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.
