FAQ
Is this clamp reusable?Yes. Torca band clamps can typically be loosened and re-torqued for service work if undamaged.
What’s the difference between 409, 430, and 304 stainless?
409 is durable and cost-effective for daily drivers; 430 has a brighter finish; 304 offers the highest corrosion resistance. Choose based on climate and budget.
Will it crush my tubing like a U-bolt clamp?
No. Torca band clamps are designed to seal evenly without crushing roundness, making future disassembly easier.
