• ASIN: B0915B4281

Inlet and Exhaust:

• Inlet: 1/4SAE or 7/16-20UNF
  • Recommended hose: 8 mm ID hose with 1/4 SAE or 7/16-20 UNF fitting for optimal sealing
  • An 8 mm ID hose without fitting can be used, but the seal may not be as tight
  • If the gas reacts with pump oil (e.g., water vapor), use a trap before the inlet.
• Exhaust (filter) port size: 24 mm
  
  • If the gas is harmless to oil but cannot be vented to air, connect an absorber at the exhaust and direct it to a fume hood.  Exhaust port fits 24 mm ID hose
