Custom Gas Supply Lines

Bent, Fabricated & Assembled to Your Specs

Tubular gas supply lines are key components in a wide range of devices and equipment, from propane fireplaces and barbecue grills to air conditioners and natural gas-fired water heaters. These gas supply lines require high precision, close-tolerance bending and forming to guarantee a proper fit in the larger system, along with fittings, special weldments, and more to ensure safety and reliable performance. To maximize longevity and corrosion resistance, the tube material must be properly matched to the media being transferred.

As the equipment and machinery that they’re used in can vary greatly in size, shape, and performance requirements (two air conditioner models made by the same OEM can have wildly different configurations, for example), there’s no such thing as a “standard” gas supply line. Each different device requires a specially designed and fabricated solution.
