Sioux Chief 649Y Series PEX SDR9 Mechanical Cinch Clamp, USA-Made

The Sioux Chief 649Y Series Mechanical Cinch Clamp is engineered to secure PEX SDR9 tubing onto fittings, creating a tight, leak-resistant joint on PEX SDR9 piping systems. The series is available in 1/2", 3/4", and 1" sizes across the 649Y2, 649Y3, and 649Y4PK1 configurations, letting plumbing contractors and stocking distributors match clamp size and pack quantity to the tubing size a given job requires. Every clamp in the 649Y Series is manufactured in the United States and is engineered strictly for PEX SDR9 piping; it is not designed for use with polybutylene (PB) tube. The cinch-style clamping action compresses evenly around the tubing and fitting barb for a consistent, dependable seal at every connection.

Key Features

  • Size Range: Available in 1/2", 3/4", and 1" sizes across the 649Y2, 649Y3, and 649Y4PK1 configurations to match clamp size and pack count to the job.
  • PEX SDR9 Compatibility: Engineered specifically for PEX SDR9 piping to deliver proper clamp engagement and a secure, leak-resistant connection at the fitting.
  • Not for PB Tube: These cinch clamps are not designed for use with polybutylene (PB) tube, so reserve them exclusively for PEX SDR9 tubing systems to maintain a code-compliant joint.
  • Cinch-Style Clamping Action: The cinch clamp design compresses evenly around the PEX tubing and fitting barb, helping installers achieve a consistent, dependable seal on every connection.
  • Bagged for Jobsite Stocking: Packaged in bag quantities so plumbing contractors and wholesale distributors can keep clamps organized and ready on the truck or at the counter.
  • Made in the USA: Manufactured in the United States, giving installers a domestically produced clamp backed by consistent manufacturing quality.

Sioux Chief 649Y2 – Frequently Asked Questions

1) What PEX sizes do the Sioux Chief 649Y clamps cover?
Three trade sizes: 1/2 inch (649Y2), 3/4 inch (649Y3), and 1 inch (649Y4PK1). Match the clamp to the tubing size, since a cinch clamp only compresses correctly on the diameter it was sized for.
2) Are Sioux Chief 649Y cinch clamps made in the USA?
Every clamp in the 649Y Series is manufactured in the United States. That matters on public work and institutional jobs with domestic sourcing requirements, where the country of origin has to be documented on the submittal.
3) Can I use these cinch clamps with PEX-A as well as PEX-B tubing?
The qualifier that matters for the 649Y clamps is the dimension standard, not the cell classification: they are engineered for PEX SDR9 tubing, which is the standard dimension ratio for ASTM PEX plumbing tube in 1/2, 3/4 and 1 inch. If your tube is SDR9 PEX and the fitting is a barbed insert fitting, the clamp is the right part.
4) Do I need a special tool to install Sioux Chief 649Y clamps?
Yes, these are mechanical cinch clamps, so they are set with a cinch clamp tool that pinches the ear closed around the tubing and fitting barb. The clamps themselves ship bagged; the tool is a separate purchase.
5) Can I use cinch clamps instead of copper crimp rings on a PEX repipe?
Yes, cinch clamps and copper crimp rings are two different mechanical methods on the same barbed insert fittings, and a cinch clamp like the 649Y only needs a one-handed cinch tool rather than a sized crimp jaw per diameter. Crimp rings are often preferred where the inspector or spec already calls them out. Cinch clamps are easier in tight joist bays and on manifold banks because they can be set from one side.
6) Are these clamps sold individually or in bags?
The 649Y clamps come in bag quantities, which is how most contractors and counters stock them. Pack quantity varies by configuration across the 649Y2, 649Y3, and 649Y4PK1, so pick the size you need and order by that part number.
7) Will the 649Y clamps hold on a PEX manifold connection?
They will. Securing PEX tubing to fittings and manifolds is one of the intended applications, in new construction rough-in as well as repair and repipe work, as long as the tube is PEX SDR9 and the manifold ports are barbed inserts.
