Temperature range: -56°C to +180°C
Meets or Exceeds requirements SAEJ20 R4 Class A
US FDA 21/177-2600 compliant
Flame-resistant UL 94-HB compliant
REACH and ROHS compliant
NOT SUITABLE FOR: non-polar liquids such as hydrocarbons, mineral oils, and greases. Strongly attacked by concentrated acids and alkalis, particularly by oxidizing acids such as sulfuric or nitric acid. Also, Silicone Rubber is not suitable coolants containing high-concentration of ethyl-hexanoic acids or coolants with very high pH levels.
OPTIONS:
- SS wire reinforcing ply for heavy “positive” or “negative” pressure
- Anti-abrasion external sleeve: for protection if the hose outer surface is in contact with adjoining parts
