High-Temperature Silicone Hose
Specialty high-temperature silicone hose rated for 250°C continuous operation. VMQ + specialty fillers. Automotive, industrial, and energy applications. Custom sizes.
REACH RoHS
Product Overview
Standard platinum-cured silicone tubing is rated for continuous operation up to 220°C. For applications requiring sustained temperatures above this limit, Rekky Technology offers High-Temperature Silicone Hose formulated with specialty VMQ compounds and heat-stabilizing fillers that extend the continuous operating temperature to 250°C and allow short-term spikes up to 300°C.
This specialty hose is engineered for automotive turbocharger systems, industrial oven exhaust, steam sterilization equipment, and emerging hydrogen energy applications where elevated temperatures are the norm rather than the exception. The compound uses phenyl-modified silicone (PMQ) and iron oxide red fillers to improve thermal stability and oxidation resistance at extreme temperatures.
Despite the high-temperature formulation, the hose maintains good flexibility at low temperatures (down to -40°C) and can be reinforced with glass fiber braid or stainless steel wire for pressure and vacuum applications. Custom colors including the distinctive iron-oxide red are available for high-temperature identification.
