What is a no hub coupling used for?
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.
How much pressure can a no hub coupling hold?
The Anaco standard no-hub couplings conform to CISPI 310 & ASTM C 1277. The specified test pressure in the standards are 20 psi for 1 ½” – 5”, 18 psi for 6”, 10 psi for 8”, 6 psi for 10”, 12” and 15”.
What does no hub connection mean?
NO-HUB (NH) (A/K/A Mechanical Joint) The most widely used connection. 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.
How long will a Fernco last?
It should last a very long time. Don’t worry about it. I agree one hundred percent… It is a petroleum product and will likely turn back into a fossil fuel in, oh, about 10,000 years…
What is a hub drain used for?
Designed to fit with trench drains, floor sinks, sanitary drains, and catch basins.
Can you bury a no hub coupling?
Mission and husky couplings are allowed underground here, no hubs aswell. Have to fasten to 60ibs.
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. For these two smaller sizes you could use a no-hub coupling to connect ABS or PVC directly to cast iron piping without a problem.
What is hub fitting?
Hub – a type of DWV fitting end that allows pipe to slide into the end. This standard allows NPT threaded fittings to fit together in a water-tight seal.
Are Fernco couplings legal?
Fernco (Rubber) fittings are not approved in wall framing unless they have a metal sheathed hose clamp assembly covering the entire fitting as part of the design, Which limit them to straight couplings or reducing couplings. The reason is that vermin can chew through the rubber.
What can a no hub coupling be used for?
A no-hub coupling joins two hub-less connections. 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.
What’s the best way to glue a slip coupling?
Spend 30 seconds removing burrs (you don’t want waste like hair and food catching on them). Apply pipe cleaner. Apply the glue all the way around in a quick swirl on each half, no finesse required. Slip the coupling up the pipe. Done.
What are no hub couplings for cast iron gasket?
Engineered to connect no-hub cast iron pipe. 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.
How much torque does a no hub screw apply?
Standard No-Hub 5/16″ hex-head screw applies 60 in.-lbs. of installation torque to the band/shield assembly. Standard No-Hub Couplings conform to CISPI 310. Couplings comply with ASTM C 1277.
