4 Ply Silicone Sleeve 4. 5in I.D. x 12in long

The 4 Ply Silicone Sleeve 4.5in I.D. x 12in long is a high-temperature hose protection and routing component designed for custom automotive cooling systems, intercooler piping, and performance intake applications. Built by Vibrant Performance, this silicone sleeve is ideal for professionals and enthusiasts who demand reliability in extreme-heat environments.

Constructed with four-ply reinforced silicone, the sleeve delivers exceptional durability and flexibility, outperforming single-wall rubber or plastic alternatives. It maintains structural integrity and protective function through years of demanding service, with thermal stability exceeding 300°F. The multi-ply design distributes stress evenly and resists abrasion from engine bay vibration and contact with sharp edges or fasteners.

This sleeve is perfect for technicians, fabricators, and serious performance builders looking to enhance their cooling systems. The 4.5-inch inner diameter accommodates standard large-diameter hose assemblies common in performance cooling and intake systems, while the 12-inch length provides ample coverage for critical transition points and vulnerable hose sections.
