ECS ECS S54 Exact-fit Water Pipe Connecting Line 013178ecs

ECS S54 Exact-fit Water Pipe Connecting Line

The ECS Exact-fit water line is a perfect upgrade if you're tired of dealing with brittle failure prone parts under your hood. The reinforced fluorosilicone hose has been pre-formed to route the same way your stock line did so you can maintain that clean factory installed appearance. Upgrading the line fitting with a billet aluminum piece eliminates the failure prone plastic fitting giving your cooling system strength.

Included:

Aluminum fitting

  • Material: 6061-T6 Aluminum - MIL-A-8625F Type II Class 2 black anodized for superior corrosion resistance and strength
  • Single-piece design avoiding additional interfaces that may cause leaks
  • Matches OEM style connection to upper coolant hose

Silicone hose

  • Material: Black Reinforced Fluorosilicone Lined Coolant Safe Silicone
  • Pre-formed hose to ensure OEM style routing and appearance
  • Can maintain the use of your stock retaining clips to route the hose in identical locations (due to slight variations in silicone the retainer on the expansion tank may not fit)
  • Pressure tested to ensure 2X operating pressures to ensure reliability
