Mortar Couplings

Mortar couplings are a specialist type of industrial hose
fitting used to connect mortar, grout, or plaster hoses to machinery or other hose assemblies. Unlike standard hose fittings, these couplings are designed to
endure the extreme abrasion, pulsating pressure, and harsh materials associated with wet cement and mortar applications.

Mortar couplings typically feature:

• Heavy-duty construction using forged steel or ductile iron
• Interlocking clamp designs for vibration resistance
• Integrated gaskets or seals for leak protection
• Tapered or flanged ends to suit cement hose specifications

Their primary purpose is to maintain a tight, secure seal during high-pressure transfer of abrasive materials such as sanded mortar, grout, concrete mix, and similar compounds. Without the correct couplings, hose connections can leak, wear prematurely, or fail under pressure — causing safety risks and costly downtime.

At Integraflex, we stock a range of mortar couplings to
suit different hose sizes, pressure ratings, an connection preferences. Some of the most used types include:

• Claw Mortar Couplings – These interlocking claw-style couplings offer a quick-connect solution ideal for construction sites. Their rugged design and snap-fit mechanism provide secure sealing and fast assembly/disassembly.

Flanged Mortar Couplings – Flanged ends are typically used when attaching mortar hoses to fixed equipment, tanks, or pump outlets. They offer a secure, high-strength connection for static installations.

• Bolt Clamp Couplings – Designed for very high pressure or heavy-duty applications, bolt clamp styles use multiple fasteners to ensure a tight seal and resist hose movement or vibration.
• Tapered Cement Hose Couplings – Tapered or serrated ends provide maximum grip inside the hose bore, reducing the risk of slippage under pressure and ensuring durability in demanding applications.

All of our industrial hose fittings are designed with ease
of use and system longevity in mind. Whether you’re fitting new mortar equipment or replacing worn parts, we have the couplings you need to maintain productivity on-site.

Mortar couplings are used in a wide variety of
construction, tunnelling, and civil engineering projects. Any application involving the high-pressure transfer of abrasive mixtures such as mortar, concrete, or grout requires couplings that can endure tough conditions without compromise.

Common use cases include:

• Concrete and mortar pumping – Secure connections between pumps and hoses used to deliver wet cement and mortar to work areas
• Tunnelling and mining – Sprayed concrete applications (shotcrete) for structural support or lining
• Rendering and plastering – Transport of plaster and render from mixing units to spray guns
• Tile bedding and screeding – Grout hose connections for laying large-scale tile, brick, or flooring installations
• Civil engineering and piling – Transfer of grout mixtures for structural foundations and reinforcement

Because of their exposure to vibration, pressure surges, and highly abrasive materials, cement hose couplings must be tough, reliable, and resistant to both chemical attack and mechanical wear.

Selecting the right mortar coupling depends on
several important factors:

Hose diameter and type – Ensure compatibility with your hose size, wall thickness, and reinforcement type

Working pressure – Match the coupling rating to the maximum operating pressure of your mortar or grout system

Connection type – Choose claw, flanged, or clamped styles depending on your equipment and workflow

Material – Opt for high-wear metals such as ductile iron or steel for long-lasting durability

Frequency of use – Quick-release styles may be preferable for regular assembly and disassembly

Environment – Consider corrosion resistance if working in wet, marine, or chemical-heavy environments
