PEROMI T-Bolt Hose Clamps 10-Pack for 2" ID (58–65mm) — Heavy-Duty Stainless Steel, Rounded Flange

PEROMI's 10-pack T-bolt hose clamps secure 2" ID (58–65mm OD) silicone and rubber hoses with heavy-duty stainless steel construction and protective rounded flanges to prevent cuts and leaks.

If you work on turbos, intercoolers, radiators, marine systems, or industrial lines, you need clamps that fit accurately and hold under pressure. These clamps are sized for hoses with a 2-inch inner diameter (measuring 58–65mm outside diameter) and come as a set of ten, so you can outfit multiple connections at once. Built from solid stainless steel with zinc-coated nuts and color-plated springs, they balance strength, corrosion resistance, and ease of installation.

How do these clamps protect silicone and rubber hoses during installation?

PEROMI T-bolt clamps use a rounded arc flanging design along the band edge that minimizes sharp contact points. That rounded profile reduces the risk of slicing or nicking hose material when you tighten the clamp, preserving the hose integrity and preventing premature failures.

• Rounded flanged band prevents cutting into hose walls
• Smooth, burr-free surface finish for gentle contact
• Tight, even compression from the T-bolt mechanism for a secure seal

Will these clamps resist rust and hold up in harsh environments?

Yes. The main body is stainless steel while fasteners are zinc-coated and the springs are color-plated zinc, giving multiple layers of corrosion defense. That combination helps the clamps tolerate engine bays, marine spray, and outdoor exposure better than plain-steel fittings.

• Stainless-steel band resists oxidation and staining
• Zinc-coated nuts and plated springs reduce corrosion on moving parts
• Durable finish maintains clamping strength over time

What hose sizes and applications are these clamps suitable for?

These clamps are specified for hoses with a 2-inch internal diameter and an outer diameter between 58 and 65mm; always measure your hose OD before installing. They’re versatile for turbo intake connections, intercooler pipes, radiator and coolant hoses, exhaust-to-flex couplings, marine lines, irrigation systems, and many industrial hoses.

• Fits 2" ID hoses with 58–65mm OD
• Works on silicone, rubber, and reinforced hoses
• Common uses: turbo/intake, intercooler, radiator, marine and industrial lines

How do you install and tighten a PEROMI T-bolt clamp safely?

Installation is straightforward: slip the clamp over the hose, position it over the barb or fitting, and tighten the T-bolt nut evenly until snug. Use a torque-limited driver if available; stop when the clamp compresses the hose for a leak-free seal but before over-stressing the material.

• Slide over hose, center on fitting, and hand-start the nut
• Tighten evenly with a suitable wrench or socket to avoid distortion
• Use torque guidelines for silicone or thin-walled hoses to prevent over-compression

Who is this for? Mechanics, performance tuners, marine technicians, fleet maintenance crews, and DIYers who install or service turbo, cooling, and fluid transfer systems will appreciate a dependable clamp that fits 2" hoses and reduces hose damage. If you need a bulk set to keep a workshop stocked or to upgrade multiple connections for improved reliability, the PEROMI 10-pack provides consistent sizing, durable materials, and a protective band design to minimize hose wear. For any sizing or installation questions, PEROMI offers customer support to help ensure the right fit and function for your application.
