Gates 24844 Silicone Coolant Hose

This Gates 24844 hose is a straight silicone coolant hose with a 2-3/4 inch inside diameter and a 36 inch length. It is built for engine cooling circuits that require a blue silicone tube and cover rated to SAE 20R1. The hose handles a maximum working pressure of 50 psi at 70 degrees F and a temperature range from -70 to 350 degrees F. It is sold new as bulk hose for custom routing.

Suits cooling system repairs and custom plumbing

Mechanics and builders who need a flexible, high-temperature silicone hose in this exact diameter and length will find it fits the spec. It is not suited for applications that demand a smaller or larger bore, a pre-bent elbow, a different pressure rating, or a hose certified to standards other than SAE 20R1. Buyers requiring oil or fuel compatibility should verify chemical resistance separately.

Verify fitment and regulatory notes

Confirm the 2-3/4 inch inside diameter and 36 inch straight length match your routing before ordering. Ensure the 50 psi working pressure at 70 degrees F and the -70 to 350 degrees F temperature range meet system demands. Note the California Proposition 65 warnings for cancer and reproductive harm associated with this product.

Questions about this item

What clamps do I need for the 2-3/4 in. inside diameter?

Use constant-tension or T-bolt clamps sized for 2-3/4 in. silicone hose; tighten to the clamp maker's torque spec so the 50 psi working pressure at 70 °F is sealed without crushing the tube.

Can I join this hose to my existing rubber radiator hose?

Yes — the straight 36 in. length and SAE 20R1 bore let you cut a section and sleeve it over the rubber end with two clamps; the silicone cover handles the same -70 °F to 350 °F range.

How do I confirm the hose is seated and leak-free after installation?

Pressure-test the cooling system to 50 psi at 70 °F; no coolant weep at the clamps and no hose ballooning means the 24844 is working as intended.
