Most Frequently Asked Questions

quality stainless steel? "You say 5/8" o.d. flare (15/16" - 16 thread). What does that mean?"
top quality stainless gas flexes The 15/16" refers to the size, and 16 thread refers to the number of threads per inch. This specific size and thread pitch is required for GSA design certification of 5/8" od appliance connectors.

quality stainless steel? "I need a flexible gas connector that is exactly 18-inches long. Will your 18" gas flex work?"
top quality stainless gas flexes It may, but it would best to buy a 24-inch gas flex to allow for slack in the line and prevent the possibility of stressing the gas flex.

quality stainless steel? "I need to connect my propane tank to the regulator. Will these gas flexes work for that purpose?"
top quality stainless gas flexes No, these gas flexes are for "low" pressure connections only.

gas connectors? "I've heard that gas connectors need to be changed every ten years or less for safety. Is there any truth in that?"
gas related No, the stainless connectors that we sell will generally last as long as your house (if not repeatedly moved or physically damaged). Sometimes older, non stainless steel, coated or uncoated budget gas connectors can be a real safety hazard. Some older, uncoated brass connectors have a serious flaw that can, over time, cause a leak, fire or explosion. These uncoated brass connectors have not been made for more than 20 years but are still in use and sometimes are sold at garage sales, etc. The older these connectors get, the greater the possibility of failure.

Appliance connectors have been used for years, because they are made of corrugated piping and can be shaped to fit in spaces between your appliances and gas piping. But these connectors aren't made to last a lifetime, nor are they made to withstand the stress put on them when appliances are moved frequently. Although not all uncoated connectors have this flaw, it's very difficult to tell which ones do.

We believe that any uncoated brass connector should be replaced immediately with one of our new stainless steel connectors. Replace any connectors that appears corroded or appears brittle. Check occasionally for gas odor. If you smell gas, make sure all pilot lights are lit. If the odor persists or if you hear gas leaking, close the appliance shut-off valve, but only if you can do this without moving the appliance or connector. Evacuate everyone from the house immediately, opening windows and doors as you go. Do not use your telephone, operate any gas or electric appliances, or turn light switches on or off. Sparks from any of these could ignite the gas.

Code requires that a new gas appliance connector must be used for a new appliance, when moving an appliance to a new location, or as a result of damage (ANSI Z21.24/CSA 6.10 and ANSI Z21.75/CSA 6.27). It is a good idea to always install a new gas connector when you replace an appliance. Again, we highly recommend that you immediately replace any uncoated brass connectors with a quality stainless steel or brand new, coated connector.

For safety, only use one connector for each appliance. Never use two connectors together to extend the length.
