WYSIWYKA T-Bolt Hose Clamps 14-Pc Assortment 32–91mm (1"–3") — 304 Stainless, Heavy-Duty Seal

WYSIWYKA's 14-piece T-bolt hose clamp set is a stainless-steel assortment of heavy-duty clamps designed to secure turbo, intercooler, radiator and other large-diameter hoses with a leak-resistant clamp profile.

This kit gathers seven common diameters (two clamps of each size) so you have the right clamp on hand for hose IDs from roughly 32 mm to 91 mm (1"–3"). Each clamp uses a 304 stainless steel band with galvanized hardware, rounded flanged edges, and a T-bolt fastening system engineered for consistent, high-clamp loads where worm-drive clamps may be insufficient. The set is aimed at mechanics, tuners and DIYers who need durable, corrosion-resistant clamps for higher-pressure hoses and demanding environments.

How does the T-bolt design improve sealing versus regular screw clamps?

The T-bolt mechanism delivers a straighter, more uniform clamping force around the hose circumference. That even pressure helps compress the hose and connector evenly, reducing gap points where leaks can start under boost or thermal cycling.

• High clamping force suitable for boost and pressurized hoses
• Wide band reduces localized stress and hose deformation
• Nylon-washered nut helps maintain tension and resists loosening

What sizes are included and what hoses are they best for?

The 14-piece assortment includes two clamps in each of seven size ranges to cover most common plumbing and performance hose IDs. These sizes work well across automotive, marine and irrigation uses where hose inner diameters fall between 32 mm and 91 mm.

• 1" (32–37 mm) and 1.25" (36–44 mm) for small radiator or intake pipes
• 1.5" (44–52 mm) and 1.75" (50–57 mm) for medium intercooler and intake plumbing
• 2" (56–64 mm), 2.5" (70–78 mm), 3" (83–91 mm) for large turbo, coolant and exhaust connections

What materials and finish protect these clamps from corrosion and wear?

WYSIWYKA uses 304 stainless steel bands for long-term rust resistance and durability, plus galvanized nuts and bolts for reliable fastener performance. The bands are polished and have a rounded flanged edge to prevent cutting or chafing of hoses during installation and use.

• 304 stainless steel band resists oxidation in wet and salty conditions
• Galvanized hardware minimizes seizing and makes future removal easier
• Flanged, deburred edges protect hose rubber from abrasion

How do I install and maintain these T-bolt clamps for best results?

Installation is straightforward: slide the clamp over the hose, position it evenly over the fitting shoulder, then torque the nut until the hose is snug without over-compressing. Periodic checks help ensure clamps remain tight after thermal cycles or pressure changes.

• Hand-start the nut then tighten incrementally with a wrench
• Avoid overtightening to prevent hose pinching or distortion
• Inspect for corrosion, loosening, or rubber wear every service interval

Who is this for? WYSIWYKA's 14-piece T-bolt clamp assortment suits automotive enthusiasts, performance tuners, garage technicians, marine owners and homeowners doing robust irrigation or plumbing work. If you install or service turbochargers, intercoolers, radiator plumbing, water pumps or large-diameter hoses and want a corrosion-resistant, high-clamp solution with multiple sizes on hand, this kit simplifies repair and upgrades while reducing the need for last-minute trips to the store.
