What is a no hub coupling?
Intended for use with DWV systems, no-hub couplings are used to join cast iron soil pipe that does not have the traditional Hub and Spigot. They are normally installed using a torque wrench. Generally, they have more clamps and provide a greater band load than standard no-hub couplings.

What does no hub means?
What companies really mean when they say “no hub required” is that the device will connect to your WiFi network, then connect to the company’s servers over the internet. With this system, you are really just using someone else’s hub over the internet or “in the cloud” as many manufacturers like to say.
Can you use a no hub coupling underground?
Underground Installations Q: Can I use hubless cast iron soil pipe and fittings below ground, and is there anything special I need to do to protect the couplings? A: Hubless cast iron soil pipe and fittings are allowed for underground installations by all of the model codes.
Can you use a no hub coupling on PVC?
Even though no hub couplings were created especially for cast iron piping, they can be used to repair PVC and ABS piping too. PVC and ABS schedule 40 piping come with larger overall outer diameter compared to cast iron pipe. There is no drastic difference between this piping if we look at these diameters.
What does hub mean in plumbing?
As previously stated, the hub of the pipe is the female “bell” end of the pipe, which leaves the male end of the pipe the no-hub end. The no-hub connection option is probably the most used by nonprofessionals due to the ease of installation. All that is needed is a no-hub coupling to attach the drain to the pipe.
What does Hubless pipe mean?
Hubless pipe and fittings are also referred to in the plumbing industry as no-hub. Hubless cast iron soil pipe and fittings are manufactured without a hub, in compliance with CISPI 301. Hub and Spigot pipe and fittings have hubs into which the spigot (plain end) of the pipe or fitting is inserted.
Can I use a no hub coupling on PVC?
Although no-hub couplings were designed for cast iron they are also a very handy way to repair ABS or PVC. They can be especially helpful when the piping is in a hard to reach spot or the pipe is unable to be moved in either direction to allow the repair to be made with a solvent (glue-on) coupling.

Why do I need a hub?
A hub provides a common connection point for all devices in a network. It’s a central location for monitoring and managing all your electronic devices, so you can check and adjust everything according to your needs.
Are no-hub couplings code?
Q. No-hub rubber couplings with band clamps on the ends are handy for making all sorts of plumbing connections, but are there limitations on where they can be used? A. They’re accepted by a number of codes — including the Uniform Plumbing Code and the International Plumbing Code — for both above- and below-grade use.
Do Fernco fittings meet code?
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 is a no hub coupling used for?
No-hub couplings are commonly used to connect a grease trap to a no-hub cast iron pipe. They can also be used for soil waste, vent lines, and storm drainage applications. No-hub couplings have a shear-resistant metal sleeve, making for extremely durable fittings that can withstand waste and water flow for many years.
What are the ASTM C requirements for the heavy-duty MD couplings?
Couplings comply with ASTM C 1277. Gaskets are made from an elastomeric compound that meets the requirements of ASTM C 564. The distinctive yellow shield quickly identifies the Heavy-Duty MD Couplings and makes it easier for inspectors. 5/16″ hex-head screw applies 80 in.-lbs. of installation torque to the band/shield assembly.
How much torque do you need for a heavy duty coupling?
The distinctive yellow shield quickly identifies the Heavy-Duty MD Couplings and makes it easier for inspectors. 5/16″ hex-head screw applies 80 in.-lbs. of installation torque to the band/shield assembly. Couplings conform to CISPI 310, Factory Mutual CN 1680.
