Ward 15c.wf250 Csst Gas Piping 1/2 Inch 250 Foot Coil

Product Description

The WARD 15c.wf250 is a 250-foot coil of 1/2-inch nominal corrugated stainless steel tubing (CSST) designed for flexible gas piping in residential and commercial buildings. Constructed from 304 stainless steel to ASTM A240 specification, this is the Wardflex II system, engineered with a conductive coating that disperses electrical energy induced on the tubing when arcing occurs between CSST and another metallic system — a key mitigation feature against lightning-induced transient energy. The tubing carries a 25 psi pressure rating and is 100 percent leak tested at the factory before shipment. Licensed plumbers and gas fitters are the primary installers of this product.

The 15c.wf250 is suited for natural gas and LP gas distribution within residential and light commercial structures. Its flexible corrugated design allows routing through walls, floors, and framing with fewer fittings than rigid pipe, reducing both labor time and potential leak points. The polyethylene jacket includes UV inhibitors, making it appropriate for installations in areas with incidental UV exposure. The conductive coating is marked every 2 inches along the length to aid in field identification and proper bonding compliance during inspection.

Key Features

• Conductive coating disperses lightning-induced electrical energy to reduce risk of arcing damage between CSST and adjacent metallic systems
• 100 percent factory leak tested prior to packaging
• Coating marked every 2 inches for easy field identification and bonding verification
• Polyethylene jacket with UV inhibitors for durability in varied installation environments
• Flexible corrugated design reduces fitting count and speeds installation versus rigid pipe
• Meets ANSI LC-1, CSA 6.26, UL, FM, IAPMO, and ICC standards; jacket is ASTM E84 compliant

Compatibility

Designed for use with the Wardflex II CSST gas piping system in residential and commercial natural gas and LP gas distribution applications. Compatible fittings and termination components must be specified as part of the Wardflex II system per manufacturer installation guidelines.

Installation Notes

Installation must be performed by a licensed plumber or gas fitter in accordance with local codes, IFGC requirements, and the manufacturer's listed installation instructions. Shut off the gas supply and verify zero pressure at the work area before making any connections. CSST systems require bonding and grounding per applicable electrical and gas codes — verify local amendment requirements before roughing in. Do not kink or compress the corrugated tubing during bending; use a tubing bender or follow minimum bend-radius guidance from the manufacturer.
