What are no-hub couplings for?

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.

What is a no hub adapter?

The NIBCO 3 in. PVC DWV Soil Pipe Hub x No Hub Adapter is used in a non-pressurized sanitary system which removes water-borne waste from plumbing and appliances. It adapts PVC piping to cast iron using cement and clamp or rubber sleeve.

Can you use a no hub coupling underground?

Cast-Iron No-Hub Pipe is safe for underground use and ideal for DWV soil-drain applications. This durable pipe can endure temperatures up to 212 degrees Fahrenheit.

Can you bury a no hub coupling?

Mission and husky couplings are allowed underground here, no hubs aswell. Have to fasten to 60ibs.

Can you use no hub bands on PVC pipe?

Even though no hub couplings were created especially for cast iron piping, they can be used to repair PVC and ABS piping too.

How big is a no hub coupling screw?

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.

What are no hub couplings for cast iron?

No-Hub Couplings. 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 did no hub couplings change the world?

No-hub couplings revolutionized cast iron drainage pipe installations from a hazardous, tedious, skilled craftsman trade, to a simpler, quicker, less tools needed, safer occupation.

Can a no hub coupling be used with ABS?

One side glues over ABS or PVC and the other side is the same size as no-hub cast iron pipe. Without the use of these special adapters, the inner gasket of a no-hub coupling will stretch too much and not provide the best seal possible.

What kind of wrench to use for no hub couplings?

They are normally installed using a torque wrench. 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.

What is the cispi standard for no hub couplings?

No-Hub Couplings. Standard Couplings. CISPI Standard 310: Specification for coupling for use in connection with hubless cast iron pipe and fittings for sanitary and storm drain, waste, and vent piping application (Regular hubless coupling)

Can a no hub coupling be used on a DWV?

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.
