Description
The Mishimoto MMCLAMP-325 is a stainless steel T-bolt clamp engineered to secure pipes, hoses, and couplers with an outer diameter between 3.15 inches (80.01 mm) and 3.39 inches (86 mm). Unlike a standard worm gear clamp, this T-bolt clamp is built for projects that demand more clamping force, using the same durable stainless steel found in Mishimoto’s worm gear clamp lineup. A 0.75-inch band and an included self-locking nut work together to keep the clamp seated tight even under vibration.
As part of Mishimoto’s Fabrication lineup, this T-bolt clamp is a purpose-built solution for fabricators, tuners, and DIYers who need more reliable clamping force than a typical worm gear clamp can offer. The T-bolt design distributes clamping pressure evenly around the band, and because the clamp is reusable, it can be removed and reinstalled as a project evolves. Stainless steel construction is intended to resist corrosion longer than zinc-plated clamps, making this a practical choice for piping and engine bay applications where long-term durability matters. Each clamp is sold individually and is backed by the Mishimoto Lifetime Warranty.
Vehicle Applications
The Mishimoto MMCLAMP-325 T-bolt clamp is not vehicle-specific; rather, it is sized to fit any pipe, coupler, or hose with an outer diameter from 3.15 inches (80.01 mm) up to 3.39 inches (86 mm). This makes it a versatile option for a wide range of fabrication and piping projects wherever a clamp in this diameter range is required.
