The Vibrant spring loaded T-bolt clamps come as a pack of two and compensate for hose expansion and contraction caused by thermal and pressure changes. The spring keeps even clamping tension on the connection. The clamp band and floating bridge use 300-series stainless steel, while the T-bolt, lock nut, and spring are zinc-plated steel. The adjustable range is 3.22 in to 3.52 in. Recommended torque is 50 in-lbs.
