High-Temperature Coolant Hose Elbows

Temperature Range: -65° to 350° F
Material: Silicone Rubber
Color: Blue
For Clamp Type: Worm Drive

Move coolant around tight turns in crowded spaces. Also known as radiator hose, these elbows are actually short lengths of hose that have been formed into an elbow. Made of silicone, they withstand high heat and are tough enough to stand up to wear and tear. They meet SAE J20R1 Class A, which is a performance and durability standard for hose in engine cooling systems.

Extreme-Temperature Coolant Hose

Temperature Range: -65° to 500° F
Material: Silicone Rubber
Color: Red
For Clamp Type: Worm Drive

Reinforced by aramid fabric, this silicone rubber hose handles higher temperatures than any other coolant hose we offer. It’s designed to handle the heat of a turbocharged engine. The reinforcement also makes it last longer than standard silicone rubber coolant hose when exposed to extreme vibration.

High-Temperature and High-Purity Soft Rubber Tubing

Semi-Clear Tubing

Semi-Clear Tubing with Braid

Not only is this tubing cured with platinum for high purity, it can handle higher temperatures than any of our other high-purity soft tubing. It is free of plasticizers like DEHP and will not impart tastes or odors to the fluid running through it. Tubing is not for use in medical applications. It is semi-clear, so you get a limited view inside the line. Tubing is flexible and bends easily around objects.

Tubing with a polyester braid reinforcement has extra strength to withstand higher pressures than nonreinforced tubing.

Tubing with a pump tube number is designed for use with metering (peristaltic) pumps; it can handle repeated bending and flexing.
