Boltza® Constant Pressure T-Bolt Hose Clamp – SS316 Marine Grade – Extra-Wide 30mm Band with Spring-Loaded Tension, M10 Bolt – (44-47mm)

• Constant Pressure Design with Spring Washers: Automatically maintains tension with 12 Belleville spring washers, compensating for thermal expansion, vibration, or pressure changes. Zero re-tightening required.
• 30mm Extra-Wide Band for Even Sealing: The heavy-gauge stainless steel band distributes clamping force evenly across thick-walled or silicone hoses, preventing hose deformation and ensuring a reliable seal.
• High Torque M10 T-Bolt with Anti-Extrusion Bridge: Fitted with a reinforced bridge and an M10 bolt, allowing secure high-torque fastening without risk of hose pinch-through or pressure escape.
• 316 Stainless Steel Construction – Full Corrosion Protection: Engineered for extreme durability in marine, chemical, or high-temperature environments. All components including bolt, band, and springs are made of marine-grade SS316.
• Industrial-Grade Hose Clamp – Four Size Ranges Available: Choose from 44–47mm, 48–51mm, 64–67mm or 68–73mm. Perfect for turbo piping, marine coolant lines, hydraulic systems, and heavy-duty machinery.

Boltza Industrial Strength. Reliable Seal. Built to Last. The Constant Pressure T-Bolt Clamp is a professional-grade solution for securing hoses in high-performance and high-pressure environments. Designed for reliability, it uses a stack of 12 Belleville spring washers that apply constant clamping force – adapting to hose expansion or contraction automatically. Engineered for Demanding Applications: Each clamp features a 30mm wide band for maximum surface contact, a heavy-duty M10 bolt for high-torque installation, and a fully integrated anti-extrusion bridge to prevent hose bulging or shearing. 100% SS316 Marine Grade Stainless Steel: Designed for longevity and performance, even in corrosive environments like marine engine bays or chemical plants. No mixed metals – all parts are marine-grade. High Performance – No Maintenance: These clamps hold firm under constant vibration, boost pressure, and thermal cycling. Commonly used in turbocharger piping, marine cooling systems, hydraulic lines, or agricultural machinery. Once fitted, they maintain sealing pressure with zero manual intervention. Available Sizes: 44–47mm 48–51mm 64–67mm 68–73mm Choose the correct range based on your hose’s outer diameter. Each clamp offers slight adjustability within its range.
