Watts NH-BL-3-CPLG – Frequently Asked Questions
1) What pipe size does the Watts NH-BL-3-CPLG no-hub coupling fit?
It's a 3 inch no-hub coupling from the Watts Blueline range, so it joins 3 inch no-hub (hubless) cast iron pipe and fittings. Order it by part number NH-BL-3-CPLG.
2) Can I use a no-hub coupling like the Watts NH-BL-3-CPLG on plain-end plastic DWV pipe, or only on cast iron?
A no-hub coupling is made to band two plain-end hubless pipe ends together, and the Watts NH-BL-3-CPLG is the 3 inch size. For a cast iron to plastic transition on 3 inch DWV, a plain-end-to-plain-end no-hub band is the usual approach, but confirm the outside diameters match before you tighten it down, since cast iron and plastic 3 inch OD are not identical.
3) Do I need anything else to install the Watts NH-BL-3-CPLG, or is it ready to go?
The 3 inch Blueline no-hub coupling is a shielded band coupling, so the only tool you need on site is a torque wrench or no-hub driver to set the clamp screws. No solvent, no gasket lube, no separate sleeve to buy.
