    Vacuum Adapters

    Vacuum adapters are portable connectors to connect evacuated tube quickly, using for connecting some vacuum fittings such as KF flanges and fittings, CF flanges and fittings and ISO flanges and fittings, to guarantee vacuum welding and material to reach the standard. Especially material is more strict with connecting to soft state corrugated pipe. If slight difference, maybe it can not reach the ideal vacuum effect after finishing connection when vacuum detection.

    • Tubulated Adapter
    • Pipe Adapter
    • Quick Disconnect Adapter
    • Reducing Adapter

    Features:

    • 1. Standard materials are in 304 and 316L stainless steel.
    • 2. Adapters are supplied with a machining finish. Other finishes are also available.
    • 3. Vacuum Range: ≥10-8Torr
    • 4. Seal Temperature Range:
      • Fluorocarbon FKM (Viton): -5℃~204℃ (23℉~399℉)
      • Silicon: -50℃~180℃(-58℉~356℉)
      • Buna-N (NBR): – 25℃~121℃ (-13℉~250℉)

    Applications:

    • 1. Connection exchange
    • 2. Use Teflon tape for sealing threaded joint.
