Sioux Chief 5583 CTS Copper Tube Insulator for 1/2" & 3/4" Copper Tube, US-Made

Sioux Chief 5583 CTS Copper Tube Insulator for 1/2" & 3/4" Copper Tube, US-Made

The Sioux Chief 5583 is a CTS (Copper Tube Size) copper tube insulator built for rough-in plumbing, hydronic, and mechanical piping work, available across the two most common copper tube diameters on the jobsite: 1/2" and 3/4". Manufactured in the United States and supplied in cartons of 500 EA, the 5583 line gives plumbers, service technicians, and distributors a dependable truck-stock item for high-volume installation and repair work across residential and commercial projects. Because both the 1/2" and 3/4" sizes share the same CTS design and country-of-origin quality control, crews can standardize on a single insulator family while still covering the copper tube diameters they encounter most often on a typical service call or rough-in.
