Boltza® Ultra 316 Stainless Steel High Torque Hose Clamp – Marine Grade Worm Drive Clip (165-203mm)

• Marine-Grade 316 Stainless Steel: All components (band, housing and screw) are crafted from premium AISI 316 stainless steel. This provides maximum corrosion resistance against saltwater, chemicals, and harsh environments, making it ideal for marine and offshore use.
• High Torque & Clamping Force: Engineered for heavy-duty performance, this clamp achieves very high tightening torque (11.9 Nm recommended) and over twice the band tension of standard hose clips. It maintains a leak-proof seal under intense vibration or pressure, solving stubborn leakage issues where lesser clamps fail.
• Smooth Non-Perforated Band: Designed with a solid band and rolled edges (no perforations) that prevent damage to the hose. The smooth underside and rounded edges protect soft or silicone hoses from cuts and abrasions while tightening, unlike conventional perforated clamps.
• Worm-Drive Mechanism (8mm Hex Screw): Features a robust worm-drive gear and 8 mm A/F slotted hex-head screw for easy tightening with a flat screwdriver or spanner. The heavy-duty housing fully engages the band, allowing precise torque application. Built to SAE J1508 Type HD standards for high-strength hose clamps used in industrial and marine applications.
• Wide Size Range, Sold Individually: Available in sizes from 22–32mm up to 194–232mm diameter. The broad clamping range reduces the need to stock many different sizes. Each clamp is sold as a single unit (one per pack/variant), so you can select exactly the size you need for your project.

Boltza Ultra 316SS High Torque Hose Clamp – a professional heavy-duty hose clip made entirely of marine-grade 316 stainless steel. It’s designed for maximum clamping force and corrosion resistance, perfect for marine, industrial, and high-vibration applications. Premium 316 Stainless Steel: Band, housing and screw are all AISI 316 (W5) stainless steel for superior resistance to rust and corrosion. Ideal for use in saltwater, chemical, and other harsh environments. High Torque Worm-Drive: Rugged worm-drive mechanism and reinforced housing allow safe tightening to high torque levels (up to ~12 Nm). Delivers over 2× the clamping tension of standard hose clamps, comparable to some T-bolt clamps, yet is easier to install. Non-Perforated, Rolled-Edge Band: Smooth band with rolled edges prevents cutting into hoses. No perforations in the band means even pressure distribution and less risk of leaks or hose damage, especially on soft or silicone hoses. Wide Range of Sizes: Available to fit hose diameters from 22 mm up to 232 mm (multiple size options). The wide adjustment range of each clamp means fewer different clamps are needed in your inventory. Choose the exact size for a snug, reliable fit. Professional & Versatile Use: Trusted by marine engineers, mechanics, and technicians for securing fuel lines, exhaust hoses, turbo piping, chemical hoses, and more. Stands up to heavy vibration and temperature extremes without loosening. Each Boltza Ultra hose clamp is sold individually (one per size). This high-torque clamp’s breaking torque is rated around 17 Nm, offering performance on par with much heavier-duty T-bolt clamps. Its lightweight 12 mm band design and hex-head screw make installation and adjustments quick and user-friendly. Upgrade your hose connections with Boltza Ultra clamps for peace of mind in the most demanding conditions.
