The threads do not make the seal, they merely hold the two fittings tightly together.

What is NH coupling?

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.

What is GHT and NPT?

Garden hose threads and national pipe tapers are completely different screw threads. GHT has parallel threads, while NPT has tapered threads. GHTs are for gardening and landscaping use while NPTs are for plumbing systems. Both threads do not fit each other, so you cannot use them together in one joint.
