WYSIWYKA 4 Pack 1.75" T-Bolt Hose Clamps

WYSIWYKA 1.75" T-bolt hose clamps are heavy-duty stainless-steel clamps designed to securely fasten 1.75" I.D. hoses (50–57mm range) in turbo, intake, radiator and general plumbing applications.

These clamps come as a 4-pack made from 304 stainless steel bands with galvanized nuts and bolts, offering corrosion resistance and long service life. The clamps are intended for hoses with a nominal 1.75" inner diameter and a suggested hose wall thickness near 5mm for best sealing and strength. A rounded flanged edge reduces the risk of cutting into softer hose materials while the polished band minimizes abrasion during installation.

How do I know these clamps will fit my hose?

Measure your hose inside diameter (I.D.) and outer diameter (O.D.) before buying. These clamps are sized for hoses with a nominal 1.75" I.D. and a working tightening range from 1.97" to 2.24" (50–57mm), so check that your hose O.D. falls inside that range when tightened.

• Working range: 50–57mm (1.97"–2.24")
• Recommended hose wall thickness: ~5mm for optimal clamp engagement
• Measure O.D. under normal operating conditions (no extreme compression)
• If hose is very thin or very thick, choose a different clamp or verify fit first

What materials and construction features improve durability?

The band is 304 stainless steel for corrosion resistance and strength, while nuts and bolts are galvanized to resist seizing. The flange is rounded and the band polished to prevent sharp edges from cutting or abrading the hose during tightening and operation.

• 304 stainless steel band — rust and corrosion resistant
• Galvanized fasteners to reduce galling and corrosion
• Rounded flanging to protect hose outer surface
• Polished, burr-free finish for safer installation

Where can I use these T-bolt clamps?

These clamps are built for high-pressure and vibration-prone assemblies like turbo inlet and intercooler piping, but they also work well on radiator hoses, water pump lines, marine hoses and many DIY plumbing or motorbike exhaust connections. They hold up where a standard worm-gear clamp may slip or leak.

• Turbo intake and intercooler piping
• Radiator hoses and water pump connections
• Motorcycle exhaust and general marine hoses
• Irrigation and heavy-duty plumbing applications

How should I install and maintain these clamps for best results?

Tighten evenly and avoid over-torquing which can crush thin hoses. Inspect clamps periodically for corrosion and re-tighten after initial heat cycles. Use a torque wrench or controlled driver when possible to prevent stripped threads or damaged hoses.

• Tighten gradually and evenly until secure; avoid excessive torque
• Check after first heat cycle and re-torque if needed
• Inspect fasteners for corrosion and replace if compromised
• Use recommended clamp size for your hose wall thickness

Who is this for: These WYSIWYKA T-bolt clamps are aimed at mechanics, DIY tuners and professionals who need a reliable, low-slip clamp for turbo systems, intercoolers, radiator lines and other hose assemblies where secure sealing and durability are critical. If you work with 1.75" I.D. hoses and want a corrosion-resistant, heavy-duty fastening solution with rounded flanges to protect hose material, this 4-pack is a practical, value-conscious choice.
