Asc 38A.WF50 1-1/2 in 50 Ft Csst Corrugated Ss Tubing

Product Description

The ASC Engineered Solutions 38A.WF50 is a corrugated stainless steel tubing (CSST) product manufactured from 304 stainless steel and supplied in a 50-foot coil. The tubing measures 1-1/2 inches in nominal diameter and features a black jacket. CSST of this type is designed to distribute natural gas or propane within residential and commercial structures, running from the meter or regulator to appliances and branch takeoffs. It is installed by licensed plumbers and gas fitters who need a flexible, code-listed alternative to rigid black iron pipe in tight spaces or long runs.

This tubing is suited for interior gas distribution in both residential and light commercial applications. Its flexibility allows routing through walls, floors, and mechanical spaces with fewer fittings than rigid pipe. The 50-foot coil length supports longer single-run installations, reducing the number of joints and potential leak points. It is appropriate for use with natural gas and LP gas systems where the applicable local codes permit CSST installation.

Installation Notes

CSST must be installed by a licensed plumber or gas fitter in accordance with the manufacturer listing requirements and the applicable fuel gas code, typically the IFGC or NFPA 54. Shut off the gas supply at the meter or service valve and verify zero pressure before cutting or fitting the tubing. Bonding and bonding requirements for CSST vary by jurisdiction and edition of the adopted code — always verify local requirements before installation. Do not use compression or standard threaded fittings not rated for CSST; use only compatible listed end fittings designed for this product.
