Sioux Chief 285-S Flexible PEX Lavatory Supply Line with Plastic Ferrule

The Sioux Chief 285-S is a flexible PEX lavatory and sink supply line built for reliable, leak-resistant connections beneath fixtures, sharing a common 3/8" connection size across the line. Available in 20" and 30" overall lengths, the 285-S gives plumbers and contractors the flexibility to match a range of rough-in and stop-valve configurations without forcing or over-bending the tube. Each supply line ships with a plastic ferrule fitting already in place to simplify installation and support a secure, watertight seal at the connection point. Manufactured in the United States, the 285-S delivers consistent, dependable performance for both new construction and fixture replacement projects.

Key Features

  • Trade Size: 3/8" connection size, available in 20" and 30" overall lengths to match a range of lavatory and sink rough-in distances.
  • Flexible PEX Construction: Smooth, flexible PEX tubing resists kinking and eases routing through tight cabinet spaces and around obstructions during installation.
  • Plastic Ferrule Connection: Each supply tube ships with a plastic ferrule already fitted, supporting a secure, leak-resistant seal at the fixture or stop-valve connection.
  • Consistent Sizing Across the Line: The 3/8" connection size is shared across both available lengths, so installers can standardize on one connection size while selecting the length that fits the job.
  • Country of Origin: Manufactured in the United States for consistent manufacturing quality.

Sioux Chief 285-S0412000 – Frequently Asked Questions

1) What lengths does the Sioux Chief 285-S PEX lavatory supply line come in?
Two lengths: 20 inches and 30 inches overall, both on a 3/8 inch connection. Order the 20 inch (285-S0412000) when the stop valve sits close under the bowl, and the 30 inch (285-S0413000) for deeper vanities, wall-mount lavs, or a stop set low in the cabinet. Running one length long and letting the PEX take a gentle sweep is better than stretching a short tube straight.
2) Does the 285-S supply line come with the ferrule, or do I need to buy one?
The ferrule is already on the tube. Each 285-S ships with a plastic ferrule fitted at the factory for the seal at the fixture or stop-valve connection, so there is no separate ferrule to source. You still supply the compression nut side as your stop valve requires.
3) Is PEX or a braided stainless connector better for a lavatory supply?
Different jobs. The 285-S is a PEX tube you cut and route, so it holds a shape, resists kinking, and works well where the run from stop to faucet is a clean sweep inside a cabinet. A braided stainless connector with a female nut is faster when the faucet already has a male threaded tailpiece and you just want a plug-and-tighten connection. For a bare smooth faucet tailpiece or a rough-in where you want the tube trimmed to length, the PEX supply is the one to use.
4) Can I use the Sioux Chief 285-S on a kitchen sink, or is it only for lavatories?
Both. The 285-S is listed for lavatory and sink faucet supply connections, stop valve to fixture runs, fixture replacement work, and new construction rough-in. The deciding factor is the connection size (3/8 inch) and whether the 20 or 30 inch length reaches your stop, not the fixture type.
5) Is the Sioux Chief 285-S made in the USA? We have a domestic sourcing requirement.
Yes, the 285-S PEX supply line is manufactured in the United States. That is the stated country of origin for the product, which is what procurement groups with domestic-content preferences typically need on file.
6) Can I standardize on one supply line across a building full of lavatories?
That is the practical use case. Both the 20 inch and 30 inch 285-S share the same 3/8 inch connection and the same factory-fitted plastic ferrule, so a maintenance crew stocks one connection type and just picks the length that suits the rough-in at each opening. For multi-family or hospitality turns, keeping both lengths on the truck covers shallow and deep vanity cabinets without changing fittings.
7) What material is the Sioux Chief 285-S supply tube, and can I bend it around a disposal or trap?
The tube is PEX. It is flexible and resists kinking, so it can be routed around a trap arm, disposal body, or cabinet obstruction without the hard crease a rigid tube would take. Keep the bends as sweeping curves rather than tight corners and do not force the tube at the ferrule connection.
