Home 9 Residential LPG Blogs 9 A Quick Guide on your Gas Bayonet Fitting

30 Aug, 2023 | Residential LPG Blogs

In this article:

A gas bayonet is a wall-mounted LPG gas outlet that supplies LPG to many appliances, such as gas heaters, without needing an additional gas bottle. It works similarly to power supply wall sockets that distribute electricity to certain points—but for an LPG. The bayonet outlet is plumbed into the gas supply from your existing LPG bottle via the gas pipe. It is low-pressure, making LPG safe to use for homes and businesses and is useful when removing gas appliances.

Gas appliance bayonet fitting – How it works

A female gas bayonet fitting can be floor or wall-mounted. These BSP thread fittings provide a quick connection from the gas supply to disconnect gas appliances safely. Using LPG or natural gas to fuel gas appliances, such as a portable gas bayonet heater, is generally more economical than resistant electric heating.

Popular gas heaters in Australia include gas appliances such as the Rinnai Avenger. Portable gas heaters with bayonet fittings are also used in camper vans, motorhomes, and holiday homes.

In summary:

  • A male gas bayonet hose fitting can connect your gas appliance, such as a gas bayonet heater, to a fixed female gas bayonet wall socket fitting attached to the gas supply.
  • The male gas heater bayonet fitting is attached to the end of the gas bayonet braided hose.
  • The female gas bayonet wall socket fitting is connected to the gas supply line and is affixed to the wall or floor.
  • A male gas bayonet hose makes the gas bayonet fitting connection by pushing in and twisting clockwise to lock it in place.
  • To remove the gas bayonet fitting, you push in slightly, turn anti-clockwise, and then pull the male gas bayonet fitting out.

Female Gas Supply Bayonet Wall Socket Fitting

The female gas bayonet wall socket fitting is permanently attached to your wall or floor socket, and the supply gas line is connected to it through the wall or floor. The bayonet fitting has locking lugs allowing quick installation and safe removal. It also contains the on/off gas shut-off valve that is automatically actuated when a male gas bayonet fitting is fully inserted and locked. A rubber O-ring seals the gas heater bayonet connection fitting.

Male Gas Bayonet Fitting

The male bayonet fitting is affixed to the end of the stainless steel braided bayonet hose attached to the gas heater or gas appliance. It has two push-and-twist slots to engage the two locking lugs on the female gas bayonet wall socket fitting.

Male bayonet fittings also have a protrusion that pushes on and opens the automatic gas valve when the male gas bayonet fitting is inserted and interlinked. The on/off gas valve is shut off when the male fitting is disconnected from the gas appliances, as these same protrusions disengage the automatic gas valve and close the gas line connection.

Gas Pipe Bayonet Fitting Installation

A licensed gas fitter must always install the gas bayonet fitting. The female gas bayonet fitting is installed through a wall or the floor and is connected to the gas bottle piping. Hence, it involves significant plumbing work, which should only be performed by certified professionals.

The male gas bayonet fitting installation is just a matter of attaching it to the end of a gas bayonet hose, typically done by the hose manufacturer. Various components may be required to properly connect gas cookers or heaters to the bayonet fittings, including:

  • Bayonet hose
  • Bayonet socket: angled or straight in brass, chrome or stainless steel
  • Bayonet adaptor (male)
  • Bayonet fitting (male)
  • Wall bayonet
  • Mounting bracket

Inspect & Clean Gas Appliance Bayonet Fittings

Before connecting gas bayonet fittings, they must be clean and free of dirt or debris. Grit or debris can result in an inadequate connection and cause the gas heater bayonet fitting to leak. You should periodically inspect the gas bayonet hose for damage or degradation. Call your gas fitter to make any needed repairs.

Guide on How to Disconnect LPG Appliance Bayonet Fitting

To disconnect a gas heater bayonet fitting:

  1. Carefully move the gas appliance away from the wall to access the brass fittings easily.
  2. Reverse the process used to connect the appliance to the fitting. Slowly press the male fitting slightly.
  3. Then, turn it anti-clockwise to disengage the locking lugs.
  4. Pull the male fitting out.

There may be a small whiff of gas during gas bayonet fitting removal. This is normal, as there may be a small residual gas in the gas hose supply line.

If You Continue to Smell Gas

If you continue to smell gas or detect a continuous or ongoing leak, you should turn off the gas and disconnect the gas heater. If you have an ongoing problem, you should always call your gas fitter. Never attempt your own gas repairs or allow an unqualified person to try to fix it for you.
