Acme inlet threads have become the preferred thread configuration in the golf course irrigation market. An Acme thread has a flat apex and valley, and a wider tooth shape than an NPT thread. The wider tooth means it can withstand a greater load than a similarly sized square thread or NPT thread. An Acme thread also contains an O'ring to create a better seal. Hunter manufactures Acme Adapter Bushings in sizes ranging from 1 to 1 1/2 and multiple configurations are available to convert female and male NPT threads to ACME. Note: Acme threads are not compatible with NPT or BSP fittings.
The fire hose thread specifications for some local municipal fire equipment and hydrants may vary according to local specifications. These can generally be most easily identified by contacting the local fire department responsible for the hydrant. The most common thread used on fire equipment is National Standard Thread (NST), also known as National Hose thread (NH). When it is not possible to identify the thread: 1  Determine the number of threads per inch by measuring the distance from peak of thread to peak of thread across the largest number of whole threads. 2  Check to see if the thread is straight or tapered.
