Sioux Chief 632X335 3/4" Sweat x PEX 90° Short Radius Elbow

The Sioux Chief 632X335 is a one-piece solid copper 90° short radius elbow that transitions from a 3/4" female sweat (FMST) connection to 3/4" PEX tubing in a single fitting. Built for rough-in plumbers who need a reliable, no-hassle way to tie copper stub-outs into PEX distribution runs, this elbow eliminates the extra joint that a separate copper-to-PEX adapter and standalone elbow would otherwise require. Because it is machined from one solid piece of copper rather than assembled from multiple components, there is one less solder joint and one less potential leak point on the job. It is a practical, multipurpose fitting for any rough-in crew transitioning piping materials behind a wall or under a floor.

Key Features

  • Trade Size: 3/4" sweat x 3/4" PEX connection sized for standard residential and light commercial supply lines.
  • Durable Construction: One-piece solid copper body resists corrosion and holds up to the thermal cycling typical of hot and cold supply lines.
  • Dual Connection Type: Female sweat (FMST) end solders directly to copper pipe, while the opposite end is sized for direct PEX tubing connection, simplifying material transitions in a single fitting.
  • 90° Short Radius Elbow: Short-radius bend geometry is built for tight rough-in spaces where a standard long-radius elbow will not fit.
  • One-Piece Design: Solid copper construction reduces the number of joints compared to using a separate adapter plus elbow, cutting down on potential leak points.
  • Multipurpose Use: Works as a general-purpose sweat x PEX elbow anywhere a copper stub needs to turn 90° into a PEX run.

Technical Specifications

  • Trade Size: 3/4" FMST x 3/4" PEX
  • Angle: 90° short radius
  • Material: One-piece solid copper
  • Country of Origin: United States
  • Packaging: 250 EA per case

Typical Applications

  • Residential and commercial rough-in plumbing
  • Copper-to-PEX supply line transitions
  • Tight-clearance 90° direction changes behind walls or under floors
  • New construction water distribution rough-in
  • Remodel and repipe projects converting copper stub-outs to PEX

Why Sioux Chief?

Sioux Chief builds this 632X335 elbow from one solid piece of copper rather than an assembled multi-part fitting, giving plumbers a dependable sweat x PEX transition with fewer joints to solder and fewer potential failure points. For crews stocking rough-in trucks with reliable transition fittings, this elbow is a straightforward, multipurpose solution for joining copper and PEX piping systems.

Sioux Chief 632X335 – Frequently Asked Questions

1) What size pipe does the Sioux Chief 632X335 elbow connect?
It ties 3/4 inch copper to 3/4 inch PEX in one fitting. One end is a 3/4 inch female sweat (FMST) socket that solders onto 3/4 inch copper pipe; the other end is sized for 3/4 inch PEX tubing. Same trade size on both ends, so it is a straight material transition with no size change.
2) Can I use one fitting to turn a copper stub into a PEX run instead of an adapter plus an elbow?
That is exactly what the 632X335 does. It combines the copper-to-PEX transition and the 90 degree turn in a single one-piece solid copper body, so you solder one joint instead of soldering an adapter and then a separate elbow. Fewer joints behind the wall, fewer leak points.
3) Will a short radius elbow fit in a tight stud bay where a standard sweep elbow won't?
Short radius is the reason to pick this one. The 632X335 uses a tight 90 degree bend geometry intended for rough-in spaces where a long-radius elbow will not clear. If you have room for a standard sweep and want less flow restriction, a long-radius fitting is the better choice; in a cramped bay or under a floor, the short radius is what gets the turn made.
4) Is the PEX end of this Sioux Chief elbow crimp or push-fit?
The PEX end is a plain copper barb sized for direct 3/4 inch PEX tubing connection, so it is secured with the ring method your system uses (crimp ring, clamp, or compression sleeve per your tool set). It is not a push-to-connect body. The copper side is a female socket for sweat soldering.
5) Is this elbow all copper, and will it hold up on a hot water line?
The body is machined from one solid piece of copper, not an assembly of parts. Copper resists corrosion and takes the thermal cycling of hot and cold potable supply lines, so it works on either side of the system.
6) How is the Sioux Chief 632X335 packaged for a contractor buying in bulk?
Case quantity is 250 each. That suits a supply house or a repipe crew stocking trucks; the fitting itself is a single model, 632X335, with no size or finish options to specify.
7) Where is the Sioux Chief 632X335 elbow made?
Made in the United States. That matters on public and institutional jobs carrying domestic-sourcing requirements for plumbing materials.
8) Is there one part number to order, or do I need to pick a configuration?
One part number: Sioux Chief 632X335. It is a single configuration, 3/4 inch female sweat by 3/4 inch PEX, 90 degree short radius, solid copper. Nothing else to specify on the order.
