness + ordinary wire spacing (such as agricultural irrigation) can be selected.
High pressure (>10 bar): thickened wall + tight spiral wire (such as industrial cleaning machine) is required.
Select materials according to the medium
Water/air: standard PVC is sufficient.
Oil/chemicals: confirm the chemical resistance of PVC, or choose a special coating lining
Choose flexibility based on the installation environment
Narrow space: choose a small diameter (such as 1″) or a highly flexible model.
Outdoor long distance: choose a large diameter (such as 3″) to reduce pressure loss.
PVC spring clear hose also can equipped with fittings to acheive the efficient usage.
How to confirm the compatibility of the connector?
Provide your equipment interface size (such as thread standard: NPT, BSP, etc.), and we will match the corresponding connector.
We can customize special inner diameters, lengths, color markings etc. If you are unsure, we can send you a small sample for you to try. Welcome to contact us at any time1
