Product Details

The Dayco 81181 flexible radiator hose is designed to replace straight or molded radiator hoses when routing allows. This precision-corrugated hose features knitted reinforcement and synthetic EPDM construction combined with an inserted helical steel coil spring, providing superior flexibility and durability for your vehicle's cooling system.

Key Features:

  • 19.875-inch length with 1.5-inch inner diameter on both ends
  • Knitted reinforcement and synthetic EPDM construction meets SAE J20R4, Class D-2 requirements
  • Temperature resistant from -40°F to +257°F (-40°C to +125°C)
  • Corrugated design provides excellent flexibility without flattening or collapse
  • Engineered to resist splitting, ballooning, elongation, ozone, coolants, and environmental elements
  • Includes rubber hose only (no adapters or clamps included)

The corrugated construction delivers exceptional hose flexibility while maintaining shape integrity under pressure. Note: This hose is NOT suitable for fuel or oil transfer—it is specifically engineered for coolant applications in automotive cooling systems.

Great Price Smooth Checkout

I always have a good experience shopping on Autoplicity. Great prices and the parts are always quality and fit.

Quick process and free shipping. I've looked around everywhere for 7063-FSB-AA.

I looked around for few months on where to go to purchase JBA headers for my 01 Tundra. I came across Autoplicity and their prices were untouchable. I even called to speak with a sales representative and he gave me a discount code for my purchase. I would highly recommend doing business and plan on doing more business with them.

Great site. Easy to locate items and they have the best prices! I will be using this site for all my custom parts.

Best price I could find on line, shipped really fast. With how low the price is I was worried but everything came fast and it was the correct parts. This place really keeps the cost of racing down.

I received my ARP head studs as described and on time with zero problems, and cheaper than anywhere else.Will use again!!!

I ordered the part from Autoplicity and it arrived in time and is a great product<br>

Best price I could find anywhere. Almost 10% less than my typical sources and the item shipped in less than 24 hrs.<br>
