LP Type I (QCC) Connectors
Type I (QCC) connectors are designed with a built-in
excess flow feature and a positive shut off that will not allow
gas to flow until the connector is fully engaged. In the case of a
fire the built in thermoal protection on a QCC connector melts,
allowing the nipple to disengage at the tank connection and
stop the flow of propane. The QCC connector also provides
a positive check valve or back check seal at deisconnet, eliminating
propane in the hose from being released into the atmosphere.
NOTE: TYPE I (QCC) thread replaces the POL
connection on 40 pound of less DOT propane cylinders.
Warning:
An excess flow valve will NOT activate if there is a break or leak
downstream of the valve that does not equal or exceed the closing
flow of the valve or if the excess flow valve installed exceeds the flow capacity of
the system.
