Mikalor Supra 68-73mm W4 Heavy Duty Hose Clamp T-Bolt PK43

This listing is for a pack of 43 new Mikalor Supra Heavy Duty T-bolt hose clamps in the 68–73 mm clamping range, grade W4 (all-stainless construction: AISI 304 stainless steel band and housing with a stainless fastening bolt), as stamped on the band visible in the photos. The Mikalor Supra series features a solid cast-housing T-bolt design with a captive nut and double-bolt tensioning mechanism that delivers uniform 360° radial clamping force without band distortion, making it the correct choice for high-pressure hose assemblies, silicone turbo and intercooler couplings, marine exhaust, and heavy-gauge rubber hose in automotive, industrial, and agricultural applications. W4 designation per DIN 3017 / EN ISO 8434 conventions confirms full stainless steel construction throughout — band, housing, bolt, and nut — providing corrosion resistance suitable for salt-water, chemical splash, and high-temperature environments. The 20 mm wide band and wide adjustment range (68–73 mm) accommodate hose ODs in that range with firm, leak-free seating; the double-bolt pattern visible in the photos is the Supra's patented feature (Mikalor, Spain, PAT. marked on the band) providing additional clamping torque distribution.
