Imer 4" Mechanical Groved Coupling, 1107179

Features

• Suitable for connecting to single groove coupler
• Provides a lightweight, easily installed connection for joining hose to a standard grooved end piping system, mechanical pipe joining systems and valves or hose-to-hose connections
• The nipple slides easily into the hose and the clamp engages the nipple and around the hose O.D

The Imer 4" Mechanical Groved Coupling (correctly, Imer 4" Mechanical Grooved Coupling), model 1107179, is a genuine IMER mechanical pipe coupling designed to quickly and securely join 4‑inch grooved pipe or hose in pumping and material‑handling systems, especially on IMER pumps and grout/mortar rigs. This 4" grooved coupling provides a lightweight, easy‑to‑install connection compatible with standard single‑groove couplers, making it ideal for joining hose to grooved‑end piping, valves, or hose‑to‑hose configurations on demanding construction sites.

What is the Imer 4" Mechanical Groved Coupling?

Contractors Direct, Blades Direct, and HandGearPro all list this product as “Imer 4" Mechanical Groved Coupling, 1107179” (sometimes with the common misspelling “Groved”), and describe it as an IMER‑branded mechanical grooved coupling for 4‑inch systems. It is used to connect IMER hoses and piping into standard grooved‑end mechanical pipe joining systems, similar to Victaulic‑style couplers.

Key identifiers:

• Product name: Imer 4" Mechanical Groved/Grooved Coupling.

• IMER part number / SKU: 1107179.

• Nominal size: 4 inch mechanical grooved coupling.

Contractors Direct lists it under “Imer Victaulic 4" Coupler,” indicating that it is functionally equivalent to a 4" Victaulic‑type mechanical pipe coupling for grooved connections.

Designed for Grooved Pipe and Hose Connections

The Imer 4" Mechanical GrovedCoupling is specifically intended to interface with single‑groove couplers and standard grooved‑end piping systems:

From the Contractors Direct and Blades Direct product features:

• “Suitable for connecting to single groove coupler.”

• “Provides a lightweight, easily installed connection for joining hose to a standard grooved end piping system, mechanical pipe joining systems and valves or hose‑to‑hose connections.”

In practice, that means the coupling:

• Can be used to connect IMER material hoses to 4" grooved steel pipe or manifolds on pumps and mixers.

• Works within existing mechanical pipe joining systems (Victaulic‑style) often used in industrial and construction pumping applications.

• Can also be used for hose‑to‑hose joining when both hose ends are fitted with appropriate grooved nipples.

For IMER contractors, this coupling ties IMER pumps and hoses into larger mechanical piping networks on site, without adapters that don’t match grooved standards.

Lightweight, Easy-to-Install Mechanical Coupling

A major advantage of the Imer 4" Mechanical Grooved Coupling is its ease of installation:

• The product description emphasizes “lightweight, easily installed connection.”

• The coupling is designed to slide quickly over grooved ends and tighten around them, typically using standard coupling bolts (consistent with mechanical coupling practices).

While the IMER listings do not spell out every material detail, similar 4" grooved flexible/mechanical couplings are usually made from ductile iron with a corrosion‑resistant finish and incorporate an EPDM gasket to ensure a pressure‑tight seal. These couplings:

• Allow quick assembly and disassembly with hand tools.

• Maintain alignment and seal against high internal pressures.

• Accommodate minor misalignment and vibration typical in pump and hose systems.

This makes the IMER 4" Mechanical GrovedCoupling a practical, job‑site‑ready solution for frequent hose and pipe changes.

How the Coupling Interfaces with Hose and Nipple

Contractors Direct adds an important detail about how the coupling integrates with hose:

• “The nipple slides easily into the hose and the clamp engages the nipple and around the hose O.D.”

Interpreting this with typical IMER setups:

• A grooved nipple or grooved‑end fitting is inserted into the end of the hose.

• The mechanical grooved coupling engages both the groove on the nipple and the outside of the hose, securing the connection.

• This creates a robust junction between hose and grooved piping or between two hoses with grooved nipples.

Such a configuration is common in mortar/fireproofing pumping systems, where IMER material hoses may need to connect directly to rigid grooved piping or manifolds.

IMER Use Cases: Pumps, Hoses, and Systems

The Imer 4" Mechanical GrovedCoupling is frequently used with IMER pumps and material‑handling equipment, such as:

• Mighty Small 50 / Step‑Up pumps – systems that pump mortar, fireproofing, or grout through hoses and sometimes into building piping.

• Screed and grout pumps – where IMER material hoses must connect to rigid distribution lines.

• High‑volume material transfer setups – where 4" hose is needed to move mixed material to multiple locations on a job.

The IMER Material Hose with Cam Couplings (used for mortar and fireproofing spray kits) can be integrated into broader piping layouts with grooved couplings like this one, giving contractors flexibility in system design.

OEM Part Number and Brand Alignment

For maintenance and ordering, the IMER OEM part number is important:

• IMER Model / SKU: 1107179.

Contractors Direct lists the product as:

• “Imer Victaulic 4" Coupler – Contractor Price – Brand: Imer | SKU: 1107179.”

Blades Direct and HandGearPro list it as:

• “Imer 4" Mechanical Groved Coupling, 1107179.”

This confirms you should reference 1107179 whenever you’re sourcing the correct OEM coupling for IMER systems rather than trying to mix and match generic couplings that may not fit your hose or nipples as expected.

Benefits of Using the Imer 4" Mechanical Grooved Coupling

Using the Imer 4" Mechanical GrovedCoupling offers several key benefits for IMER equipment users:

• Compatibility with IMER gear: It’s designed to match IMER hoses, nipples, and pump outlets, reducing fit issues and leaks.

• Integration with standard grooved piping: You can plug IMER hoses straight into existing mechanical pipe networks without special adapters.

• Fast assembly: Lightweight and easy to install, minimizing downtime when assembling or modifying pumping lines on site.

• Secure sealing and mechanical strength: The coupling is engineered to firmly clamp around the grooved nipple and hose O.D, providing a robust connection under pressure and vibration.

For contractors running IMER pump systems into building services, this coupling acts as the bridge between flexible IMER hoses and rigid grooved mechanical systems.
