Pre-molded hose takes the struggle out of installation

Cooling hose routing can be challenging. Space restrictions and tight bends make using conventional hose impossible without constricting water flow and skinning knuckles. Molded hoses designed for specific applications are the solution. Sierra offers a selection of hoses engineered to match manufacturer specifications and make installation easier. This molded hose is designed for use on circulating pumps on 2.5L and 3.0L engines. Pre-molded bends allow for maximum water flow and end alignment takes the struggle out of connecting to pump and engine ports. To take the frustration out of hose installation, look no further than West Marine and a Sierra molded hose.

Key Features

  • Pre-molded to simplify installation
  • Allows for maximum water flow while making tight bends
  • Connects distribution block and water pump
  • Compatible with MCM 120/2.5L, 140/3.0L & 160/165.
  • Backed by SeaStar Solutions Limited Two-Year Warranty
