Watts NH-BL-2-CPLG – Frequently Asked Questions
1) What is the Watts NH-BL-2-CPLG no hub coupling used for?
It joins 2 inch no hub (hubless) cast iron soil pipe and fittings. The coupling wraps the two plain pipe ends and clamps down over a gasket, so there is no bell, no lead and oakum, and no solvent weld involved. Watts sells it under the Blueline name as the NH-BL-2-CPLG.
2) Will a 2 inch no hub coupling work on PVC or copper DWV pipe?
Not as a like-for-like fitting. The NH-BL-2-CPLG is sized to 2 inch no hub cast iron outside diameters. Plastic and copper DWV in the same nominal size do not share that OD, so joining dissimilar material calls for a transition or shielded adapter coupling rated for that pairing rather than a standard no hub coupling.
3) Is the Watts NH-BL-2-CPLG Buy American Act compliant for a government job?
No. Watts lists the NH-BL-2-CPLG as not Buy American Act compliant, so it will not satisfy a BAA or Buy America procurement clause on a federal or federally funded project.
4) Do I need anything besides the coupling to make up a 2 inch no hub joint?
The coupling itself is the joint, gasket and clamp assembly for 2 inch no hub pipe. What you supply is the cut and deburred pipe ends and a torque wrench set to the clamp torque printed on the band, since no hub bands are torque sensitive and hand tightening is not a substitute.
5) What is the exact Watts part number to order for a 2 inch Blueline no hub coupling?
Order Watts part number NH-BL-2-CPLG. That is the manufacturer part number and the single model offered for the 2 inch Blueline no hub coupling.
