Use the Proper Cylinder and Fittings for the Job.

Connections of Propane Cylinders -
Manufactured Before 1994

Before 1994, cylinder valves had a left hand thread for connection to appliances. The left-hand threaded fitting that connects to the cylinder valve has to be turned to the left (counter-clock wise) to tighten. Some older connectors have a hand wheel requiring only hand tightening, some require a wrench to tighten and some have an "O" ring. Always ensure that the rubber "O" ring on these traditional fittings is in good condition and in place before connecting to the cylinder valve. The "O" ring is a small rubber-like washer that fits into a groove in front of the threads. Double-check this connection when you are doing your "soap and water" leak test (see below). Repair a damaged or cracked "O" ring with a new one, which may be obtained from Sparling's Propane or a retailer near you. For this type of connection, use a proper fitting wrench (do not use pliers) to tighten the threaded connection between the regulator and the cylinder valve. Whenever a cylinder is not connected for use, a special plug or cap should always be installed on the outlet of the cylinder valve. This plug is designed to prevent a leak of propane should the valve be accidentally turned on.

Connections on Propane Cylinders -
Manufactured Since 1994

Since 1994, barbecue cylinder connections have been redesigned and will either be a right-hand thread plastic nut connector or a quick disconnect device. The new type connections are interchangeable with each other. These new connection types are equipped with an internal device designed to prevent the flow of propane unless the valve is connected to the appliance. The cap or plug provided by the manufacturer should be installed on the valve outlet whenever the cylinder is not connected for use to protect the valve from dust and other foreign matter. Do not use the old style left hand thread plug with these new connections as a propane leak could result. Ensure all connections are leak tight before operating your propane appliance.

The following Safety Rules apply to the Safe Handling of Propane Cylinders:

• Ensure the cylinder is secured in place.
• Always keep a cylinder upright.
• Never put a propane cylinder in an enclosed vehicle.
• When transporting, secure the cylinder in an upright position to prevent tipping. If transporting in a trunk, block the trunk lid open.
• Cylinders are painted in light-reflecting colours (i.e. white, tan).
• If you must repaint your cylinder do not use a colour which absorbs heat (i.e. black, dark green). This could cause the propane liquid to expand and be released through the safety valve.
• Never take a propane cylinder indoors if it contains, or has contained, propane. This is dangerous and unlawful.
• When purchasing a new cylinder, be sure that it is the size that fits your appliance bracket and the cylinder valve connection is compatible with the connection type on your barbecue or appliances.
• Check that the cylinder valve is closed whenever the cylinder is not in use and before connecting or disconnecting the cylinder.
• Check that all valves on appliances are closed before connecting a cylinder.
