What is shielded coupling?
Shielded couplings are engineered with a heavy-duty shear ring to handle the tensile stressing and shear forces that the pipeline contacts daily. When municipalities need to maintain pipe alignment, a shielded coupling is the obvious choice.
What is a hubless connector?
The No-Hub Coupling has a patented shield design that provides maximum transfer of pressure from the clamps to the gasket and pipe. Engineered to connect no-hub cast iron pipe in applications, replacing the less-efficient hub and spigot.
Can Fernco couplings be used above ground?
It is my understanding that flexible PVC couplings (e.g. Fernco) meet the definition of Mechanical Joint in the international residential code. The 2015 IRC prohibits the use of Mechanical Joints on PVC couplings above ground “unless otherwise approved”.
What are Fernco couplings used for?
Fernco pipe couplings and adapters are used for all types of in-house and sewer connections: drain, waste, vent piping, house-to-main, repairs, cut- ins, conductor, roof drains and increasers-reducers.
What is a banded coupling?
Flexseal shear banded couplings are specifically designed to connect and repair pipes on Water Authority (adopted) sewer and drainage applications. The shear band on this range of couplings gives the connection added protection against vertical shear loads that could cause the pipes to become mis-aligned.
What is no hub drain?
A No-Hub connection is achieved by butting No Hub soil pipe or plastic pipe to the bottom of the drain and securing it with a NO HUB coupling. Unless specified otherwise, all of MIFAB drains are shipped standard with No-Hub connections.
How much pressure can a Fernco hold?

What is a shielded transition coupling?
Shielded transition couplings are designed and manufactured to improve performance and pipe alignment in areas that require added shear strength for heavy loads. The shielded coupling is manufactured with a gasket, high-torque clamps, shear ring and coupling.
Why shielded couplings for underground pipelines?
Compaction, deflection and constant movement of underground infrastructure layers has forced many municipalities and contractors to make the change. Shielded couplings are engineered with a heavy-duty shear ring to handle the tensile stressing and shear forces that the pipeline contacts daily.
What performance codes do shielded couplings have to conform to?
Many shielded couplings are engineered to conform to performance codes for the user to easily understand the functionality and strength of the product. For example, Source One Environmental’s SilverBack XL conforms to CSA B602, ASTM D 5926 and ASTM C 1173.
Is an unshielded coupling a thing of the past?
The standard, unshielded coupling for underground applications is a thing of the past. And no, a coupling is not just a coupling. Compaction, deflection and constant movement of underground infrastructure layers has forced many municipalities and contractors to make the change.
