Coupling Configuration
Elastomer Sleeve
The flexible sealing sleeve fits around the adjoining pipe or fitting ends and provides the primary sealing surface at the connection.
Reinforced Shield
The stainless steel shield surrounds the sleeve and provides additional structural support and rigidity around the joint.
Multiple Clamp Bands
Multiple stainless steel clamp bands distribute tightening force around the coupling to help maintain alignment and secure the connection.
Construction Details
Midland Heavy-Duty No-Hub Couplings combine a resilient elastomer sleeve with reinforced stainless steel components to provide dependable sealing and mechanical support in cast iron DWV systems.
The stainless steel shield helps stabilize the joint while the multiple clamp bands distribute clamping force across the coupling for a secure connection.
This reinforced configuration is designed for applications requiring greater rigidity and holding strength than lighter-duty coupling designs.

Size Selection
Midland Heavy-Duty No-Hub Couplings are available in sizes from 1-1/2" through 10".
Select the coupling size that matches the compatible no-hub cast iron pipe or fitting ends being joined. Verify both connection sizes before ordering.
Installation Considerations
Ensure the pipe and fitting ends are clean, properly aligned, and fully seated within the elastomer sleeve before tightening the clamp bands.
All clamp bands should be tightened evenly and to the manufacturer's specified torque using an appropriate torque-controlled installation tool.
Our pipe and fitting specialists can help review your pipe size, cast iron DWV connection, coupling requirements, installation conditions, and project needs before you order.

What is a heavy-duty no-hub coupling?
It is a shielded mechanical coupling used to join compatible no-hub cast iron DWV pipe and fittings without a traditional hub-and-spigot connection.
What piping systems are these designed for?
The supplied product information identifies cast iron drain, waste, and vent (DWV) systems.
What sizes are available?
These couplings are available in sizes from 1-1/2" through 10".
What creates the seal?
A flexible elastomer sleeve fits around the adjoining pipe or fitting ends and provides the sealing surface.
What is the purpose of the stainless steel shield?
The reinforced shield provides additional structural support and helps maintain alignment around the joint.
Why are there multiple clamp bands?
Multiple bands distribute tightening force around the coupling and help provide increased holding strength and joint stability.
Do the clamp bands need to be tightened to a specific torque?
Yes. Tighten all bands to the manufacturer's recommended torque specification.
Can these be used for commercial plumbing?
Yes. The supplied product information identifies demanding commercial and industrial plumbing applications.
Should the pipe ends be cleaned before installation?
Yes. Clean and properly align the mating pipe or fitting ends before installing and tightening the coupling.
What should I verify before ordering?
Confirm pipe size, no-hub cast iron compatibility, installation requirements, coupling configuration, and applicable project or plumbing code requirements.
