Heavy-duty 17 gauge brass tubular components are used in plumbing drain systems where durability and long service life are important. These thick‑walled tubes form the traps, tailpieces and waste arms in sink and bathtub assemblies, and their extra material thickness helps them withstand years of use.

Materials and design

A 17 gauge brass tube has a wall thickness of about 1.3 mm, making it noticeably stronger than lighter 20 gauge tubing. The tubing is formed from high‑quality brass and often has a polished chrome or brushed nickel finish for corrosion resistance. Smooth interior walls help prevent debris buildup and ensure efficient drainage.

Advantages

• Durable construction: The thicker 17 gauge wall resists denting and deformation, providing a reliable, leak‑free drain connection.
• Long service life: Brass is naturally resistant to corrosion, and the heavy‑gauge tube maintains its structural integrity even under repeated use and cleaning.
• Code compliant: 17 gauge tubular meets most plumbing codes for traps and waste arms in residential and commercial installations.
• Attractive finish: Chrome or nickel plating offers a clean, polished look that complements modern fixtures while protecting the brass base metal.

Installation tips

• Match the tube diameter to the fixture: 1 \u00bc inch for lavatory drains and 1 \u00bd inch for kitchen and bath waste lines.
• Use the appropriate slip‑joint nuts and washers to connect traps, tailpieces and waste arms. Hand‑tighten, then give a small additional turn to seal; over‑tightening can damage the washers.
• After assembly, run water and check for leaks. Tighten fittings gently if any seepage occurs. Periodically inspect and clean the tubing to maintain proper drainage.
