Conversion Gas Fitting Changes LP Tank Attachment from POL to QCC

Gas fittings -- available here -- are always needed as we repair and install various barbecues and gas appliances in custom outdoor kitchens. This adaptor is usually useful for barbecues in south America and the Carribean Islands because the rules in the US that added all the LP cylinder safety features has not been strictly enforrced elsewhere. However, as people change to new regulators the new regulators have standardized the thick-thread QCC connection and it becomes necessary to either change the LP tank or adapt the fitting on the valve.

Propane Tank Connect

Propane cylinders available for residential use today are manufactured with safety features mandated by federal laws to keep propane use safe. Since these rules went into affect the connection on propane cylinders has mostly standardized to the QCC connection that has thick threads on the outside of the LP tank valve. Newer regulators that used to have several different types of connections almost all have QCC handwheels on them now to fit to these thick external threads on the newer tanks.

Adding this adapter allows a new style regulator with this handwheel to attcah to an older LP tank. However, many old tanks do not have the safety features built into the valve.

QCC Handwheel

This QCC handwheel has become the standard for regulators but in some places the LP tanks do not have the external thick threads that fit this handwheel. For the older style of LP tanks that use the inner threads on the propane tank this conversion will thread into the LP tanks inner threads leaving the thick QCC threads sticking out.

The adaptor comes with the black plastic break-away tool attached so it can be threaded into the reverse threads of the propane cylinder valve. As we tighten the adapter into the propane tank the plastic grip will unscrew from the inner threads of the adaptor. Once installed the LP tank can now be used either either the newer QCC handwheel or the inner thread POL attachment.

As shown in thiss drawing from the user manual the adapter screws into the inside thread of the new liquid propane cylinder in order to change the fitting style to fit the new kind of handwheel on the hose and regulator on most barbecues.

male quick connect

This is the male quick connect adapter that works with the older LP tanks that used pneumatic connections on the regulator.

Many older grills used a pneumatic fitting like an air hose. This is normally called a quick-connect because the hose connection pops on and off by sliding back the connection sleeve. This connection also threads into the inner threads of the propane tank but the quick connect female side is left sticking out so the tank can be used as a quick connect even with the safety features.
