COOLANT HOSE PREMIUM BLUE STRIPE™ 4230SB Premium high-temperature coolant, water and air applications. Suitable for OAT (organic additive technology) engine fluids. Can be used with PowerGrip® Shrink Band Clamps, made from a heat-sensitive thermoplastic with a memory to prevent over- or under-tightening. Also available as customer-made curved hose to SAE 20R4 EC D-1 to fit specific applications and meeting customer specifications. Curved hose recommended for upper, lower, by-pass, heater and other coolant applications. Can be installed without buckling, bending out of shape or straining at the connections. Standards: 4230SB - normal-duty heater hose to SAE 20R3 EC Class D-1 ; 4175SC - heavy-duty radiator hose to SAE 20R1 EC Class D-1, standard wall. Temperature Range: -40°C to +135°C (-40°F to +275°F) and ambient air to +150°C (+302°F) when used in a coolant hose application. Not suitable for conveying fuel or oil. Size: 3/8" to 2.1/4". FEATURES AND BENEFITS Compounded to resist electro-chemical degradation, the leading cause of hose failure. Retains dynamic tension and never needs re-tightening. Eliminates the risk for antifreeze leaks and ground water contamination. Can be installed with an ordinary heat gun. Cover: Wrapped appearance on size 7/8" and as of size 1-1/8".
