Asc Engineered Solutions 20A.WF100 Csst Tubing 3/4in 100ft

Product Description

The ASC Engineered Solutions 20A.WF100 is a corrugated stainless steel tubing (CSST) assembly used for flexible gas piping in residential and light commercial construction. Manufactured from 304 stainless steel with a black polymer jacket, this tubing measures 0.75 inches in diameter and comes in a 100-foot length. It is designed to distribute natural gas or LP gas from a meter or manifold to appliances throughout a structure. Licensed plumbers, pipefitters, and gas installation contractors install this product in accordance with applicable fuel gas codes. The black jacket color aids in field identification and differentiates it from other utility lines.

This CSST is suited for new construction and retrofit gas distribution systems in residential and light commercial applications. The flexible design allows routing through walls, floors, and framing without the rigid fitting count required by black iron pipe systems. The 100-foot coil length supports long runs from a central manifold to multiple appliances including furnaces, water heaters, ranges, and dryers. It carries listings under ANSI LC1, ASTM A240/E84, CSA 112940, IAPMO 3353, ICC ESR-1879, and UL R18357, confirming compliance with major model codes and standards in the United States and Canada.

Compatibility

Designed for use in flexible gas piping systems distributing natural gas or liquid propane in residential and light commercial installations where 0.75-inch CSST is the specified pipe size.

Installation Notes

Installation must be performed by a licensed plumber, pipefitter, or qualified gas installer in accordance with IFGC requirements and the manufacturer's listed installation instructions. Shut off the gas supply and verify zero pressure at the line before making any connections. CSST requires bonding and grounding per applicable electrical and fuel gas codes, including NEC Article 250 and local amendments. Do not kink, over-bend, or install the tubing in contact with sharp metal edges without approved mechanical protection.
