I was perusing the wares at TSC, browsing amid the various hydraulic hose fittings, when I happened upon a variation in fittings that I do not comprehend.
Please have a look.
Standard male pipe thread :
Swivel Adapter, 3/8 in. Male Pipe x 3/8 in. Female Pipe Swivel - 1818503 | Tractor Supply Company
Restricted male pipe thread :
Swivel Adapter, 3/8 in. Restricted Male Pipe x 3/8 in. Female Pipe Swivel - 1818147 | Tractor Supply Company
To my eye, they both appear the same.
What makes a male pipe thread "restricted" and how would one recognize which he had on any random hose assembly ??
I have been messing with NPT all of my life and never before knew such an animal existed.
Thanks.
