Various legal issues arise concerning the use and distribution of gas.


A Municipal Corporation does not have the duty to supply gas to its population. In the event that a city assumes the performance of such function, it is acting merely as a business corporation.

The charter of a gas company is a franchise granted by the state. The manufacture of distribution of gas for light, fuel, or power is a business of a public character, and, therefore, a gas company is ordinarily considered to be a public or quasi-public corporation or a business affected with a public interest. A state may regulate gas companies for the protection of the public and may delegate its regulatory powers to municipal corporations in which gas companies operate. In a number of states, gas companies are subject to a public service commission or other such agency. The jurisdiction of the commission ordinarily includes the power to establish rates and to set forth rules and regulations affecting the service, operation, management, and conduct of the business.

Consumer Supply

Upon obtaining a franchise to supply gas to a particular geographic area, a gas company is bound to fulfill its obligation; it cannot withdraw its service from an area merely because it is dissatisfied with the rates permitted there. Once the franchise of a company has expired, it may withdraw the service. A court may, in certain instances, enjoin the discontinuance of service for a reasonable period—to circumvent undue hardship and inconvenience to the residents of the area.

A gas company has the duty to serve all those who are within the franchise area who desire service and subscribe to the reasonable rules that it may set forth. A municipality or corporation supplying gas may make reasonable rules and regulations to secure the payment of bills, such as eliminating service to the consumer. If there is a genuine controversy about the amount owed, a company is not permitted to discontinue service. A gas company may not require the owner or occupant of a building to pay over-due and unpaid bills by a former owner or occupant before it continues service to the building. Some statutes require that gas companies install a meter on the premises, in order to register the consumption of gas by each customer; and where a customer tampers with the meter and uses a significant amount of unmetered gas, the company can discontinue service and refuse to restore it until the customer pays the amount due for the unmetered gas taken.

A gas company that wrongfully refuses to supply a customer with gas is liable for damages. There are also statutory penalties in some states for such wrongful refusal.


A gas company is under the obligation to exercise ordinary care in the construction of its works and the conduct of its business in order to protect life and property.

Gas has a highly dangerous and volatile character and tends to escape. A gas company must, therefore, exercise care to avoid harm to others and is liable for its Negligence that results in injury to others by reason of the escape or explosion of gas. It must exercise reasonable care in the inspection of its pipes to ensure that leaks may be discovered promptly; and if leaks or defects in the pipes of the company occur due to faulty construction or maintenance, the company is liable for resulting injuries, even though it did not know about the leak.

In the event that the company has taken due care in the inspection of its pipes and a defect or a break occurs through natural causes or by the act of a third person, the gas company must be given notice of the defect and reasonable time to repair it before liability accrues. A gas company subject to notice that gas is escaping is under an obligation to shut off the gas supply until the necessary repairs have been made.

A gas company has a property right in the mains and pipes and other appliances, and where there is unauthorized interference with, or damage to, this property, the company is entitled to recover damages and an Injunction if the circumstances so warrant.


A gas company has a legal obligation to charge reasonable rates. One of the main purposes of the regulation of gas companies is to prescribe fair and reasonable rates for the selling of gas to the public. Rate increases are permitted only following an impartial and complete investigation—with the object of doing justice to the gas company as well as the public. Relief can be sought in the courts if gas rates are unreasonable—to determine whether the rate making body acted beyond the scope of its power or against the weight of the evidence. The courts, however, cannot decide what rates are reasonable, nor can they put those rates into effect.

When the results of the micro-ESR methods measured in sedimentation hematocrit were compared to the Westergren results also measured in sedimentation hematocrit, the following correlation coefficients were obtained: the micro-hematocrit tube was 0.653, the S/P capillary blood gas tube was 0.806, the Natelson blood collecting tube was 0.719, and the Caraway micro blood collecting tube was 0.797.
The gas piston is also stainless steel and fits into the gas tube with only about .001" clearance.
If that gas tube moves when the bolt carrier comes forward, the carrier key is hitting the gas tube.
This may not happen with some of the larger pins, but something like an ejector or gas tube pin can usually be reused without worries.
The gas tube must be shortened to fit the short barrel.
Allcom Products, located in South Elgin IL, specializes in the manufacture of short-run prototyes to full production runs and distribution of quality coaxial cable assemblies, SG and SGD Series gas tube and SF Series filter design coaxial lightning suppression devices; SCP6W, STPV and STPT Series ac/dc MOV/gas tube impulse suppression products; wiring harnesses and coaxial and wire pigtails.
I would suggest before repairers replace the carrier key or bolt carrier assembly that they first check for a bent gas tube. Follow these steps:
The gas tube is enclosed and vented, and a Hogue OverMolded pistol grip is used.
This will expose the barrel, barrel nut, gas tube, and gas block.
Very closely related to the previous topic of carrier positioning is the subject of gas tube alignment.
In Ecklund's design, gas is tapped off through a port and carried through a stainless steel gas tube to a blind cup on the face of the bolt carrier.
