#12 Pro-Lite Inner Spring 4ft

The #12 Pro-Lite Inner Spring 4ft is a precision-engineered hose support component designed for high-performance fluid systems requiring reliable hose management and vibration isolation. Built by EARLS, a recognized leader in performance plumbing solutions, this inner spring support is engineered for racing applications, fuel systems, and hydraulic lines where hose integrity and system longevity are non-negotiable. The 4-foot length provides extended coverage for complex routing in engine bays and custom installations, making it ideal for builders and technicians who demand professional-grade hardware.

This inner spring support is rated for 12 AN (7/8-inch nominal) hose and features the Pro-Lite 350 construction, engineered to minimize weight while maintaining structural rigidity under thermal cycling and vibration stress. The inner spring design prevents hose collapse under vacuum conditions and reduces stress concentration at connection points, critical in fuel delivery and coolant systems operating under boost or high flow rates. The Pro-Lite specification indicates a lightweight composite or specialized spring steel construction optimized for motorsports applications where unsprung weight matters and thermal stability is essential.

Professional fabricators, race teams, and restoration specialists benefit most from this component when constructing custom fuel systems, turbo coolant lines, or hydraulic brake circuits where OEM support infrastructure is absent or inadequate. The 4-foot continuous length suits engine compartment layouts ranging from tight domestic V8 builds to European inline configurations, eliminating the need for multiple shorter sections. Installation is straightforward—the spring simply wraps around the AN hose at intervals, securing with hose clamps or adhesive-backed fasteners, providing immediate protection against chafing, vibration fatigue, and premature hose failure.
