Standard 1-1/8" ORB thread fits every standard CNG cylinder on the market besides 1" BS341 (British Standard Tapered thread), older NGT cylinders, or cylinders with a 2" diameter valve connection.
Comes with 2 -6(9/16")F ORB ports and American CNG's proprietary defueling port. Our defueling port valve works perfectly with our Cylinder Pressure Testing Tool to both safely defuel a cylinder or test the current pressure in a cylinder.
