Matco-Norca offers no hub couplings in both standard and heavy-duty versions for use in joining hubless cast iron pipe applications. Both Standard and Heavy-Duty Couplings provide ease of installation and permanent sealing solutions as well as proper pipe alignment.

Sizes 1-1/2” – 4” contain two Type 310 stainless steel bands standard (with 4 bands available upon request); sizes 5”-10” come with 4 bands standard (with 6 bands available upon request).
452 Series Standard No Hub Couplings come with a neoprene gasket to provide a cushioning element in the joint to absorb shock and vibration, assuring a quiet, trouble-fee operating plumbing system.
