Features & Benefits
Non-Rotating Needle Tip
Stem rotates but needle tip remains stationary, preventing seat scoring and extending cycle life to 10,000+ samples.
Bubble-Tight Shutoff
Matched-lapped needle tip and integral seat provide zero leakage at full rated pressure differential between sampling cycles.
Purge Connection Option
Integral 1/4" NPT purge port allows nitrogen or process fluid purge to clear sample lines and prevent cross-contamination.
Panel Mountable
Square body and lock nut configuration allow secure mounting in analyser shelters and laboratory panels.
Blow-Out Proof Stem
Anti-blow-out collar and retained stem design prevent stem ejection under high-pressure sampling or line upset conditions.
