Our 2-1/2 inch OD Sanitary Stainless Steel Tubing, crafted from 304/316L stainless steel. Ideal for home brewing, small-scale food processing, DIY water filtration, or aquarium systems, it offers corrosion resistance, smooth inner walls to prevent bacterial buildup, and compliance with food-grade safety standards. Lightweight yet durable, it’s easy to cut and install, making it perfect for both hobbyists and small businesses prioritizing cleanliness and longevity.

Why You’ll Need It:

Rust-Proof Superpower: Survives salty air, pool chemicals, and garden fertilizers.
Easy to Customize: Cut, bend, or weld with basic tools (hacksaw, tube bender, MIG welder).
Sleek & Professional: Polished or brushed finish – looks great on visible projects like bike racks or patio decor.
No-Hassle Sizing: Pre-cut 1ft to 6ft lengths (or order bulk coils) – no need to wrestle with giant industrial pipes.

The pressures shown in the table above are calculated using Barlow's Formula and the following properties:
• material: 304
• yield strength (PSI): 30,000
• tensile strength (PSI): 75,000
Working Pressure = ¼ of Burst Pressure, these calculate from -20°F to 100°F.
