S.U.R.&.R. Auto SP34 3/4" Heater Hose Spring 3" Steel

The S.U.R.&.R. Auto SP34 is a 3/4-inch steel heater hose spring designed for use with 1/2-inch heater hoses, and is available individually or as a component in S.U.R.&.R.'s HL427 Heater Line Repair Kit. This hose support spring prevents kinking of the hose, fitting around tubing like a sleeve to prevent kinking in tight turns.

Key Features:

• Steel construction for durability
• 3-inch length, 3/4-inch spring size
• Use with 1/2-inch heater hose and requires no specialty tools for installation
• Spring distributes pressure evenly and prevents collapse
• Ideal for tight engine compartments where hoses must bend sharply
• 1-year limited warranty

The spring's purpose is to prevent the hose from bending too sharply, as a sharp bend creates a kink which chokes off coolant flow and can cause dangerous pressure spikes. This simple but effective solution maintains proper coolant circulation and helps prevent overheating issues caused by restricted heater hoses. Perfect for DIY repairs and professional cooling system maintenance.
