WYSIWYKA T-Bolt Hose Clamp Kit — 14-Piece 304 Stainless Steel, 32–91mm Heavy-Duty Clamps for Turbo & Radiator

WYSIWYKA 14-piece T-bolt clamp kit is a stainless-steel assortment designed to give leak-resistant, heavy-duty clamping for 1"–3" (32–91mm) hose applications.

This kit groups seven common T-bolt clamp sizes (two of each) into a single set so you have the correct clamp for turbo intake, intercooler plumbing, radiator hoses and other high-pressure or vibrating hose connections. Each clamp is built from 304 stainless-steel bands with galvanized fasteners, a rolled flanged edge, and a nylon-washered nut to reduce slippage and protect hose material. The set is aimed at home mechanics, performance shops and DIYers who want a durable, corrosion-resistant alternative to worm-drive clamps.

Which hose sizes and working ranges are included in the set?

The assortment covers seven sizes and two clamps per size for quick replacement or multi-point connections. Sizes are selected to match commonly used hose inner diameters from 32mm up to 91mm.

• 1" (32–37 mm)
• 1.25" (36–44 mm)
• 1.5" (44–52 mm)
• 1.75" (50–57 mm)
• 2" (56–64 mm)
• 2.5" (70–78 mm)
• 3" (83–91 mm)

How durable and corrosion-resistant are these clamps?

Materials and construction focus on longevity for automotive and marine environments. The band uses 304 stainless steel for corrosion resistance while the nuts and bolts are galvanized to withstand moisture and road salts.

• 304 stainless-steel band resists rust and offers tensile strength
• Galvanized fasteners add extra protection against corrosion
• Polished, burr-free surface minimizes abrasion to hoses

How does the flanged T-bolt design protect hoses and prevent leaks?

The rolled flanging on the band edge removes sharp edges that can cut hose material under pressure. The T-bolt configuration distributes clamping force evenly and the nylon-washered nut helps hold torque for a more secure seal than standard screw clamps.

• Rounded flange guards against hose cuts and premature wear
• Even radial compression reduces localized pressure points
• Nylon washer on the nut resists loosening from vibration

Where are these T-bolt clamps typically used?

This kit is suitable for any application where a strong, vibration-resistant connection matters. Typical uses include turbo plumbing, intercooler hoses, radiator and coolant lines, marine and irrigation connections, or performance exhaust and intake systems.

• Turbo and intercooler piping where boost pressures require secure seals
• Radiator and coolant hoses exposed to temperature cycles
• Water pumps, marine hoses, and motorcycle applications

Who is this for: DIY mechanics, performance tuners, small repair shops and hobbyists who need a ready assortment of heavy-duty clamps for automotive, marine or industrial hoses will appreciate this WYSIWYKA kit. It’s particularly useful when replacing multiple worn clamps, upgrading to a more robust clamping method for boost or coolant systems, or when you want corrosion-resistant hardware on projects exposed to moisture, salt or vibration.
