2 1/2" High Temperature Heater HoseThis heater hose is a very lightweight yet durable thermoplastic rubber that is reinforced with an external polypropylene helix and is rated for up to 225 degree operating temperature. Lightweight and pliable hose can form to fit various applications. Flexible, compressible, and crush resistant, this material also meets FMVSS 302 flame standards. For Ducted Heaters, we recommend 4'- 6' of hose or less per duct. Adding more than 6' of hose per duct will result in less air flow to the vent due to resistance. |
