Product Description
Diamond Eye BC300S304 is a universal 3.00-inch Torca-style band clamp made from corrosion-resistant 304 stainless steel. It delivers an even, 360° seal on butt-joint (end-to-end) exhaust connections without crushing tubing—perfect for serviceable joints on diesel and heavy-duty setups. Includes metric hardware for reliable clamping torque.
Why this clamp? Torca-style preformed bands use a reaction block to convert bolt torque into uniform hoop stress, creating a gas-tight seal that resists loosening and exhaust leaks over time.
Fitment
- Pipe Size: 3.00" (OD-to-OD butt-joint connections)
- Joint Type: Butt-joint (not for lap-joint/slip-fit)
- Material: 304 Stainless Steel band and hardware
- Use Case: Universal—fits any 3.00" exhaust sections where a serviceable, leak-resistant joint is required
Cross-Reference / Alternatives (Diamond Eye only)
- Need aluminized instead? BC300A 3.00" Aluminized Torca Band Clamp
- Prefer 409 stainless? BC300S409 3.00" 409 Stainless Torca Band Clamp
- Prefer bright 430 stainless? BC300S430 3.00" 430 Stainless Torca Band Clamp
- Need 4.00" size? BC400S304 4.00" 304 Stainless Torca Band Clamp
- Looking for a 3.00" lap-joint clamp? L30SA 3.00" Stainless Torca Lap-Joint Clamp
Helpful Notes
- Tighten evenly and re-torque after heat cycles for best long-term sealing.
- For slip-fit/lap joints, use a lap-joint style clamp (e.g., L30SA), not a butt-joint band clamp.
FAQ
Is this clamp truly universal?
Yes—if both pipes are true 3.00" OD and the joint is an end-to-end (butt-joint) connection. For slip-fit/lap joints, choose a lap-joint clamp instead.
Will 304 stainless resist rust in winter/salt conditions?
304 stainless offers excellent corrosion resistance versus aluminized or 409 stainless, making it a solid choice for harsh climates.
What hardware is included?
Comes with metric hardware appropriate for the Torca reaction block design for consistent, repeatable clamping force.
Butt-joint vs. lap-joint—what’s the difference?
Butt-joint aligns two 3.00" OD pipes end-to-end and uses a preformed band clamp like this one. Lap-joint overlaps an OD pipe into an ID component and uses a lap-joint clamp (e.g., L30SA).
