Jones Stephens expands its product offering of large 1” OD yellow-coated gas connectors. This expansion strengthens the category, which already includes 3/8” OD, 5/8” OD and 1/2” OD sizes, the company points out. All gas connectors, including yellow-coated, black-coated and uncoated, are available in 12” to 72” lengths. Comprised of stainless steel 304 material and 100% leak tested. The yellow-coated corrugation extends all the way to the fitting for increased tubing flexibility, and the flared-end fittings create a metal-to-metal seal, making for a high-quality product, the company says. Jones Stephens gas connectors are CSA design certified. Jones Stephens.
