Sioux Chief 649TX V-Sleeve Stainless Steel PEX Press Sleeve

The Sioux Chief 649TX V-Sleeve is a stainless steel press sleeve engineered for rough-in PEX connections using ASTM F1807 and F2159 PEX fittings in conjunction with SDR9 PEX tubing manufactured to ASTM F876 or ASTM F877. This V-Sleeve is available in 1/2", 3/4", and 1" sizes to match the tube and fitting diameter in use. The sleeve's design delivers 360° compression across all sealing surface areas, creating a reliable mechanical connection when installed with a compression tool designed specifically for the V-Sleeve or F3347 metal press sleeve system. Built for behind-the-wall and under-floor plumbing installations, the sleeve can be pre-loaded onto the fitting or tube before the tube is fully inserted, and the open sleeve design allows the installer to visually confirm that the tube is fully inserted to the tube stop on the fitting before compressing — a practical quality-control step for plumbers working fast on rough-in runs.

Key Features

  • Size Range: Available in 1/2", 3/4", and 1" sleeve sizes for SDR9 PEX tubing connections.
  • Durable Construction: Stainless steel sleeve construction (SS) for a long-lasting mechanical press connection.
  • 360° Compression: Compresses evenly across all sealing surface areas for a consistent seal on PEX fittings.
  • Pre-Load Flexibility: Sleeve can be pre-loaded onto either the fitting or the tube prior to assembly, simplifying rough-in sequencing.
  • Visual Insertion Check: Open design lets installers see that the tube is fully inserted to the tube stop on the fitting before pressing.
  • Compatible Connection System: For use with ASTM F1807 and F2159 PEX fittings and SDR9 PEX tubing manufactured to ASTM F876 or ASTM F877; requires a compression tool designed for the V-Sleeve or F3347 metal press sleeve connections.
  • Patent-Protected Design: Manufactured under Patent# 8,123,257.

Sioux Chief 649TX2 – Frequently Asked Questions

1) Can I use the Sioux Chief 649TX V-Sleeve with a standard crimp ring tool?
No. The 649TX V-Sleeve requires a compression tool built specifically for the V-Sleeve or for F3347 metal press sleeve connections. A copper crimp ring tool (ASTM F1807 crimp jaws) will not press it correctly. If your crew only owns crimp ring tools, you need copper crimp rings instead of this sleeve.
2) What PEX tubing and fittings does the Sioux Chief 649TX sleeve work with?
It is made for ASTM F1807 and F2159 PEX fittings (brass insert and poly alloy insert fittings) used with SDR9 PEX tubing manufactured to ASTM F876 or F877. Match the sleeve size to the tube and fitting diameter you are joining, 1/2, 3/4, or 1 inch.
3) Will a stainless press sleeve pass inspection on a potable water rough-in?
The 649TX is UPC listed and third-party tested to ASTM F877, which gives an inspector documented basis for the connection on residential and commercial potable PEX rough-in. Confirm your local code adopts UPC or accepts UPC-listed components.
4) Can I use the 649TX sleeve on PEX-AL-PEX or on PEX tubing that isn't SDR9?
No. The sleeve is dimensioned for SDR9 PEX made to ASTM F876 or F877. PEX-AL-PEX and non-SDR9 tubing have different wall and outside diameters, so the press will not seal reliably. Use the fitting system specified for that tubing instead.
5) Which 649TX part number do I order for 3/4 inch PEX?
Order 649TX3 for 3/4 inch. The 1/2 inch sleeve is 649TX2 and the 1 inch is 649TX4. Sleeve size follows the nominal tube size, so a 3/4 inch PEX branch takes 649TX3.
6) How do I know the PEX tube is fully inserted before I press the sleeve?
That is what the open V-Sleeve design is for. You can see the tube through the sleeve and confirm it is seated against the tube stop on the fitting before compressing. The sleeve can also be pre-loaded onto either the fitting or the tube before final insertion, which helps when you are working in a tight joist bay.
7) Is a stainless steel press sleeve okay to bury behind a wall or under a slab-level floor?
The 649TX is built for behind-the-wall and under-floor rough-in, and the sleeve itself is stainless steel rather than copper, so it holds up better in damp concealed locations. It makes a mechanical press connection with 360 degree compression across the sealing surfaces.
8) Are Sioux Chief V-Sleeves made in the USA?
Yes, the 649TX V-Sleeve is manufactured in the United States, which matters on jobs with domestic sourcing requirements. It is also made under Patent 8,123,257.
