Granatelli Motor Sports 318530FT Heavy Duty Double O-Ringed Aluminum Interlocking Clamshell Clamps 3.0 in.

The Granatelli Motor Sports 318530FT is a heavy-duty, double O-ringed clamshell clamp set designed for high-performance exhaust and forced-induction applications. Engineered for a secure, leak-free connection, these aluminum interlocking clamshell clamps feature a dual O-ring seal design that creates positive clamping pressure on both sides of the joint, eliminating exhaust leaks even under extreme heat and vibration cycles.

This kit includes a 3.0-inch (76mm) weld-on ferrule set, providing a precision mating surface for the clamshell clamps to seat against. The weld-on ferrule system ensures a repeatable, consistent connection point — ideal for installations where the clamp may need to be removed and reinstalled for service or tuning access.

• 3.0 in. (76 mm) pipe diameter fitment
• Double O-ring seal design for maximum leak protection

The Granatelli Motor Sports 318530FT clamshell clamp system is the professional's choice for builders who need a strong, reusable, and airtight connection in demanding performance applications.
