PVC pressure hoses
PVC pressure hoses connect compressors, compressed-air tools and systems for air, liquids or chemicals. The listed variants differ primarily by their 6x12, 9x15 or 13x20 mm cross-section and by their length of 10, 25 or 50 meters.
Determining the right pressure hose
A pressure hose is selected using three practical specifications: inner and outer diameter, length, and a version with or without a coupling. The product details in this range name PVC as the material, cross-sections of 6x12, 9x15 and 13x20 mm, and lengths of 10, 25 and 50 meters. For that reason, first check your equipment's connection and the flow rate you need. Only then decide on the length of the hose route and whether you want a pre-assembled coupling.
PVC pressure hose 6x12 mm
This version has an inner diameter of 6 mm, an outer diameter of 12 mm and is 25 meters long. Its product card lists PVC, flexible industrial use and a weight of 2.88 kg.
PVC pressure hose 9x15 mm
Here, the cross-section is 9x15 mm and the length is 25 meters. The product details list PVC, a flexible design and a weight of 3.48 kg.
PVC pressure hose 13x20 mm
This 25-meter version measures 13x20 mm, weighs 5.44 kg according to its specification and is stated for a working pressure of up to 15 bar. PVC and flexible handling are also documented.
Cross-sections and technical distinctions
The first value of a dimension pair denotes the inner diameter and the second the outer diameter. A 6x12-mm hose therefore has a different internal opening than a 9x15-mm or 13x20-mm version. A larger inner cross-section offers more volume per hose length, while a smaller cross-section takes up less space and weighs less. The connection at the equipment remains decisive: the hose connector must match the existing olive, threaded or coupling profile. The product descriptions name compressors, compressed-air tools and the transport of air, liquids and chemicals as fields of application.
When each size fits
For short distances and compact connections, the 6x12-mm version comes first. The medium 9x15-mm cross-section lies between compactness and larger volume. The 13x20-mm version has the largest inner cross-section among the dimensions named. Compare these values with your consumer's data sheet instead of choosing by the outer diameter alone.
Length, weight and handling
According to their product details, the range contains hoses measuring 10, 25 and 50 meters. Shorter routes require less storage space and remain easier to handle. A longer line creates more distance between the supply unit and workplace, but increases transport weight. The three linked 25-meter cards weigh 2.88, 3.48 and 5.44 kg. At 50 meters, weight and the space required for movement also increase. Therefore plan for the actual route, bending radius and storage. A hose without a coupling can be freely integrated into existing connectors, while models with a coupling arrive already assembled.
Applications and media
The product descriptions assign the PVC hoses to compressed-air technology, industry and agriculture. Several versions also mention food-related applications. Air, liquids and chemicals are named as media. Even so, the specific product specification always determines temperature, pressure and medium. One model may be specified for a working pressure of up to 15 bar, while other cards do not show this value. Do not therefore automatically transfer information from one item to every variant. Also pay attention to mechanical stress at edges, sharp bends and tensile forces when planning the route.
Frequently asked questions about pressure hoses
What do specifications such as 13x20 mm mean?
The first number is the inner diameter and the second the outer diameter. At 13x20 mm, the wall thickness calculates as 3.5 mm per side. This specification helps when comparing flow volume, flexibility and suitable threaded fittings.
How long should the hose be?
Measure the actual distance between the supply unit and place of work, and leave room for bends. Ten meters suit shorter routes, 25 meters medium distances and 50 meters extensive areas. A longer hose weighs more and needs correspondingly more floor space.
Are all models fitted with a coupling?
No. The range includes hoses with a coupling and versions without this pre-assembly. The product name only includes the addition “with coupling” when it applies. Without a coupling, existing connection parts can continue to be used.
Why is the material PVC?
The listed pressure hoses are specified as PVC versions. The product descriptions associate this material with flexible handling and use with air, liquids or chemicals. Technical limits appear on the respective product page.
