Sioux Chief 663-07838SS Self-Seal Pipe Insulation Sleeve, 7/8" ID x 3/8" Wall, 300 ft.

The Sioux Chief 663 is a self-seal pipe insulation sleeve built to wrap and protect copper, CPVC, or PEX water lines with a 7/8" inside diameter and a 3/8" wall thickness for consistent, even coverage along the run. Each 663-07838SS carton provides 300 ft. of insulation in 6' sections for full coverage across long runs. The self-sealing adhesive seam closes the insulation around the pipe without additional tape, contact cement, or staples, speeding up rough-in and retrofit insulation work. Manufactured in the United States, the Sioux Chief 663 delivers consistent, ready-to-install coverage for exposed or concealed water lines on residential and commercial jobs.

Key Features

  • Trade Size: 7/8" ID x 3/8" wall thickness, sized to fit the pipe diameter requiring this insulation.

  • 300 ft. Total Length: Supplied in 6' sections totaling 300 ft., enough to cover long runs without reordering.
  • Job-Site Efficiency: Pre-sized, self-sealing design reduces installation steps compared with wrap-and-tape insulation methods.
  • Pipe Compatibility: Suited to copper, CPVC, or PEX water lines in exposed or concealed runs.

Why Sioux Chief?

Sioux Chief builds rough-in plumbing supplies for professional installation, and the 663 self-seal pipe insulation sleeve reflects that same focus on practical, job-ready design. The self-sealing seam and pre-sized 7/8" ID x 3/8" wall construction help plumbers move through pipe insulation runs efficiently instead of stopping to tape or glue every section by hand. Delivering 300 ft. in 6' sections keeps trucks and shelves stocked for crews running multiple jobs at once. Combined with U.S. manufacturing that supports consistent quality control from box to box, the Sioux Chief 663 is a straightforward choice for reliable, ready-to-install pipe insulation on your next rough-in or retrofit job.

Sioux Chief 663-07838SS – Frequently Asked Questions

1) Do I need tape or glue to close Sioux Chief 663 self-seal pipe insulation?
No. The seam carries a self-sealing adhesive strip, so you press it closed around the pipe in one step, no tape, contact cement, or staples. You will still want tape or fitting covers at elbows and tees where two sections butt together, since those joints are not part of the self-seal seam.
2) Can I use this insulation on PEX and CPVC, or is it copper only?
Copper, CPVC, and PEX water lines are all covered, as long as the tube measures 7/8 inch outside diameter. The sleeve is a wrap, not a fitting, so the pipe material does not matter to the fit, only the outside diameter does.
3) How much insulation comes in a carton of 663-07838SS?
One carton is 300 feet total, made up of 50 pieces at 6 feet each. Plan your takeoff in 6 foot increments, since that is the length you are cutting from on the job.
4) Will 3/8 inch wall insulation stop sweating on cold water lines in a basement?
That is one of the intended uses. The 3/8 inch wall on the 663 is specified for condensation control on exposed plumbing and for freeze protection in unconditioned spaces like mechanical rooms and basement runs. For chilled water or high humidity work where an engineer has called out a thicker wall, 3/8 inch will not meet that spec and you need a heavier wall sleeve.
5) What is the exact part number to order 7/8 inch ID Sioux Chief self-seal insulation?
Order Sioux Chief 663-07838SS. The number breaks down as the 663 self-seal insulation series, 078 for the 7/8 inch inside diameter, and 38 for the 3/8 inch wall. A different ID or wall is a different suffix in the same 663 series.
6) Can this insulation be used on hot water lines, or just cold?
Both. The 663 is listed for insulating hot and cold water supply lines, so the same carton covers the hot and cold runs on a rough-in as long as both are 7/8 inch OD.
