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

Product Description

The ASC ENGINEERED SOLUTIONS 20C.WF100 is a corrugated stainless steel tubing (CSST) assembly used to distribute natural gas and propane in residential and commercial piping systems. Manufactured from 304 stainless steel with a black outer jacket, this tubing measures 3/4 inches in diameter and runs 100 feet in length. It is produced domestically and carries a full set of third-party listings including ANSI LC1, ASTM A240/E84, CSA 6.26/112940, IAPMO PS 3353, ICC ESR-1879, and UL R18357. Licensed plumbers and gas fitters are the primary installers of this product.

This CSST is suited for below-grade, above-grade, interior, and concealed gas distribution runs in both residential and light commercial construction. The black jacket provides UV and mechanical protection along the tubing length. The 100-foot coil length supports long continuous runs with fewer fittings, reducing potential leak points. It is appropriate for natural gas and LP gas systems where a listed flexible gas piping product is required by code.

Key Features

• 304 stainless steel corrugated core for flexibility and corrosion resistance

Compatibility

Designed as an OEM-style listed CSST product for use with compatible manufacturer fittings and termination hardware in natural gas and LP gas distribution systems where 3/4-inch CSST is specified.

Installation Notes

CSST gas piping must be installed by a licensed plumber or gas fitter in accordance with IFGC requirements and all applicable local codes. Shut off the gas supply at the meter or main valve and verify zero pressure before making any connections. Bonding and bonding clamp requirements vary by jurisdiction — consult local amendments to NFPA 54 and IFGC before installation. Do not over-bend or kink the tubing, and follow the fitting manufacturer's torque and assembly instructions for all termination connections.
