Watts MJ CR CLS 1/2 – Frequently Asked Questions
1) Is the Watts MJ CR CLS 1/2 coupling Buy American Act compliant for a federal job?
No. The MJ CR CLS 1/2 no-hub coupling is not Buy American Act compliant, so it will not satisfy a BAA or federally funded procurement spec that requires domestic content. On those jobs you need a coupling carrying a BAA compliance statement.
2) Do I need solvent cement or a torch to install a no-hub coupling like the Watts MJ CR CLS 1/2?
No. A no-hub coupling is a mechanical joint: the elastomeric sleeve slips over the plain pipe ends and a clamped shield band is tightened down with a torque wrench or nut driver. No lead and oakum, no solvent cement, no flame. That is why hubless cast iron gets used in occupied and retrofit spaces where hot work is restricted.
3) What part number should I order for the Watts 1-1/2 inch Plenum Plus coupling?
Order Watts part number MJ CR CLS 1/2. That is the manufacturer designation for the 1-1/2 inch Plenum Plus no-hub coupling, and it is the number to quote so you do not get shipped an adjacent size.
4) Can a no-hub coupling be used to join two plain-end cast iron pipes with no hubs on either side?
Yes, that is exactly what it does. The 1-1/2 inch MJ CR CLS 1/2 wraps a plain pipe end on each side and clamps down, so it couples two hubless ends, or a cut piece back into an existing hubless line. If your existing pipe has a bell hub, you are not making that joint with this coupling.
