Kingdaflex provides a strong and durable abrasive sandblasting hose with maximum air pressure and optimum lifespans. Don’t settle for an old thinning hose for your tough jobs. Kingdaflex carries the top two abrasive blasting hoses on the market: the 2-ply and 4-ply. 

With tough exteriors and reinforced inner-liners, find the length you need from our selection of powerful blasting equipment below.

Sandblasting is a process that involves the use of abrasive materials to smooth or clean surfaces. It requires the use of specialized equipment, including a sandblast hose, to effectively complete the task. However, with so many options available on the market, choosing the right sandblast hose can be overwhelming.

In this article, we will guide you through the process of choosing the best sandblast hose for your needs.

Determine the Size and Type of Abrasive Material

The size and type of abrasive material that you will be using will play a significant role in determining the size of sandblast hose you need. Larger abrasive materials require a larger hose, while smaller abrasive materials require a smaller hose. Additionally, different types of abrasive materials require different hose materials. For instance, if you plan to use steel shot as your abrasive material, you’ll need a hose that can handle the heavy weight.

Consider the Pressure and Velocity

The pressure and velocity of the abrasive material will also determine the type of sandblast hose you need. Higher pressure and velocity require a hose that can handle the increased demands. A hose that is too weak can easily break under high-pressure conditions, leading to accidents and injuries. Therefore, it’s crucial to choose a hose that is specifically designed to handle the pressure and velocity of your abrasive material.

Evaluate the Temperature and Climate Conditions

Another important factor to consider is the temperature and climate conditions of your worksite. Extreme temperatures and harsh weather conditions can cause the sandblast hose to degrade quickly, leading to reduced efficiency and an increased risk of accidents. It’s essential to choose a hose that can withstand the temperature and climate conditions of your worksite.

Check for Compatibility

Compatibility is a critical factor when choosing a sandblast hose. The hose must be compatible with both the abrasive material and the equipment being used. Incompatible hoses can lead to reduced efficiency and increased risk of accidents. It’s essential to ensure that the hose you choose is compatible with both the abrasive material and equipment to avoid any unwanted incidents.

Look for Quality and Durability

Finally, it’s essential to choose a sandblast hose that is of high quality and durable. A quality hose will have a longer lifespan, reducing the need for frequent replacements and repairs. Additionally, a durable hose will be able to withstand the high-pressure conditions of sandblasting, reducing the risk of accidents and injuries.


Note that the hose should be 3 times bigger than the nozzle size. Check the hose ID to determine how it measures up to the nozzle size. Every Kingdaflex product is clearly labeled and we also offer a selection of quality nozzles. Improper sizing causes unnecessary wear and tear on the inside of your blasting tube which leads to a shorter lifespan for your equipment. Proper sizing not only increases the lifespan but ensures that the air pressure is not lost from hose to surface.

Contractors need two hoses for abrasive blasting jobs and each requires a different length to ensure the best blasting power. The first hose is the one attached from the air compressor to the blast pot and the second hose runs from the blast pot to your work surface. The first hose is typically longer and requires a larger ID size because the compressor, unlike the blast pot is not highly portable.

A longer hose from the compressor to the blast pot gives your more mobility and the larger ID ensures that the blasting medium gets to the pot. The second hose from the blast pot to the work surface should be short, so you can get the maximum amount of pressure from the hose.

2-Ply Hoses

2 Ply Hose
2 Ply Hose

Kingdaflex Blasting, your one-stop shop for serious sandblasting equipment, provides a hardy line of  2-ply blast hoses. The Kingdaflex 2-ply hose accepts properly-sized couplings and nozzles and is compatible with all forms of blast media. In terms of hose size offerings, the 2-ply lies between the supa hose and 4-ply line. Whereas the supa is a skinnier and more flexible hose, the 2-ply hose offers a stiffer alternative for serious abrasive blasting jobs. But in comparison to 4-ply hoses, the 2-ply offers increased flexibility without sacrificing durability.

Each 2-ply hose comes with reinforced features, just like our 4-ply series, and is often used for similar industrial jobs.

A 2 ply sandblasting hose is made with two liners:

An abrasive-resistant natural rubber liner consisting of two layers

A high tensile, textile cord-reinforced liner. As mentioned above, the cover of the hose is weather, ozone, and abrasion resistant. The small inside diameter sandblasting hose can be used for shorter runs and as a sandblasting cabinet hose. It can also be used as your “whip hose,” or the final 10 to 15 ft at your blast nozzle for better control.

Our 2 ply sandblasting hose is sold in 10″, 25″, 50″, 100″ and bulk 200″ +/- 6 inches.

Working Pressure: 217 psi.

In any pressure blast system, your blast hose should be three or four times the ID of your nozzle orifice. Choosing the right size for your blast hose has 2 major benefits – it prolongs the life of your hose and helps maintains adequate pressure at the blast nozzle.

4-Ply Hose

4 Ply Hose
4 Ply Hose

If you’re in the market for a serious piece of abrasive blasting equipment with more support and higher pressure than a 2-braid or Supa hose, then the 4-ply abrasive blasting hose is the natural next step.

Our 4 ply blast hose is made with two liners:

An abrasive resistant natural rubber liner consisting of four layers with a high tensile

A textile cord-reinforced liner.

The casing is weather, ozone, and abrasion resistant, making it the ideal piece of blasting equipment for industrial settings. Crewmen typically move up to the 4 ply hose when working near railroads or shipyards knowing they can rely on the reinforced exterior. This blast hose is tough enough to withstand the typical weathering caused from dragging and won’t collapse under the weight of light traffic.

The 4 ply sandblasting hose is sold in 10″, 25″, 50″, 100″ and bulk 200″ lengths +/- 6 inches.

Work pressure: 290 psi. The Kingdaflex 4-ply hose can be paired with any standard couplings, nozzle holders or blasting machine. Due to the high tensile, the 4 ply hose is typically paired with other attachments to increase flexibility on the job. The twin hose and dead man control, which are sold separately, are our top pairing items for this blast hose.

Each attachment provides increased control when moving about the blast site which ensures a safer workspace. Because the 4 ply blast hose is rarely purchased alone, take advantage of the blasting inventory at Kingdaflex and get all of the parts you need for the hose from one location.


In conclusion, choosing the right sandblast hose is crucial to ensure the safety and efficiency of your sandblasting process. By considering the size and type of abrasive material, pressure and velocity, temperature and climate conditions, compatibility, and quality and durability, you can choose the best hose for your needs. Remember to always prioritize safety when working with abrasive materials and equipment.
