Asc Engineered Solutions 20A.WF50 Csst Gas Tubing 3/4in 50ft

Product Description

The ASC Engineered Solutions 20A.WF50 is a corrugated stainless steel tubing (CSST) product used for flexible gas piping installations in residential and light commercial construction. Manufactured from 304 stainless steel with a black jacket, this tubing measures 3/4 inch in diameter and comes in a 50-foot length. It meets a broad set of code requirements including ANSI LC1, ASTM A240/E84, CSA 112940, IAPMO 3353, ICC ESR-1879, and UL R18357. The domestic origin and multi-standard certification make it a code-compliant choice for natural gas and propane distribution systems.

This CSST is suited for gas distribution runs inside walls, floors, and mechanical spaces in residential homes and light commercial buildings. It is designed to replace rigid black iron pipe runs in applications where flexibility and faster installation are priorities. Plumbers and gas fitters use this product when routing gas lines from the meter or manifold to appliances such as furnaces, water heaters, ranges, and dryers. The 50-foot coil length accommodates longer runs without field splicing.

Installation Notes

CSST installation must be performed by a licensed plumber or gas fitter in accordance with local codes and the manufacturer installation instructions, which reference ANSI LC1 and applicable fuel gas codes such as the IFGC and NFPA 54. Shut off the gas supply and verify zero pressure before making any connections.
