CHUN YUNG DA TT Heavy Duty Hose Clamps

CHUN YUNG DA TT Heavy Duty T-Bolt Hose Clamps are adjustable 36–39mm (1.42–1.54") stainless-steel clamps built for high-torque, corrosion-resistant sealing on exhaust, charge air, and fluid hoses.

These four-pack T-bolt clamps combine a wide band, double solid T-nuts, and 304 stainless-steel construction to give a durable, hose-friendly fastening solution where pressure, heat, or vibration are present. Designed for use on 1.5-inch outer-diameter pipes and hoses (36–39mm), they prioritize even clamping force and long-term rust resistance so connections stay tight without cutting or deforming the hose.

How do these clamps handle heavy torque without failing?

The clamps use double solid stainless-steel T-nuts and robust screw threads to distribute load and resist loosening under high torque. Their original T-nut design reduces slippage and provides a more reliable mechanical engagement than single-nut clamps.

• Double solid T-nuts for higher clamping strength
• Wide band that spreads pressure across the hose
• Coarse, durable screw thread for repeatable tightening
• Engineered to resist torque-related deformation

Will these clamps resist corrosion in demanding environments?

Yes — every component is made from 304 stainless steel, chosen for its balance of corrosion resistance and mechanical strength. That makes them suitable for outdoor, marine-adjacent, and engine-bay applications where moisture and road salts are present.

• 304 stainless-steel band, T-nuts, and screws
• Machined finishes to reduce crevice corrosion
• Long-lasting performance in wet or humid conditions
• Low maintenance compared with plated alternatives

Will these clamps damage my hoses or silicone couplers?

They’re designed to be hose-friendly: a smooth inner wall, rounded band edges, and a curved belt edge all reduce cutting and abrasion. The wide band also spreads clamp pressure so delicate silicone or rubber hoses are less likely to be pinched or deformed.

• Rounded edges prevent sharp contact points
• Smooth inner surface minimizes abrasion
• Wide band distributes clamping force evenly
• Suitable for silicone, rubber, oil, water, and gas hoses

What sizes and applications are these clamps best suited for?

Each clamp adjusts to fit hoses and pipes with an outer diameter of about 36–39mm (1.42–1.54"), and the pack contains four clamps for multiple installations. They perform well on exhaust pipes, charge air systems, irrigation lines, and general mechanical or industrial hose fittings.

• Fits 36–39mm (1.42–1.54") outer diameter hoses and pipes
• Commonly used on 1.5-inch OD exhaust and charge-air connections
• Suitable for automotive, industrial, and garden irrigation use
• Pack of 4 for replacement or multi-point installations

Who is this for: CHUN YUNG DA TT Heavy Duty T-Bolt Hose Clamps are aimed at mechanics, DIY vehicle enthusiasts, industrial maintenance teams, and anyone who needs a corrosion-resistant, high-torque clamp that protects hoses. If you work with silicone charge pipes, exhaust joints, or pressurized fluid lines and need a reliable, reusable clamp that won’t cut into the hose, this four-pack delivers robust performance and long service life.
