Sioux Chief 928-2 1/2" CTS Dry Seal Pipe Collar

The Sioux Chief 928-2 is a 1/2" CTS dry seal pipe collar designed for rough-in installations where pipe or tubing penetrates a wall cavity. Its thin, tapered profile compresses tightly against the wall surface to create a watertight seal around the pipe or tube, helping block moisture intrusion that can lead to mold growth inside the wall cavity. This collar is sized for 1/2" CTS (copper tube size) applications and ships from Sioux Chief in bulk packaging of 500 EA, making it a practical stocking item for plumbing contractors handling multiple rough-in penetrations on a job site.

Key Features

  • Trade Size: Sized for 1/2" CTS pipe or tubing penetrations.
  • Watertight Seal: Creates a watertight seal around the pipe or tube where it passes through a wall.
  • Moisture Barrier: Helps keep moisture out of the wall cavity, which helps prevent mold growth behind the wall.
  • Tapered Design: Thin, tapered construction compresses tightly against the wall surface for a secure, snug fit around the pipe.
  • Dry Seal Function: Functions as a dry seal collar, separating the finished wall surface from the penetration point without relying on adhesives or caulking.

Sioux Chief 928-2 – Frequently Asked Questions

1) Will the Sioux Chief 928-2 collar fit 1/2 inch PEX, or is it only for copper?
The 928-2 is sized to 1/2 inch CTS, which is copper tube size. Since 1/2 inch PEX is made to the same CTS outside diameter, the collar seals around 1/2 inch CTS copper or PEX tubing at a wall penetration. If your tubing is a different trade size, you need the matching collar size instead.
2) What does a dry seal pipe collar do that caulking at the pipe penetration does not?
A dry seal collar seals mechanically. The 928-2 has a thin, tapered profile that compresses against the wall surface around the pipe, so you get a watertight seal at the penetration without adhesive or caulk. That keeps moisture out of the wall cavity, which is where mold starts behind a finished wall. No cure time, and nothing to re-apply if the trim plate comes off later.
3) How does the Sioux Chief 928-2 pipe collar ship? Is it sold individually?
It ships in bulk from Sioux Chief, 500 each per case. That is a stocking quantity aimed at crews running a lot of rough-in penetrations rather than a one-off repair, so plan on buying the case pack.
4) At what stage of a plumbing rough-in do you install a 1/2 inch CTS pipe collar?
It goes on at rough-in, where the tube passes out of the wall cavity, before the finished wall surface and escutcheon go on. The collar separates the finished wall from the penetration point and compresses against that surface to seal around the tube. Used on both new construction and renovation work, residential and commercial.
5) Is the Sioux Chief 928-2 collar made in the USA?
Yes, the 928-2 dry seal pipe collar is manufactured by Sioux Chief in the United States, which matters if you are working a job with domestic-sourcing requirements.
6) What is the Sioux Chief part number for the 1/2 inch CTS dry seal collar?
Order it as Sioux Chief 928-2. The 928 series is sized by trade size, so the -2 suffix is the 1/2 inch CTS version. Larger tubing takes a different suffix in the same family.
