Natural Gas

Natural Gas/Propane

The Chicago Fittings product line provides a wide variety of transition fittings for the natural gas and propane markets. This includes risers, adapters, couplings, and numerous specialty items. We put a heavy emphasis on eliminating below grade joints in your system wherever possible, evident in the ever popular X-Riser®.

Sealastic Design

Sealastic Design

The Chicago Fittings product line includes a sealastic design that offers a quick, reliable mechanical joint. Sealastic Fittings are particularly suited to automotive and heavy equipment applications where vibration, high speeds, and mechanical shock are encountered. Installation is quick and easy as no special tube preparation is required.

X-Riser

X-Riser®

The Chicago Fittings X-Riser® removes a minimum of two below grade joints per riser when compared to that of a standard pigtail style anodeless riser. In addition, those joints buried below ground are now moved to a single above grade joint, eliminating the risks and liabilities associated with below grade joints.
