AUTO END OF LEG DRAIN 1/2″ Auto End of Leg Drain

Possible Match: Automatic Drip‑Leg (Condensate) Drain

These aren’t medical device drains—rather, they’re self‑draining fittings installed at low points (drip legs) in pneumatic/air‑line systems to automatically expel condensate.

Key Product Example: Shako AD940 Series

• Port Sizes Available: ½”, ¾”, or 1″ (model AD940‑04 is ½”

• Operation: Fully automatic—no manual draining needed. Without system pressure, the drain stays open, letting all condensate out. When pressure is applied and condensate is present, it automatically opens to drain

• Pressure Range: 0.5 to 10 bar (tested up to 12 bar)

• Materials & Build: Body made of aluminum; bowl options include polycarbonate (standard) or optional aluminum; seals are NBR (nitrile rubber)

• Temperature Range: –10 °C to +60 °C

• Design Features: Anti‑vacuum design prevents vacuum formation in the pipeline

• Dimensions (for ½” model): ~69.5 mm wide × 231 mm tall × 77.5 mm deep; weight ~0.5 kg

Another Option: Norgren Drip‑Leg Drain (Part No. AIR000015)

• Fluid Type: Compressed air

• Port Size: ½” PTF (pipe thread female) with an automatic drain connection of 1/8″ NPTF female

• Operation: Automatic. It’s open when unpressurized and closes once bowl pressure reaches ~5 psig (~0.34 bar); reopens automatically to drain when pressure drops below that threshold

• Pressure & Temperature Ratings:

  • Transparent bowl: up to 150 psig (10.3 bar), temperature up to 125 °F (52 °C)

  • Metal bowl: up to 250 psig (17.2 bar), temperature up to 175 °F (79 °C)

• Materials: Zinc body; bowls (transparent or metal) made of polycarbonate or metal; includes sight glass; internal parts include Acetal, Polyester, Stainless Steel, Neoprene, and Nitrile
