Asc Engineered Solutions 32A.WF50 Csst Gas Tubing 1-1/4 in 50 Ft

Product Description

The ASC Engineered Solutions 32A.WF50 is a corrugated stainless steel tubing (CSST) assembly used for flexible gas piping in residential and commercial construction. Manufactured from 304 stainless steel with a black jacket, this 50-foot length is designed to route natural gas or propane from a meter or manifold to appliances and equipment. It carries certifications from ANSI LC1, ASTM A240/E84, CSA 6.26, IAPMO, ICC, and UL, confirming compliance with major fuel-gas and building code standards. Licensed plumbers and gas fitters rely on CSST to reduce fitting count and navigate through framing more efficiently than rigid black iron pipe.

This tubing is suited for new construction and retrofit gas piping installations in residential and light commercial buildings. The 50-foot coil provides enough length for most single-appliance runs or multi-drop manifold systems. The black polymer jacket provides mechanical protection and UV resistance. It is appropriate for natural gas and LP gas service where CSST is permitted by the authority having jurisdiction.

Key Features

• 304 stainless steel corrugated construction for flexibility and corrosion resistance
• Black jacket for mechanical protection and visual identification
• 50-foot coil length reduces the need for mid-run joints
• 1-1/4 inch nominal size for higher-capacity gas appliance runs
• Meets ANSI LC1, ASTM A240/E84, CSA, IAPMO, ICC ESR-1879, and UL listing requirements
• Domestic manufacture

Compatibility

Designed for use with compatible CSST fittings and manifold systems approved for natural gas and LP gas service in residential and commercial gas piping applications. Consult the manufacturer installation guide and local code authority to confirm fitting and termination compatibility.

Installation Notes

CSST installation must be performed by a licensed plumber or gas fitter in accordance with IFGC requirements and the authority having jurisdiction. Shut off the gas supply and verify zero pressure before cutting or connecting tubing. Bonding and grounding of CSST is required per IFGC and local amendments — confirm requirements before installation. Avoid kinking or over-bending; follow the manufacturer minimum bend radius specified in the installation guide.
