Gas Fittings – Why You Need a Licensed Gas Fitter


No matter, if it is for a new BBQ, heater, or fridge installation, professional licensed gas fitters, will ensure all appliances and piping work appropriately, conducting thorough safety inspections of their system of gas lines & piping systems.

Most common gas fittings feature a conical GAS thread that screws into an SAE nut on an end of a copper or brass pipe and creates an effective seal without using thread tape.


Gas fittings require specific knowledge and training in order to use correctly, in order to prevent leaks that could pose potential health and safety concerns. Therefore, having access to suitable fittings is of the utmost importance in order to use them correctly.

There is an assortment of gas fittings available, such as reducing, side outlet, and swivel versions, which can help make connections more flexible or allow for different configurations of your gas fire pit system. A licensed gas fitter will be able to advise on which kind will best meet the requirements for caravan or motorhome usage, as well as those compatible with specific appliances.

There are various options for gas pipe available today, with ProFlex CSST standing out among them as one suitable for residential use and offering multiple advantages over other forms of tubing, like more flexibility, easy bending around tight corners, and reduced corrosion risk.

Aluminum-Plastic Composite Pipe (APCP) is another choice, providing a solid but flexible gas pipeline. Furthermore, its lightweight design makes transport easy. Other gas fitting options include expansion joints, coupling connection sections, and insulated, lined, or plated fittings.


Gas pipelines must be constructed of durable material that can withstand high pressure, such as copper or steel piping materials. There are various options when selecting high-pressure piping materials; stainless steel may be the best choice due to its corrosion-resistance qualities and ability to hold up under strain.

PVC (polyvinyl chloride) plastic pipes offer another viable option for low-pressure piping applications, although its durability is lessened compared to metal options. When selecting PVC pipes from manufacturers, be wary unless they follow industry-standard manufacturing practices.

Aluminum-plastic composite pipe (APCP), which combines the durability of aluminum with plastic flexibility, is becoming an increasingly popular material choice for piping purposes.

Fittings that join a piping system are just as essential to its proper function as its pipes themselves. They must be strong enough to withstand pressure applied by the pipe system while sealing tight to prevent gas leakage. Wrought iron fittings tend to be stronger and less susceptible to leaking, making wrought iron an excellent choice.


Installing gas lines requires considering many different factors that could influence cost, with pipe materials like copper and steel having varying costs, as do fittings and supplies like thread sealant. Labor costs also play a factor; licensed professional gas fitters possess all of the knowledge and skills required to install a line correctly, safely, and code.

Gas line installations typically necessitate installing a shut-off valve near where the pipe enters your home, as well as one at each appliance connected to it. When selecting a replacement gas valve for use with gas appliances that is compatible with their connections,

Professional gas fitters must be employed when it comes to installing and replacing gas fittings, pipes, and appliances. To hire one for yourself, inquire as to their license number and certification – typically, plumbers carry both an Associate in Plumbing Certificate and separate gasfitter licenses.

Some homeowners try their hand at DIY home improvement projects. Although this can save money when it comes to installing or repairing gas pipes, the risks outweigh any savings that might be achieved through doing it themselves. By law, licensed professionals must comply with strict safety guidelines in order to safeguard homeowners’ health and well-being.


Many homeowners may be tempted to attempt DIY home repair projects themselves, including gas line maintenance. While this may seem appealing and potentially risk-free, experts possess training and have effective methods of maintaining gas lines safely. DIYers risk endangering themselves and their family’s lives if they attempt to undertake these tasks themselves.

Poor pipe connections are typically at the root of gas leaks, be they due to improper installation, an absence of tightness, or even age and wear. Homeowners will find it much simpler and faster to identify leaks early and fix them efficiently.

As soon as a gas leak is identified, it must be addressed immediately by switching off all appliances that use gas and calling a certified plumber for repairs. Most leaks occur where pipes meet at fittings (old shut-off valves, tees, unions, or flexible connectors); therefore, it is imperative that these connections are regularly examined to make sure that they are tight enough and leaks don’t occur in those locations.

Teflon tape should never be used on gas line connections as this type of tape was meant for water pipe threads and may cause leakage when used on gas fittings. Instead, look for special yellow Teflon tape designed specifically for gas connections, which is available from hardware, home improvement, and plumbing supply stores.
