Components of the Large-Bore System
1. There are two basic spud designs:
a. The standard clamp-in spud (VHJSP2)
b. The screw-in spud
2. Into one of these spuds you screw a Large Bore Swivel Valve. While
all Large Bore Valves vary in bend, length, and appearance, they all have a
swivel feature (VHJ650). An O-ringseals into the valve spud and is tightened down with a
swivel nut.
3. To service the inside dual there are three types of extensions offered:
a. A rigid extension
b. A hand-bendable extension
c. A flexible extension
