What type of hose is recommended to pump or transfer EnSolv?
The number one choice is Teflon hose, followed by Viton. HDPE hoses are adequate for short term exposures, but if the hose will be holding EnSolv for extended periods of time it will become brittle eventually and possibly crack. Natural rubber is absolutely incompatible. Most plastic hoses are okay for short term transfer, but for immersion or continuous transfer your best bet is Teflon or Viton.
