SS T-Bolt Clamps for Silicone or PVC Hose - Nominal 3-1/2" Hose (3.78" - 4.09" Range)

These are very strong and secure clamps for critical marine installations. Trident Marine T-Bolt Clamps are built with safety in mind.
The 3/4" (19 mm) wide band and uniform 360° clamping pressure ensures a greater area of coverage for a positive and strong hose connection.
They are ideal for below-the-waterline applications.
We recommend using two clamps on each end of a wet exhaust installation.

Series 720 clamps have an extra-wide 3/4" 316 stainless steel band with a heavy duty 1/4" 18-8 stainless steel bolt and nylon insert lock nut.
Torque to 75 inch-pounds maximum.

These 720 Series clamps come in two size ranges: L (Long) and HT (Hi-Temp)
• L Series clamps have a relatively longer T-bolt for a given size clamp - sized for thicker walled, black rubber water/exhaust hose.
• HT Series clamps have a relatively shorter T-bolt for the same size clamp - sized for thinner walled, blue silicone high temp exhaust hose.
Otherwise, these hose clamps are identical.
• In sizes smaller than 3" the difference between blue and black hoses is not that significant, and there are no L or HT designations. The same clamp is used for both types of hose.
• 3 year warranty.
