Proflow's T-bolt hose clamps provide reliable, leak-proof connections for your hose and tube assemblies. These clamps are manufactured from T304 stainless steel with rounded band edges to protect soft hose materials, and yet still provide higher tensile strength, durability, and corrosion resistance than other typical worm gear clamps. Proflow T-bolt hose clamps are ideally suited for medium and heavy-duty applications and include a bolt and locknut.
