2-1/2" OD Stainless Steel Pipe

Bright Annealed Polished Sanitary Tubing ASTM A270
Available in 316L Stainless Steel
Stamped with Heat Lot Number
Manufactured in accordance with 3A Standards for sanitary line process requirements

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.

Real Stories from Real Users

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.
