Helpful Notes
- Butt-joint vs. lap-joint: This clamp is for butt-joint (end-to-end) connections. For lap-joint (slip-fit) connections, see Diamond Eye “Lxx” series lap-joint clamps (e.g., L35AA/L35SA).
- Torque the fastener evenly and recheck after heat cycles for best seal retention.

Will this clamp fit a slip (lap-joint) connection?
No. This is a butt-joint band clamp for OD-to-OD connections. For lap-joint (slip-fit) joints, use the Diamond Eye L-series lap-joint clamps (e.g., L35AA/L35SA).
Is 430 stainless corrosion-resistant?
Yes—430 stainless provides solid corrosion resistance with a bright finish at a great value. For maximum corrosion resistance, consider 304 stainless (BC350S304).
What torque should I use?
Torque requirements vary by hardware; tighten evenly until the band fully seats around the joint, then recheck after the first few heat cycles.
