Product Description
DIAMOND EYE 444000 is a 4.0" standard steel U-bolt saddle clamp built for reliable, budget-friendly sealing of slip-fit exhaust joints. Its heavy-duty 3/8" U-bolt and stamped saddle compress the tubing for a durable, leak-resistant connection on diesel or gas systems.
FAQ: WILL THIS FIT MY EXHAUST?
Yes—if you are clamping a slip-fit (expanded-overlap) joint on 4.0" nominal exhaust tubing. For butt-joint or V-band connections, use a band clamp or V-band kit instead.
FAQ: IS IT REUSABLE?
U-bolt saddle clamps can crimp the tubing. They’re best for permanent or semi-permanent joints. If you need frequent serviceability, consider a Torca band clamp.
FAQ: WHAT MATERIAL IS IT?
Standard steel with protective finish. For increased corrosion resistance, see our zinc-coated or stainless clamp options below.
