Fit (108–116mm) Stainless 304, Flanged Edge","description":"\u003cp\u003e\u003cstrong\u003eWYSIWYKA 4\" T-bolt hose clamps are heavy-duty stainless-steel fasteners made to secure 4\" I.D. hoses with a 5mm wall, fitting hose outer diameters from 108mm to 116mm.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eThese two high-strength clamps combine a 304 stainless-steel band with galvanized hardware and a smooth, flanged edge to prevent hose damage while delivering reliable clamping pressure for turbo charge pipes, intercoolers, radiator hoses and other pressurized or vibration-prone hose connections. They are sold as a 2-pack and are intended for hoses specified by inner diameter; check your hose outer diameter before ordering to ensure the clamp range matches.\u003c\/p\u003e\n\n\u003ch3\u003eHow do these clamps differ from worm-drive or spring clamps?\u003c\/h3\u003e\n\n\u003cp\u003eT-bolt clamps use a single solid band with a bolted crosspiece that provides a more uniform radial squeeze than worm-drive strips or spring clamps. That design reduces localized crushing and offers higher torque capacity, which is important on thick-walled or pressurized hose joins.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eSolid 304 stainless band resists corrosion better than plated steel strips.\u003c\/li\u003e\n  \u003cli\u003eBolted T-bolt allows higher, controlled tightening torque for secure seals.\u003c\/li\u003e\n  \u003cli\u003eFlanged, rounded band edge protects hose material from cuts or abrasion.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill these clamps fit my 4\" intake or turbo hose?\u003c\/h3\u003e\n\n\u003cp\u003eThe clamps are sized for hoses with a nominal 4\" inner diameter and have an adjustable working range of 108–116 mm (4.25\"–4.57\") measured against the hose outer diameter. Because hoses vary in wall thickness, measuring the hose O.D. is essential to confirm compatibility before purchase.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eWorking range: 108–116 mm (4.25\"–4.57\").\u003c\/li\u003e\n  \u003cli\u003eRecommended hose wall thickness: approximately 5 mm for best grip and sealing.\u003c\/li\u003e\n  \u003cli\u003eMeasure your hose outer diameter (O.D.) to match the clamp range accurately.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat materials and construction features improve longevity?\u003c\/h3\u003e\n\n\u003cp\u003eThe band is manufactured from 304 stainless steel for rust resistance, while nuts and bolts are galvanized to stand up to weather and road salts. The band edges are rolled and polished to be smooth and burr-free, reducing chafing and extending hose life at the connection point.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003e304 stainless steel band provides corrosion resistance in automotive and marine environments.\u003c\/li\u003e\n  \u003cli\u003eGalvanized nuts and bolts resist seizing and maintain clamp torque over time.\u003c\/li\u003e\n  \u003cli\u003eFlanged, polished edge prevents cutting into hose material under clamping force.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow should I install and maintain these T-bolt clamps?\u003c\/h3\u003e\n\n\u003cp\u003eInstallation is straightforward: slide the clamp over the hose, position it on the barb or fitting, then tighten the T-bolt evenly while checking alignment. Periodic inspection is recommended—re-torque after initial heat cycles and check for corrosion or slippage in harsh environments.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003ePosition clamp over the coupling or barb before tightening fully.\u003c\/li\u003e\n  \u003cli\u003eTighten gradually and evenly to avoid distorting the hose or fitting.\u003c\/li\u003e\n  \u003cli\u003eInspect after the first few heat cycles and during regular maintenance intervals.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho is this for: These WYSIWYKA T-bolt clamps suit mechanics, tuners and DIYers who need a robust, low-profile clamp for turbo intake systems, intercooler plumbing, radiator hoses, marine and irrigation lines, or any 4\" I.D. hose requiring higher clamping force. If you’re working with thin, oversized, or undersized hoses, measure the outer diameter and consider alternate sizes; otherwise these clamps offer a long-lasting, corrosion-resistant fastening solution ideal for demanding automotive and industrial applications.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Do these clamps fit a 4\" hose?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: They fit hoses with a 4\" nominal I.D. if the hose outer diameter falls between 108–116 mm.
