Blast Hose Couplings

(13 Products)
Blast hose couplings for secure hose connections

Blast hose couplings connect blast hoses to one another or provide the connection to the blast pot and other components. They must be technically suitable for the blast hose, operating pressure, and connection being used, and must ensure a reliable connection during abrasive blasting operations.

The product range includes couplings made of nylon, malleable cast iron, and bronze for various outer diameters of blast hoses, as well as versions with female threads. It also includes matching seals and hose safety restraints.

Before purchasing, the hose size, connection type, and material of the existing connection should be clearly determined. Worn seals should also be checked during maintenance.

Which blast hose coupling is the right one?

✅ Blast hose coupling compatible with the outer diameter of the blast hose

✅ Threaded coupling compatible with the existing system connection

✅ Use a seal that matches the coupling series

✅ Take the hose safety cable into account for suitable connections

Blast hose couplings as mechanical connections in the blasting system

In professional systems, blast hoses are often connected using special blast hose couplings. These couplings must not only carry compressed air but are also part of a system in which abrasive media is transported at high speeds. A proper, leak-tight connection is therefore essential for performance, wear resistance, and operational safety.

Couplings for various blasting hose sizes

Hose couplings are generally selected to match the outer diameter of the blast hose. The product range includes various sizes for different hose dimensions. Two coupling halves can only work together reliably if their design, size, and sealing system are compatible with one another.

The inner diameter of the blast hose affects the flow cross-section, while the outer diameter is relevant for the mechanical installation of the coupling. Therefore, these two measurements should not be confused.

Nylon, malleable cast iron, and bronze

Blast hose couplings are available in a variety of materials. Nylon is lightweight and is used in many hose couplings. Malleable cast iron is robust and is found, among other things, in larger or threaded connections. Bronze is used in certain connection types. The material required depends primarily on the coupling design and the existing system.

Couplings with Female Threads

In addition to direct blast hose couplings, there are versions with female threads that provide a connection to piping, fittings, or blast pot components. The product range includes various inch sizes. When replacing a coupling, the thread must be clearly matched to the existing connection.

Seals as Wear Parts

Matching rubber seals are located between the coupling halves. They ensure a tight connection and prevent unnecessary compressed air leaks. Frequent coupling, aging, and mechanical stress can cause the seals to wear out. A damaged seal should be replaced in a timely manner before leaks or excessive wear on the coupling occur.

Check Before Buying a Coupling

✅ Outer diameter of the blast hose

✅ Coupling type and mating component

✅ Thread size for system connections

✅ Compatible gasket for the coupling series

✅ Condition of existing hose ends and fasteners

Hose safety restraints for compatible hose connections

For compressed-air hoses, additional hose safety restraints may be recommended or required to limit the movement of a hose that has become unintentionally disconnected. Whether such a device is used—and which one—depends on the hose size, the connection, and operational requirements.

Buy blast hose couplings compatible with your existing system

ABS Strahltechnik offers couplings, seals, and complementary connection components for professional blast hoses. By providing information on the hose’s outer diameter, the existing coupling series, and the thread type, you can reliably determine the required model.
