QWORK 3" T-Bolt Hose Clamp for 3" ID (83–91mm) — 10-Pack, 304 Stainless Steel Heavy-Duty

QWORK 3" T-bolt hose clamp is a heavy-duty 304 stainless-steel clamp sold in a 10-pack, sized to securely seal 3" (83–91mm) inner-diameter hoses for intake, intercooler, radiator, and custom piping applications.

This kit brings commercial-grade clamping performance to workshop and DIY projects. Each clamp uses a strong T-bolt fastening mechanism and a rounded-edge band to deliver uniform compression without cutting or deforming flexible hose materials. The corrosion-resistant 304 stainless construction resists rust and keeps clamps serviceable in demanding engine-bay and outdoor environments.

How does this T-bolt clamp differ from a standard worm-drive clamp?

The T-bolt design offers a stiffer, more even clamping force than typical worm-drive clamps, making it better suited for high-pressure or high-vibration hose connections. The wider band distributes pressure across the hose wall, lowering the risk of leaks or hose deterioration over time.

• Robust stainless-steel T-bolt fastener for higher torque capacity.
• Wider, rounded-edge band reduces localized cutting and abrasion.
• Uniform compression over the hose circumference to maintain a consistent seal.

Will these clamps fit my 3" intake or intercooler hose?

Yes — each clamp is sized to fit hoses with an inner diameter between 83mm and 91mm (about 3.27"–3.58"), covering typical 3" hose variations used on many intake, intercooler, and turbo plumbing setups. Measure the hose outside diameter if it is thick-walled to confirm compatibility.

• Working range: 83mm–91mm (3.27"–3.58").
• Intended for nominal 3" ID hoses; thicker liners may require checking outside diameter.
• Sold as a 10-pack for multi-clamp assemblies or spares.

What are the material and durability benefits of the QWORK clamp?

Manufactured from 304 stainless steel, the clamps resist rust and corrosion commonly found in engine bays and outdoor installations, extending service life. The smooth, rolled band edges protect softer silicone and rubber hoses from cuts while maintaining consistent clamp pressure during thermal cycles.

• 304 stainless resists oxidation and corrosion for longer field life.
• Rounded band edges protect hose integrity and prevent slippage.
• High-strength bolt and nut assembly tolerates repeated tightening cycles.

How should I install and torque these T-bolt clamps for best results?

Position the clamp so the band contacts the hose over the coupling or barb, then tighten the T-bolt gradually until the hose is snug and leak-free. Avoid over-torquing; aim for even, firm compression and re-check after a short run-in period when used on engine or pressurized systems.

• Seat clamp over the hose barb or coupling with band centered on the seal area.
• Tighten evenly using a socket or wrench; avoid sudden high torque steps.
• Re-inspect and re-torque after initial operation or heat cycles.

Who is this for: The QWORK 3" T-bolt clamp 10-pack is aimed at mechanics, performance tuners, and hobbyists who install or service turbo, intake, intercooler, and radiator plumbing. It’s also suitable for marine, industrial, and agricultural applications where a corrosion-resistant, high-strength clamp is required. Choose this pack if you need reliable, bulk-supplied clamps that protect soft hoses while delivering even sealing pressure across your critical hose connections.
