Sioux Chief 640XG02 No-Lead Brass PEX Barb Plug, 1/2"

The Sioux Chief 640XG02 is a one-piece, no-lead brass PEX barb plug sized for 1/2" PEX tubing. Plumbers and contractors use this barb plug to cap or terminate a PEX line during rough-in, pressure testing, or as a permanent dead-end on a branch that won't be put into service. Its one-piece brass body is designed to insert directly into 1/2" PEX tubing and be secured with a standard PEX crimp ring or cinch clamp, giving installers a quick, reliable way to seal off a line without re-routing tubing or swapping fittings mid-job.

Key Features

  • Trade Size: 1/2" PEX barb connection for direct insertion into 1/2" PEX tubing.
  • Durable Construction: One-piece brass body resists corrosion and holds up under rough-in and pressurized-line conditions.
  • No-Lead Alloy: Manufactured from no-lead brass for use on potable water lines where low-lead requirements apply.
  • Versatile Use: Suitable for both temporary installation (pressure testing a line before fixtures are set) and permanent installation (capping an unused branch).
  • Simple Installation: Barb design accepts a standard PEX crimp ring or cinch clamp for a secure, leak-resistant connection.
  • Bulk Packaging: Packaged 1000 EA per case for contractors and distributors stocking high-volume rough-in supplies.

Sioux Chief 640XG02 – Frequently Asked Questions

1) Will the Sioux Chief 640XG02 plug work with 1/2 inch PEX crimp rings, or do I need cinch clamps?
Either one. The 640XG02 is a barb-style insert fitting, so it goes into the 1/2 inch PEX tubing and gets secured with a standard copper crimp ring or a stainless cinch clamp, whichever tool you already carry. No proprietary tooling and no special ring size.
2) Can I use a brass PEX plug on a potable water line?
Yes. The 640XG02 is made from no-lead brass, so it's intended for potable water service where low-lead requirements apply. The body is one piece, with no internal seal or washer to fail on a pressurized line.
3) Do I need a plug or a cap to dead-end a 1/2 inch PEX line?
Depends on which end you have. A plug like the 640XG02 inserts INTO the tubing and is clamped over the barb, so it's what you want when you have an open run of 1/2 inch PEX to terminate. A cap goes over a male barb or threaded stub instead. If you are closing off cut tubing at rough-in, the plug is the right part.
4) Is this PEX plug meant to be temporary for pressure testing, or can I leave it in the wall?
Both. Plumbers use the 640XG02 to seal a 1/2 inch PEX run for pressure testing before fixtures are set, then pull it at trim-out, and it's equally used as a permanent dead-end on a branch that won't be put into service. Being one-piece brass with a clamped barb joint, it isn't a test-only part.
5) How does the Sioux Chief 640XG02 PEX plug ship, and is it a bulk-only item?
The 640XG02 is packaged 1000 each per case, which is how it's stocked for contractors and distributors running high volumes of rough-in fittings. Worth knowing if you're ordering for a single repair versus standardizing a truck or warehouse stock.
