Boltza® Ultra 316SS High-Torque Worm-Drive Hose Clamp (Marine Grade, Various Sizes)

Fully 316 Stainless (W5):  Manufactured entirely from marine-grade AISI 316 stainless steel (band, screw, and housing) for ultimate corrosion resistance. Suitable for use in saltwater, chemical, and outdoor environments without rusting. Extreme Clamping Power: High-torque worm-drive mechanism generates twice the tightening force of standard clamps. Securely seals against stubborn leaks and withstands heavy vibration where ordinary hose clips would loosen. Smooth Rolled-Edge Band: The non-perforated band with rolled edges protects hoses from being cut or damaged. Ensures an even, leak-free seal on all hose types (ideal for reinforced or silicone hoses) while preventing hose bulge through band slots.Professional Grade Design: Features a reinforced 8mm hex-head screw and one-piece housing for reliable high-torque tightening. Conforms to SAE J1508 HD clamp standards for heavy-duty performance. Lighter and easier to install than bulky T-bolt clamps, yet it offers comparable strength. Multiple Sizes (22–232mm): Wide range of sizes available, from 22–32mm small hoses up to 194–232mm large pipes. This broad clamping range reduces inventory needs. Each clamp is sold singly, so you can purchase just the sizes required for your project.

Boltza® Constant Pressure T-Bolt Hose Clamp – 68–73mm (316 Stainless Steel)

Self-adjusting clamp maintains sealing pressure under boost, vibration, or heat cycles. 30mm stainless band distributes clamping force evenly for large-diameter hoses. M10 T-bolt and anti-extrusion liner prevent leaks and hose damage. Constructed from full SS316 stainless for long-term durability and corrosion resistance. Ideal for 68–73mm OD hoses – suitable for marine exhausts, turbo piping, or agricultural machinery.

Boltza® Constant Pressure T-Bolt Hose Clamp – 64–67mm (316 Stainless Steel)

Spring-loaded clamp with 12 Belleville washers maintains constant sealing pressure. Extra-wide 30mm band and M10 bolt offer superior strength and pressure distribution. Integrated bridge protects hose under clamp from distortion or extrusion. Marine-grade 316 stainless steel body resists corrosion and high heat. Suitable for 64–67mm OD hoses – perfect for coolant, turbo, or industrial pipe connections.

Boltza® Constant Pressure T-Bolt Hose Clamp – 48–51mm (316 Stainless Steel)

Automatically self-adjusts tension using a 12-spring washer stack for constant pressure. Extra-wide 30mm stainless band ensures reliable sealing on heavy-duty hoses. M10 bolt and integrated anti-extrusion bridge prevent hose bulging or deformation. Built from corrosion-proof 316 stainless steel for use in marine, automotive or industrial settings. Fits hoses with 48–51mm OD – ideal for high-pressure systems and boost pipe installations.

Boltza® Constant Pressure T-Bolt Hose Clamp – 44–47mm (316 Stainless Steel)

Constant pressure system with 12 Belleville spring washers adapts to vibration and heat changes. Heavy-duty 30mm wide band provides even pressure and protects reinforced or silicone hoses. M10 T-bolt design allows high-torque installation with anti-extrusion bridge for hose security. Full 316 stainless steel construction resists rust in marine, chemical, or outdoor environments. Designed for hoses with 44–47mm OD – ideal for turbocharger, coolant, or fluid transfer systems.
